vertical vent system does not satisfy the criteria for

Category I venting, it must be vented as a Category III

system.

All Brute Deluxe vent systems which discharge

horizontally (without the use of a power venter) are

considered Category III vent systems.

2.1.2 Intake Combustion Air

The combustion air can be taken through the

wall, or through the roof. When taken from the wall,

it must be taken from out-of-doors by means of the

Bradford White horizontal wall terminal (see Table 1).

When taken from the roof, a ﬁeld-supplied rain cap or

an elbow arrangement must be used to prevent entry of

rain water (see Figure 2).

2.2.2 Category I Vent

When vented as a Category I appliance, the

vent system must conform to the National Fuel Gas

Code (ANSI Z223.1-Latest Edition) in the U.S., or in

Canada, to the Natural Gas and Propane Installation

Code (CSA B149.1 latest edition). The vent system

must be sized and installed for a Category I Fan-

Assisted Appliance.

If chimney height is greater than 25 feet, or

if multiple units are vented into the same vertical

vent, a barometric damper must be installed on each

appliance, such that the ﬂue draft does not exceed

(negative) 0.1 in. w.c.

Use single-wall galvanized pipe, per Table

4, for the combustion air intake (see Table 1 for

appropriate size). Route the intake to the heater as

directly as possible. Seal all joints with tape. Provide

adequate hangers. The unit must not support the

weight of the combustion air intake pipe. Maximum

linear pipe length allowed is 50 feet (15.2m). Three

elbows have been calculated into the 50-foot (15.2m)

linear run. Subtract 10 allowable linear feet (3.0m) for

every additional elbow used (see Table 1). When fewer

than 3 elbows are used, the maximum linear pipe

length allowed is still 50 feet (15.2m).

If using a power venter for any type of Category

I venting, the draft should be set between (negative)

0.01 and 0.05 in. w.c.

2.2.3 Common Venting Systems

Joint Sealing Permanent duct tape or aluminum tape

Brute Deluxe units are Category I fan-assisted

when vented vertically and adhering to all applicable

codes. Brute Deluxe units are not allowed to be

vented into a common horizontal vent system, unless

a properly sized vent fan is used, and the common

vent system is properly designed by the vent fan

manufacturer or a qualiﬁed engineer. When common

venting Brute Deluxe fan-assisted unit with other

appliances through one shared vertical duct called a

“common vent”, special care must be taken by the

installer to ensure safe operation. In the event that

the common vent is blocked, it is possible, especially

for fan-assisted devices, to vent backwards through

non-operating appliances sharing the vent, allowing

combustion products to inﬁltrate occupied spaces.

If the appliances are allowed to operate in this

condition, serious injury or death may occur.

Table 4. Required Combustion Air Piping Material.

The connection for the intake air pipe is on the

ﬁlter box. The Brute Deluxe appliances may have

venting and combustion air ducting attached to the top

or the back. They are shipped with the connections

at the top. For attaching either or both pipes to the

back, the mounting ﬂanges are reversible by removing

the mounting screws and orienting the ﬂanges in the

desired position. Replace the screws after positioning

ﬂanges. Run a bead of silicone around the collar and

slide the pipe over the collar. Secure with sheet metal

screws.

In addition to air needed for combustion, air

shall also be supplied for ventilation, including all air

required for comfort and proper working conditions

for personnel. The Brute Deluxe loses less than 1

percent of its input rating to the room, but other heat

sources may be present.

WARNING

Operation of appliances with a blocked common

vent may lead to serious injury or death. Safety

devices must be implemented to prevent blocked

common vent operation. If safe operation of all

appliances connected to a common vent cannot

be assured, including prevention of spillage of flue

gasses into living spaces, common venting should

not be applied, and appliances should each be

vented separately.

2.2 Venting

2.2.1 Vent Categories

Depending upon desired Brute Deluxe venting,

it may be considered a Category I or a Category III

appliance. In general, a vertical vent system will be

a Category I system. However, in rare instances, a

Brute Deluxe’s vertical vent system may be considered

Category III. In the U.S., the National Fuel Gas Code

(ANSI Z223.1), or in Canada the Natural Gas and

Propane Installation Code (CSA B149.1), deﬁnes a

Category I vent system, and includes rules and tables

to size these vent systems. If the Brute Deluxe’s

as required in the venting system manufacturer’s

installation instructions. Horizontal portions of the

venting system must be supported to prevent sagging

and may not have any low sections that could trap

condensate.

The unit must not support the weight of the vent

pipe. Horizontal runs must slope downwards not less

than ¼ inch per foot (2 cm/m) from the unit to the vent

terminal.

L’appareil ne doit pas supporter le poids de la

gaine d’évent. Les parties horizontales doivent être

installées avec une pente de 2 cm/m (1/4 inch par pied)

descendant de l’appareil vers la sortie de l’évent.

Reference Table 1 for the size of the Category

III vent system. Up to three elbows can be used with

50 linear feet (15.2m) of pipe. Subtract 10 allowable

linear feet (3.0m) for every additional elbow used.

