DANGER

WARNING

liQUEFiED PETROlEUm mODElS — Propane, or lP gas,

gasoline, as well as other flammable materials and liquids

(adhesives, solvents, etc.), and the vapors they produce,

are extremely dangerous. DO NOT handle, use or store

gasoline or other flammable or combustible materials any-

where near or in the vicinity of a water heater. Be sure to

read and follow the warning label pictured below and other

labels on the water heater, as well as the warnings printed

in this manual. Failure to do so can result in property dam-

age, bodily injury, or death.

must be used with great caution.

• it is heavier than air and will collect first in lower areas

making it hard to detect at nose level.

•

make sure to look and smell for lP leaks before

attempting to light appliance. Use a soapy solution to

check all gas fittings and connections. Bubbling at a

connection indicates a leak that must be corrected.

When smelling to detect an lP leak, be sure to sniff

near the floor too.

• gas detectors are recommended in lP applications

and their installation should be in accordance with the

manufacturer's recommendations and/or local laws,

rules, regulations or customs.

DANGER

• it is recommended that more than one method be used

to detect leaks in lP applications.

Failure to properly vent the water heater to the outdoors

as outlined in the Venting Section of this manual can result

in unsafe operation of the water heater. To avoid the risk

of fire, explosion, or asphyxiation from carbon monoxide,

never operate this water heater unless it is properly vented

and has an adequate air supply for proper operation. Be

sure to inspect the vent system for proper installation at

initial start-up; and at least annually thereafter. Refer to

maintenance section of this manual for more information

regarding vent system inspections.

iF lP gAS iS PRESENT OR SUSPECTED:

• DO NOT attempt to find the cause yourself;

• DO NOT try to light any appliance;

• DO NOT touch any electrical switch;

• DO NOT use any phone in your building.

• leave the house immediately and make sure your fam-

ily and pets leave also.

• leave the doors open for ventilation and contact the

gas supplier, a qualified service agency or the fire

department.

• Keep the area clear until the service call has been

made, the leak is corrected, and a qualified agency has

determined the area to be safe.

D A N G E R

WARNING

Both lP and natural gas have an odorant added to help

detection. Some people may not physically be able to

smell or recognize this odorant. if unsure or unfamiliar

about the smell associated with lP or natural gas, ask the

gas supplier. Other conditions, such as "Odorant Fade",

which causes the odorant to "fade", or diminish in inten-

sity can also hide or camouflage a gas leak.

FLAMMABLES

WARNING

alcoves. The minimum side and top clearance to walls and ceiling for

providing protection of combustible materials are shown on the water

heater’s rating label. A front clearance of 18 inches (46 cm) should be

provided for adequate inspection and servicing.

Read and Review this entire manual with special emphasis

on the Venting Sections (Pages 8-12) and Operation Section

(Pages 14-17) prior to any installation work.

LOCAL INSTALLATION REGULATIONS

If the water heater must be installed on carpeting, place a metal or

wood panel beneath water heater extending beyond its full width and

depth at least 3 inches (7.6 cm) in all directions. If the water heater is

installed in an alcove, the entire floor must be covered by the panel.

The water heater should not be located in an area where leakage of

the tank or connections will result in damage to the area adjacent

This water heater must be installed in accordance with these instructions,

local codes, utility company requirements and/or, in the absence of local

codes, the latest edition of the National Fuel Gas Code, ANSI Z223.1 in

the United States, or CGA/CAN B149 Installation Codes in Canada.

LOCATION

A. This water heater is of the direct vent design. All air for combustion

and all products of combustion are routed through the venting system,

directly from and to the outside of the building.

CAUTION

to it or to lower floors of the structure.When such areas cannot be

avoided, it is recommended that a suitable catch pan, adequately

drained, be installed under the water heater. The pan mUST NOT

restrict the flow of combustion air flow to bottom of water heater.

The water heater should be installed in a clean, dry location as close

as practical to the gas vent terminals. Long hot water lines should be

insulated to conserve water and energy. The water heater and water

lines should be protected from exposure to freezing temperatures.

NOTICE: Auxiliary catch pan installation MUST conform to the ap-

plicable local codes.