AVERTISSEMENT

Le fonctionnement d’appareils connectés à un

évent commun bouché peut provoquer de sérieuses

blessures corporelles ou la mort. Des dispositifs de

sécurité doivent être mis en place pour empêcher

que les appareils soient utilisés avec un évent

commun bouché. Si un fonctionnement sécuritaire

de tous les appareils reliés à un évent commun et si

la prévention des dégagements accidentels de gaz

de combustion dans des zones habitées ne peuvent

pas être assurés, un évent commun ne doit pas

être mis en place et les appareils doivent être munis

d’évents individuels séparés.

It is for this reason that, in addition to

following proper vent sizing, construction and safety

requirements from the National Fuel Gas Code,

ANSI Z223.1 or in Canada, from the Natural Gas

and Propane Installation Code (CSA B149.1) as

well as all applicable local codes, it is required that

installers provide some means to prevent operation

with a blocked common vent. It is suggested that a

blocked vent safety system be employed such that if

the switch from one appliance trips due to excessive

stack spill or back pressure indicating a blocked vent

condition, that all appliances attached to the vent be

locked out and prevented from operating. Note that

the Brute Deluxe is equipped with a blocked vent

safety (pressure) switch, as shipped. However, this

safety switch has only been designed and tested to

be effective in installations where the Brute Deluxe

is vented separately and NOT common vented with

other appliances. As an additional precaution, it is

recommended that a Carbon Monoxide (CO) alarm be

installed in all enclosed spaces containing combustion

appliances. If assistance is required in determining

how a blocked vent safety system should be connected

to a Bradford White product, please call Applications

Engineering at the Rochester phone number on the

back cover of this manual.

2.3 Locating Vent & Combustion Air

Terminals

2.3.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent

terminal must be used, and is listed in the installation

and operation manual. The terminal provides a means

of installing the vent piping through the building wall,

and must be located in accordance with ANSI Z223.1/

NFPA 54 and applicable local codes. In Canada, the

installation must be in accordance with CSA B149.1

and local applicable codes. Consider the following

when installing the terminal:

1. Figure 3 shows the requirements for mechanical

vent terminal clearances for the U.S. and Canada.

2. Locate the vent terminal so that vent gases cannot

be drawn into air conditioning system inlets.

3. Locate the vent terminal so that vent gases cannot

enter the building through doors, windows,

gravity inlets or other openings. Whenever

possible, locations under windows or near doors

should be avoided.

4. Locate the vent terminal so that it cannot be

blocked by snow. The installer may determine

that a vent terminal must be higher than the

minimum shown in codes, depending upon local

conditions.

5. Locate the terminal so the vent exhaust does

not settle on building surfaces or other nearby

objects. Vent products may damage such surfaces

or objects.

Refer to the installation and operating

instructions on all appliances to be common vented

for instructions, warnings, restrictions and safety

requirements. If safe operation of all appliances

connected to a common vent cannot be assured,

including prevention of spillage of ﬂue gases into

living spaces, common venting should not be applied,

and appliances should each be vented separately.

2.2.4 Category III Vent

is likely to be too large for proper venting of the

appliances remaining connected to it.

At the time of removal of an existing boiler, the

following steps shall be followed with each appliance

remaining connected to the common venting system

placed in operation, while the other appliances

remaining connected to the common venting system

are not in operation.

(e) A copy of all installation instructions for all

Product Approved side wall horizontally

vented gas fueled equipment, all venting

instructions, all parts lists for venting

instructions, and/or all venting design

instructions shall remain with the appliance

or equipment at the completion of the

unit takes its combustion air through a duct from a

side wall. Consider the following when installing the

terminal:

1. Do not locate the air inlet terminal near a source

of corrosive chemical fumes (e.g., cleaning ﬂuid,

chlorinated compounds, etc.)

2. Locate the terminal so that it will not be subject

to damage by accident or vandalism.

3. Locate the combustion air terminal so that it

cannot be blocked by snow. The National Fuel

Gas Code requires that it be at least 12 inches (30

cm) above grade, but the installer may determine

it should be higher, depending upon local

conditions.

4. If the Brute Deluxe is side-wall vented to the

same wall, locate the vent terminal at least 3

feet (0.9m) horizontally from the combustion air

terminal, and locate the vent terminal at least 1

foot (0.3m) above the combustion air terminal

(see Figure 3).

The Brute Deluxe’s gas train allows the user to

pipe the gas from either the right side or the left side

of the unit. As shipped, the right side of the gas train is

capped off, and there is a manual valve on the left side.

If desired, the manual valve on the left side of the gas

train may be moved to the right side, and the cap on

the right side may be moved to the left.

10. The appliance and its gas connection must be

leak tested before placing it in operation.

11. Purge all air from gas lines.

WARNING

Do not use open flame to check for leaks. An open

flame could lead to explosion, which could result in

property damage, serious injury or death.

Review the following instructions before

proceeding with the installation.

1. Verify that the appliance is ﬁtted for the proper

type of gas by checking the rating plate. Brute

Deluxe appliances are equipped to operate at

elevations up to 10,000 feet (3050m). Brute

Deluxe appliances may be adjusted to operate

properly at altitudes above 2500 feet (see Section

6.5.2) and the input will be reduced if the heating

value of the gas supply is below sea level values.

2. The maximum inlet gas pressure must not

exceed 13" w.c. (3.2kPa). The minimum inlet gas

pressure is 5 in. w.c. (1.2 kPa).

4A.3 Water Flow Requirements — Boiler

A hydronic heating (closed loop) application

recirculates the same ﬂuid in the piping system. As a

result, no new minerals or oxygen are introduced into

the system. To ensure a proper operating temperature

leading to long boiler life, a ﬂow rate has been

established based on the ﬂuid temperature rise for this

speciﬁc size boiler.

Pump-mounted boilers can be ordered for use in

primary secondary piping systems. The pumps used

are sized for the head loss through the heater, plus 30

feet (9.1 m) of full-sized piping (same size as boiler

outlet) and a normal number of ﬁttings.

Table 8 speciﬁes water ﬂow rates for boilers,

which will enable the user to size a pump. The head

loss shown is for the heater only, and the user will

need to add the head loss of the system piping to

properly size the pump.

The minimum inlet water temperature for the

Brute Deluxe is 120°F (49°C) to avoid condensing on

the copper coils.

SECTION 4A.

Water Connections —

Brute Deluxe Boiler

4A.1 Heating System Piping:

Hot Supply Connections — Boiler

NOTE: This appliance must be installed in a closed

pressure system with a minimum of 12 psig (82.7

kPa) static pressure at the boiler.

Hot water piping should be supported by suitable

hangers or ﬂoor stands. Do not support piping with

this appliance. Due to expansion and contraction of

copper pipe, consideration should be given to the type

of hangers used. Rigid hangers may transmit noise

through the system resulting from the piping sliding in

the hangers. It is recommended that padding be used

when rigid hangers are installed. Maintain 1" clearance

to combustibles for hot water pipes.

Pipe the discharge of the relief valve (full size)

to a drain or in a manner to prevent injury in the event

of pressure relief. Install an air purger, an air vent,

a diaphragm-type expansion tank, and a hydronic

ﬂow check in the system supply loop. Minimum ﬁll

pressure must be 12 psig (82.7 kPa). Install shutoff

valves where required by code.

4A.4 Freeze Protection — Boiler

Boiler installations are not recommended in

areas where the danger of freezing exists unless proper

precautions are made for freeze protection. A non

toxic, heating system, anti-freeze may be added to

the hydronic system provided that the concentration

does not exceed 50% and the anti freeze contains an

anti foamant. When a 50/50 mixture is used, increase

the water ﬂow requirements by 15%, and increase the

head loss requirements by 20%.

Suggested piping diagrams are shown in Figures

4, 5, 6, 7 and 8. These diagrams are meant only as a

guide. Components required by local codes must be

properly installed.

4A.2 Cold Water Make-Up — Boiler

1. Connect the cold water supply to the inlet

connection of an automatic ﬁll valve.

Power outage, interruption of gas supply, failure

of system components, activation of safety devices,

etc., may prevent a boiler from ﬁring. Any time a

boiler is subjected to freezing conditions, and the

boiler is not able to ﬁre, and/or the water is not able

to circulate, there is a risk of freezing in the boiler

or in the pipes in the system. When water freezes,

it expands. This can result in bursting of pipes in the

system, or damage to the boiler, which could result in

leaking or ﬂooding conditions.

IMPORTANT NOTES: Different glycol products

may provide varying degrees of protection. Glycol

products must be maintained properly in a heating

system, or they may become ineffective. Consult

the glycol specifications, or the glycol manufacturer,

for information about specific products,

2. Install a suitable back ﬂow preventer between the

automatic ﬁll valve and the cold water supply.

3. Install shut off valves where required.

NOTE: The boiler, when used in connection with a

refrigeration system, must be installed so the chilled

medium is piped in parallel with the boiler with

appropriate valves to prevent the chilled medium

from entering the boiler.

The boiler piping system of a hot water heating

boiler connected to heating coils located in air

handling appliances where they may be exposed to

refrigerated air circulation must be equipped with ﬂow

control valves or other automatic means to prevent

gravity circulation of the boiler water during the

cooling cycle.

A boiler installed above radiation level, or as

required by the authority having jurisdiction, must be

provided with a low water cutoff device either as a part

of the boiler or at the time of boiler installation.

maintenance of solutions, and set up according to

your particular conditions. Never use ethylene glycol

SECTION 4B.

Water Connections —

Brute Deluxe Water Heater

If the Brute Deluxe water heater is installed in

a closed water supply system, such as one having a

backﬂow preventer in the cold water supply line, the

relief valve may discharge periodically, due to thermal

expansion. Means (such as a properly-sized expansion

tank) shall be provided to control thermal expansion.

Contact the water supplier or local plumbing inspector

on how to control this situation.

4B.1 Water System Piping —

Water Heater

Hot water piping should be supported by suitable

hangers or ﬂoor stands. Do not support piping with

this appliance. Due to expansion and contraction of

copper pipe, consideration should be given to the type

of hangers used. Rigid hangers may transmit noise

through the system resulting from the piping sliding in

the hangers. It is recommended that padding be used

when rigid hangers are installed.

4B.3 Water Flow Requirements —

Water Heater

In a water heating application (an open system),

new water is constantly being introduced. With the

new water comes a fresh supply of minerals that can

be deposited on the unit’s heat exchanger. This is

commonly known as scaling. The amount of minerals

will depend upon the hardness of the water. Water can

also be aggressive, and can erode metals, including

copper, if the water is moved too quickly. The water

ﬂow requirements for the Brute Deluxe water heater

are based upon the hardness of the water. The water

ﬂow is kept high enough to prevent scaling, but low

enough to prevent tube erosion. For extremely soft or

hard water, cupro-nickel tubes are available. Contact a

Bradford White representative if you have questions or

concerns about water quality.

The Brute Deluxe can be used with several

different types of readily available storage tanks. A

pump draws water from the storage tank and pumps

the water through the heater and back into the tank.

Pump-mounted units have a circulating pump built

into the water heater. The pumps used are sized for

the head loss through the heater, plus 30 feet (9.1 m)

of full-sized piping (same size as boiler outlet) and

a normal number of ﬁttings. Pumps used on pump-

mounted unit are sized for soft/normal or hard water,

so make sure a pump-mounted unit matches the water

quality of the installation.

Pipe the outlet from the heater’s relief valve

such that any discharge from the relief valve will be

conducted to a suitable place for disposal when relief

occurs. Do not reduce line size or install any valves in

this line. The line must be installed to allow complete

drainage of both the valve and the line.

Pump-mounted water heaters can be ordered

with standard pumps for soft or normal water or with

pumps for hard water. The pumps used are sized for

the head loss through the heater, plus 30 feet (9.1m)

of full-sized piping (same size as heater outlet) and a

normal number of ﬁttings.

Suggested piping diagrams are shown in Figures

9, 10, 11 and 12. These diagrams are meant only as a

guide. Components required by local codes must be

properly installed.

Table 9 speciﬁes water ﬂow rates for water

heaters, which will enable the user to size a pump. The

head loss shown is for the heater only, and the user

will need to add the head loss of the piping system to

properly size the pump.

Note the recommended location of the

temperature sensor on the diagrams. The Brute Deluxe

is shipped with an additional sensor that can be used

for more full-featured domestic water heating control.

To get these features, you must provide a location for

the additional sensor. It can be strapped to a pipe from

1" to 4" diameter, or inserted into a tank immersion

well.

4B.4 Combined Water Heating (potable)

and Space Heating — Water Heater

NOTE: These systems are not allowed in the

Commonwealth of Massachusetts.

The minimum inlet water temperature for the

Brute Deluxe is 120°F (49°C) to avoid condensing on

the copper coils.

Piping and components connected to this water

heater for the space heating application shall be

suitable for use with potable water.

Toxic chemicals, such as used for boiler

treatment, shall not be introduced into the potable

water used for space heating.

This water heater when used to supply potable

water shall not be connected to any heating system

or component(s) previously used with a non-potable

First, shut off the manual gas valve, and call

the unit for heat. After the pre-purge and ignitor

heat-up time, the main gas terminals will be

energized, attempting to light, for seven (7)

seconds, and then will de-energize. The unit will

attempt to light two more times, and then will go

into lockout mode. Second, turn the power off

and then on again, open the manual gas valve

and allow the unit to light. While the unit is

operating, close the manual gas valve and ensure

that power to the main gas valve has been cut.

16. Within three (3) days of start-up, recheck all air

bleeders and the expansion tank as described in

Steps 4 and 8 above.

SECTION 6.

Operating Instructions

6.1 Filling the Boiler System

1. Ensure the system is fully connected. Close all

bleeding devices and open make-up water valve.

Allow system to ﬁll slowly.

2. If make-up water pump is employed, adjust

pressure switch on pumping system to provide

a minimum of 12 psi (81.8 kPa) at the highest

point in the heating loop.

3. If a water pressure regulator is provided on the

make-up water line, adjust the pressure regulator

to provide at least 12 psi (81.8 kPa) at the highest

point in the heating loop.

Important: The installer is responsible for identifying

to the owner/operator the location of all emergency

shutoff devices.

4. Open bleeding devices on all radiation units

at the high points in the piping throughout

the system, unless automatic air bleeders are

provided at such points.

5. Run system circulating pump for a minimum of

30 minutes with the boiler shut off.

6. Open all strainers in the circulating system,

check ﬂow switch operation, and check for

debris. If debris is present, clean out to ensure

proper circulation.

WARNING

Do not use this appliance if any part has been

under water. Immediately call a qualified service

technician to inspect the appliance and to replace

any part of the control system and any gas control

that may have been under water.

AVERTISSEMENT

N’utilisez pas cet appareil si l’une de ses pièces est

passée sous l’eau. Appelez tout de suite un technicien

en entretien et en réparation pour inspection de

l’appareil et remplacement des pièces du système de

commande, et des pièces de commande du circuit

gaz, qui sont passées sous l’eau.

7. Recheck all air bleeders as described in Step 4.

8. Check liquid level in expansion tank. With the

system full of water and under normal operating

pressure, the level of water in the expansion tank

should not exceed ¼ of the total, with the balance

ﬁlled with air.

9. Start up boiler according to the procedure in this

manual. Operate the entire system, including the

pump, boiler, and radiation units for one (1) hour.

10. Recheck the water level in the expansion tank. If

the water level exceeds ¼ of the volume of the

expansion tank, open the tank drain, and drain to

that level.

11. Shut down the entire system and vent all

radiation units and high points in the system

piping, as described in Step 4.

12. Close make-up water valve and check strainer in

pressure reducing valve for sediment or debris

from the make-up water line. Reopen make-up

water valve.

13. Check gauge for correct water pressure and also

check water level in the system. If the height

indicated above the boiler insures that water is at

the highest point in the circulating loop, then the

system is ready for operation.

6.2 Operating Temperature Control

(Note: BMT2 may be ordered with either an on/

off or 2-stage aquastat.)

To utilize the boiler's on-board controller, be sure

to have the “Local/Remote” selector switch to “Local”.

Set the controller to the desired operating set point.

The controller has an interstage differential that can be

adjusted from 3°F to 10°F. This allows the user to have

some control over how stage 2 and stage 1 call for heat

(see Figure 19).

Because the Brute Deluxe controller senses inlet

water and the manual reset high limit senses outlet

water, the high limit should be set 40-50°F higher than

the controller, to avoid nuisance lockout of the manual

reset high limit.

6.3 External Boiler Operations

If controlling the stages of the BMT2 from an

external source (multiple boiler control, BAS, etc) the

“Local/Remote” selector switch above the terminal

strip must be placed in the “Remote” position. In this

mode, the controller that is mounted on the BMT2

will no longer have control of the unit. The 24V from

the unit waits at the input terminal, and the external

14. Refer to local codes and the make-up water

valve manufacturer’s instructions as to whether

the make-up water valve should be left open or

closed.

15. After placing the unit in operation, the ignition

system safety shutoff device must be tested.

If the airﬂow proving circuit is not proven,

ignition module will lock out. Section 6.5 describes

the result of air ﬂow faults in more detail.

When the ignition control gets the signal at the

PSW terminal, it will energize its MV terminal, which

sends power to the stage one (or on/off) main valve.

After a 7-second trial for ignition, the ignitor

switches to ﬂame sense mode. If a ﬂame is not

detected, the gas valve will close and the ignition

module will attempt ignition again (up to two more

times, for a total of three attempts.) If all three

attempts fail, the ignition control will lock out.

If ﬂame is sensed, the burner will continue to

ﬁre as long as there is a call for heat, and none of the

safety circuit is interrupted.

If there is a call for stage 2 on a 2-stage unit, that

valve will be energized.

If there is a loss of ﬂame signal during a

successful ﬁring sequence, the ignition control will

remove power from the gas valves, and then attempt

to light up to two more times. If successful, the Brute

Deluxe will ﬁre normally. If unsuccessful, the ignition

control will lock out.

*1 Difference between the temperatures at which the two switches

make R-W. Adjustable from 3°F to 10°F (1.7°C to 5.6°C) on standard

models, or from 3.6°F to 12°F (2.0°C to 6.7°C); 55°F to 175°F (13°C

to 79°C) models.

When the call for heat is satisﬁed, the gas

valve(s) closes, and the blower starts a 45 second post-

purge. Any pump connected to the Brute Deluxe pump

time delay relay will continue to run for the time delay

period (dialed by the user, 0.1 to 10 minutes).

*2 Two DPDT switches operate in sequence. Each switch

differential is fixed at approximately 3°F (1.7°C) on standard models,

or 3.6°F (2.0°C); 55°F to 175°F (13°C to 79°C) models.

Figure 19. Honeywell L8008G.

6.5 Ignition Control Reaction to Air Flow /

control switches this 24V from the input terminal to

the stage terminal. The input for stage 1 is initiated

by closing the circuit between the 2 terminals on the

terminal strip labeled "input stage 1." The input for

stage 2 is initiated by closing the circuit between the 2

terminals on the terminal strip labeled "input stage 2."

Blocked Vent Pressure Switch

Air ﬂow and blocked vent status are continuously

monitored by the Brute Deluxe ignition control, at the

control’s PSW terminal.

At the start of an ignition sequence, if the ignition

control sees power at PSW for 30 seconds, but the

combustion blower has not yet been energized by the

control (F1 and F2). The ignition control will remain

in this fault mode, with the blower off. If the power to

PSW is removed while there is still a call for heat, the

ignition sequence will start again, but the main valves

will not be energized until PSW sees power during the

ignition sequence.

At the start of an ignition sequence, the control

sends the combustion blower output (F1 and F2). If

the control does not see power at PSW for more than

30 seconds, the control will remain in this fault mode,

with the blower on. If proper airﬂow is later detected

on PSW, the control begins a pre-purge and a normal

trial for ignition.

6.4 Sequence of Operation

The pump time delay relay will receive a signal

to initiate. If the unit is pump-mounted, the pump

will be energized. The pump terminals on the ﬁeld-

wiring terminals strip will energize a ﬁeld pump that is

properly interlocked with the Brute Deluxe.

Once the water ﬂow switch makes, if all of the

safety interlocks are closed, the ignition module will

energize the blower(s) for a 15-second pre-purge,

followed by a 40-second period to allow the ignitor to

heat.

The ignition control energizes the blower. The

blower pressurizes the air box (which supplies air to

the burners) and closes the normally-open contact

on the airﬂow pressure switch. The blocked vent

pressure switch senses the pressure in the exhaust

plenum. This switch opens if the pressure is excessive

(as an indicator of a blocked vent). When these two

pressure switches are closed, voltage is sent to the

PSW terminal on the ignition control, which allows the

ignition module to proceed with the ignition sequence.

If the PSW signal is lost while the Brute Deluxe

is ﬁring, the control will immediately de-energize the

gas valve terminal (MV). The blower will remain on

for the post-purge period (45 seconds), and the control

will continue to monitor the PSW input. If the signal

is detected during the post-purge period, a normal trial

for ignition will begin, starting with the 15-second

pre-purge. If the signal is not detected during the post-

purge, the control will lockout with the blower off.

appliance. The ignition sequence will

start again and the burner will start. The

appliance will return to its previous mode

of operation.

6.6 Operating the Burner and Set-Up

6.6.1 Set-Up for 0 to 2500 Feet Altitude

The setup must be checked before the unit is put

in operation. Problems such as failure to start, rough

ignition, strong exhaust odors, etc. can be due to

improper setup. Damage to the Brute Deluxe resulting

from improper setup is not covered by the limited

warranty.

6.6.2 High Altitude Adjustment and

Set-Up

1. Using this manual, make sure the installation

is complete and fully in compliance with the

instructions.

2. Determine that the appliance and system are

ﬁlled with water and all air has been bled from

both. Open all valves.

3. Observe all warnings on the Operating

Instructions label and turn on gas and electrical

power to appliance.

4. Switch on the appliance power switch located on

the right side of the unit.

5. The Brute Deluxe will enter the start sequence,

as long as the unit is being called for heat. The

blower and pump come on for pre-purge, then

the ignitor warm-up sequence starts and after

the ignitor warm-up is complete and all safety

devices are veriﬁed, the gas valves open. If

ignition doesn’t occur, check that there is proper

gas supply. Wait 5 minutes and start the unit

again. During initial start up, air in the gas line

may cause the Brute Deluxe to "lock out" during

the ﬁrst few trials for ignition. If the ignition

control locks out, reset by cycling the power off

and on using the main power switch on the right

side of the cabinet.

High altitude adjustment must not be made on

appliances operating at elevations below 2500 ft. (762 m).

No oriﬁce changes are required to adjust the

Brute Deluxe appliances for high altitude. High

altitude adjustment is accomplished by adjustment

of the air shutter. A CO₂or O₂analyzer is required to

make these adjustments.

Start the adjustment process by checking the CO₂

in the “as installed” condition. Adjust the air shutter(s)

so that the CO₂is about 8% or the O₂is about 6.8%

for appliances operating on natural gas. For appliances

operating on LP Gas adjust the air shutter(s) so that the

CO₂is about 9.2% or the O₂is about 6.8%.

If the appropriate CO₂/ O₂levels cannot be

achieved by adjusting the air shutter. Contact the

Technical Services Department at number shown on

back page.

The amount of derate will vary depending on

heating value of the fuel and the elevation at the

installation site.

Caution

Should any odor of gas be detected, or if the gas

burner does not appear to be functioning in a

normal manner, close main shutoff valve, do not

shut off switch, and contact your heating contractor,

gas company, or factory representative.

6. When the unit is running, the supply gas pressure

must be checked. Inlet gas pressure must not

exceed 13 in. w.c. (3.2 kPa). The minimum inlet

gas pressure is 5 in. w.c. (1.2 kPa) and 8 in. w.c.

(2 kPa) for LP.

Attention

7. Once the inlet gas pressure is veriﬁed, the

outlet gas pressure from each valve (manifold

gas pressure) must be checked, and adjusted, if

necessary. The manifold gas pressure must be 3.0

in. w.c. (0.62 kPa) for natural gas and 9.0 in. w.c.

(2.2 kPa) for LP.

8. Complete the setup by checking the CO₂at the

outlet of the unit. The CO₂should be 8% for

natural gas, or 9.2% for LP.

required, per the instructions on the pump.

2. If a strainer is employed in a pressure reducing

valve or the piping, clean it every six months.

3. Inspect the venting system for obstruction or

leakage at least once a year. Periodically clean

the screens in the vent terminal and combustion

air terminal (when used).

4. Keep the appliance area clear and free from

combustible materials, gasoline, and other

ﬂammable vapors and liquids.

5. If the appliance is not going to be used for

extended periods in locations where freezing

normally occurs, it should be isolated from the

system and completely drained of all water. All

systems connected to it should also be drained or

protected from freezing.

1. Switch off the main electrical disconnect switch.

2. Close all manual gas valves.

3. WAIT FIVE (5) MINUTES.

4. Set the aquastat or thermostat to its lowest

setting.

5. Open all manual gas valves.

7.2.1 Burners

Close main manual gas valve before proceeding.

Checking the burners for debris - Remove the ignitor/

burner access panel and ignitor, and inspect the

burners through the ignitor hole using a ﬂashlight to

illuminate. If there is any indication of debris on the

burners that is visible, all the burners will need to be

inspected more thoroughly. Remove the gas manifold

assemblies and the burner assemblies. Inspect the

burners. Clean burners, if necessary, by blowing

compressed air from the outside of the burners into

the center of the burner. A dirty burner may be an

indication of improper combustion or dirty combustion

air. Determine the cause, and correct. Replace the

burners in the reverse order.

7.2.5 Ignition Control

The ignition control controls the hot surface

ignitor and proves that the ﬂame signal is appropriate

for powering the gas valves. It also controls the

blower’s pre-purge and post-purge.

To replace a control, shut off the 120-volt power

to the appliance. Remove the cover from the control

panel. Remove the electrical connectors from the

ignition control. Take out the controller’s mounting

screws, and pull the controller out. Replace in reverse

order.

7.2.6 Ignitor

The ignitor used is a 120v “Hot Surface” type.

It is energized whenever there is a call for heat and

switched off when ignition is established and the ﬂame

has been sensed. To replace the ignitor, shut off the

120-volt power to the appliance, remove the ignitor/

burner access panel, disconnect the Molex connector,

remove the two mounting screws on the ignitor ﬂange,

and pull the ignitor out. Install in reverse order, always

using a new ignitor gasket with the replacement

ignitor.

7.2.2 Filter

The ﬁlter used in the Brute Deluxe is washable

and has an 80% arrestance rating. Since the ﬁlter is

washable, it will only need replacement occasionally.

If ﬁlter replacement is needed, it should only be

replaced with a factory part. Inspect the air ﬁlter

monthly, or more often in dirty environments. If there

is debris on the air ﬁlter, remove it from the ﬁlter

frame, and wash it with mild soap and water. Ensure

that the ﬁlter is completely dry before reinstalling.

Caution

Ignitor gets hot. To avoid injury, handle the ignitor

with caution.

7.2.3 Gas Valves

The gas valves are designed to operate with

supply pressures of 4-13 in. w.c. (1.0 to 3.2 kPa).

To remove a valve, shut off 120-volt power

and the manual gas shutoff valve. Remove the front

panels from the unit. Disconnect the wires to the valve.

Disengage the unions before and after the valve, and

remove the valve. Pull the pipe nipples from the inlet

and outlet of the valve, and clean the threads on the

pipe nipples for reuse. Apply new tape or pipe dope

to the pipe nipples (threaded joints should be coated

with piping compound resistant to action of liqueﬁed

petroleum gas), and reinstall in reverse order. Turn

on manual gas shutoff valve and 120 volt power and

check appliance operation and tightness of gas valve

connections.

outlet.

6. Allow the heat exchanger to drain. Remove the

venting and remove the top, by removing the

screws that attach the top to the side panels.

Remove the side panels.

7. Remove the heat exchanger from the unit.

NOTE: Heat exchangers are heavy and may

require two people to remove to avoid personal

injury.

8. Clean the heat exchanger: A light accumulation

of soot or corrosion on the outside of the heat

exchanger can be easily removed. Use a wire

brush to remove loose soot and scale from the

heat exchanger.

9. NOTE: While the heat exchanger is out of the

unit, inspect the ﬁrewall refractory insulation.

Replace if necessary.

10. Inspect the inside of the copper tubes for scale

buildup. Scale can build up on the inner surface

of the heat exchanger tubes, which can restrict

water ﬂow. If the tubes show signs of scaling,

clean the internal surface.

11. Reassemble in the reverse order, and check

appliance operation after start-up.

Caution

Water may be hot enough to scald. Allow water to

cool before proceeding.

Attention

L’eau peut être chaude au point de vous brûler.

Laissez refroidir l’eau avant d’intervenir.

Release pressure in the system by actuating

the pressure relief valves or ﬁeld supplied boiler

drain valve. Remove cover from the ﬂow switch

and disconnect the wires. Unthread the ﬂow switch

from piping. Ensure the new ﬂow switch paddles are

trimmed to the same size as the original paddles, and

reinstall in the reverse order. For boiler and other static

pressure systems, restore the system pressure to the

original setting, (or 10 psi minimum).

7.2.9 Heat Exchanger Coil

WARNING

NOTE: The warranty does not cover damage

caused by lack of required maintenance, lack of

water flow, or improper operating practices.

Black carbon soot buildup on a dirty heat exchanger

can be ignited by a random spark or flame thereby

creating a risk of fire or explosion. To prevent this

from happening, dampen the soot deposits with a

wet brush or fine water spray before servicing the

heat exchanger.

AVERTISSEMENT

L’accumulation de suie sur un échangeur thermique

sale peut s’enflammer au contact d’une étincelle ou

d’une flamme et présenter un risque d’incendie ou

d’explosion. Afin d’empêcher que cela se produise,

humidifier les dépôts de suie à l’aide d’une brosse

mouillée ou par une pulvérisation fine d’eau avant

d’effectuer l’entretien de l’échangeur thermique.

The Brute Deluxe has a premixed burner system.

These systems provide the burners with sufﬁcient air

for complete combustion, and black carbon sooting is

seldom experienced. If sooting is suspected, view ports

for inspection of the heat exchanger are provided on

the side of the boiler. In the unlikely event that there is

a buildup of black carbon soot or other debris on the

heat exchanger, clean per the following:

1. Disconnect the electrical supply to the unit.

2. Turn off the gas supply by closing the manual gas

a load distribution problem. If the set points are correct

and the system design, controls scheme, etc. are ﬁxed,

the temperature differentials may be increased to

reduce short cycling. If desired temperature response

is not achievable without short cycling it may be

necessary to install a buffer tank in the system. Contact

your Bradford White representative to discuss possible

remedies.

SECTION 8.

Trouble Shooting

8.1 Resolving Lockouts

There are many causes of lockouts. The three

most common causes are: (1) inadequate gas supply,

(2) poor combustion, (3) ignitor failure.

1. Inadequate gas supply: Before proceeding, ensure

that the gas supply has not been shutoff or the LP

tank (LP boilers) is not empty. Then, restart the

boiler and observe the operational cycle. After

a 15-second fan pre-purge, the ignitor will heat

up for 40 seconds, and then the unit will light.

If it does not, check the gas supply pressure to

the appliance, after resetting the appliance and

attempting another start-up. The gas pressure to

the appliance must be above 5 in. w.c. (1.2 kPa)

throughout the entire start-up cycle. If it is not,

correct the supply problem (check gas valves or

supply piping). If the supply pressure is adequate,

consult the factory for assistance.

2. Poor Combustion: Poor combustion should be

suspected if there is a strong ﬂue gas odor. The

odor may result from an improper gas/air ratio

(high or low O₂or CO₂). Brute Deluxe appliances

operate best with 45% excess air (8% CO₂on

natural gas, 9.2% CO₂on LP). Check the CO₂of

the appliance and adjust if necessary.

8.4 Short Cycling — Water Heater

Short cycling will generally occur only in

combination space heating and water heating

applications when the water heater is operating in the

space-heating mode. If the heating load drops below

the minimum input of the water heater for an extended

period, the water heater will have a tendency to short

cycle. If short cycling is frequently experienced,

regardless of the control’s attempt to limit it, the

heating load should be redistributed to control it.

If short cycling occurs in a water heater

application, it is probably caused by undersized

piping between the water heater and the storage tank

or by some other factor that restricts proper water

ﬂow through the water heater. The cause should be

determined and corrected.

8.5 High Gas Consumption

Appliances operating with an improper air/

fuel ratio are very inefﬁcient and consequently, have

very high gas consumption. Because efﬁciency is

high when the CO₂is high (or O₂is low), appliances

operating with low CO₂or high O₂(especially LP

appliances) consume more gas. Adjust the CO₂or O₂

for optimum efﬁciency. If no combustion analyzing

equipment (CO₂or O₂) is available then a proper

adjustment of the air/fuel ratio (CO₂or O₂) cannot be

accomplished. The CO₂should be 8% at high ﬁre for

natural gas and 9.2% at high ﬁre for LP. To check the

CO₂, ﬁrst verify that the supply gas pressure is within

5 to 13 in. w.c. (1.2 to 3.2 kPa). With the Brute Deluxe

running with all stages ﬁring, set the air box pressure

to 1.8 in. w.c. (0.42 kPa) (as a starting point), by

adjusting the air shutter(s) at the intake of the fan(s).

Check the CO₂, and adjust the air shutters if further

adjustment to the CO₂is needed.

3. Ignitor failure: If the boiler goes through a

normal start cycle but combustion does not

occur, ignitor failure should be suspected. Check

the ignitor by unplugging the ignitor plug and

measuring the ignitor resistance. It should be

50-80 ohms. If the resistance is not 50-80 ohms,

replace the ignitor. If the resistance is correct,

reset the boiler and check for 120 VAC at the

ignitor plug during the start cycle. If there is no

voltage, replace the faulty ignitor wire harness or

the ignition control.

8.2 Delayed Ignition — Possible Causes

A defective burner can cause a delayed ignition.

If the gas supply pressure is proper and the gas

valves are functioning properly, then burners should

be inspected. There should be no distortion or

perforations in the burners outside of the active burner

port area. Replace if indicated.

8.3 Short Cycling — Boiler

Boiler short cycling is caused when the load

on the boiler system swings rapidly causing frequent

cycling between call for heat and satisﬁed conditions.

This condition is greatly reduced on two stage units

or stage controlled multiple boiler systems which can

change heat input to better match the load. If short

cycling is a problem, it may be due to an oversized

boiler, improper control strategy, incorrect set points or