B. A gas fired water heater should not be installed in a space where liquids

which give off flammable vapors are to be used or stored. Such liquids

include gasoline, LP gas (butane and propane), paint or adhesives and

their thinners, solvents or removers. Because of natural air movement

in a room or other enclosed space, flammable vapors can be carried

some distance from where their liquids are being used or stored. The

open flame of the water heater’s intermittent pilot or main burner can

ignite these vapors causing an explosion or fire which may result in

severe burns or death to those in range, as well as property damage.

For these reasons, installation of a gas fired water heater in a garage

is not desirable.

D. RESTAURANTS — If the water heater is to be installed in a restau-

rant or other location where the floor is frequently cleaned, it must be

elevated to provide at least six inches (15 cm) of clearance from the

floor to comply with NSF International recommendations.

E. CORROSIVE ATMOSPHERES — The heater should not be installed

near an air supply containing halogenated hydrocarbons. For example,

the air in beauty shops, dry cleaning establishments, photo processing

labs, and storage areas for liquid and powdered bleaches or swim pool

chemicals often contain such hydrocarbons.The air there may be safe

to breathe, but when it passes through a gas flame, corrosive elements

are released that will shorten the life of any gas burning appliance.

Propellants from common spray cans or gas leaks from refrigeration

equipment are highly corrosive after passing through a flame.The lim-

ited warranty is voided when failure of water heater is due to a corrosive

atmosphere. (Refer to the Certificate of Limited Warranty for complete

terms and conditions.)

WARNING

if a location in a garage is the only alternative, the gas water heater

should be installed so that the open flame of the pilot and main

burner are no less than 18 inches above the garage floor.The water

heater must be located or protected so it is not subject to physical

damage by moving vehicles or area flooding. Raising the gas fired

water heater will reduce BUT NOT eliminate the possibility of light-

ing the vapor of any flammable liquids which may be improperly

stored or accidentally spilled.

installation

heater. If special instructions are required for any specific water heater,

they will be included in the bag.

WARNING

Cap or plug unused connections. Use only clean, new galvanized steel,

copper or approved plastic pipe for water connections. Local codes

or regulations shall govern the exact type of material to be used. The

installation of unions on the inlet and outlet water lines and a shut-off

valve in at least the cold water inlet line is recommended, so the water

heater may be easily disconnected for servicing. Dielectric unions are

not required for protection of water heater.

The manufacturer’s warranty does not cover any damage or defect

caused by installation, or attachment, or use of any special attach-

ment such as energy saving devices (other than those authorized

by the manufacturer) into, onto, or in conjunction with the water

heater. The use of such unauthorized devices may shorten the

life of the water heater and may endanger life and property. The

manufacturer disclaims any responsibility for such loss or injury

resulting from the use of such unauthorized devices.

When this water heater is supplying general purpose hot water require-

ments for use by individuals, a thermostatically controlled mixing valve

is recommended to reduce the risk of scald injury. Contact a licensed

plumber or the local plumbing authority for further information.

1. INSPECT SHIPMENT — for possible damage. The manufacturer’s

responsibility ceases upon delivery of goods to the carrier in good

condition. Any claims for damage, shortage in shipments, or non de-

livery must be filed immediately against carrier by consignee.

Thermometer(s) should be installed so that they indicate the tempera-

ture of the water at or near the outlet of the water heater and storage

tank(s) if provided. See Fig. 4 on page 7.

2. THERMAL EXPANSION — Determine if a check valve exists in the

inlet water line. It may have been installed in the cold water line as a

separate back flow preventer, or it may be part of a pressure reduc-

ing valve, water meter or water softener. A check valve located in

the cold water inlet line can cause what is referred to as a ”closed

water system”. A cold water inlet line with no check valve or back

flow prevention device is referred to as an ”open” water system.

3. RELIEF VALVE — A new factory installed combination pressure and

temperature relief valve, complying with the Standard for Relief Valves

and Automatic Gas Shutoff Devices for Hot Water Supply Systems,

ANSI Z21.22, or Standard CAN1-4.4, Temperature, Pressure, Tempera-

ture and Pressure Relief Valves and Vacuum Relief Valves is provided

with the water heater. No valve is to be placed between the relief valve

and the water heater. For a circulating tank installation, the separate

storage tank(s) must have similar protection.The pressure rating of the

relief valve must not exceed 150 psi (160 psi for ASME models), the

maximum working pressure as marked on front of the water heater.

As water is heated, it expands in volume and creates an increase

in the pressure within the water system. This action is referred to as

”thermal expansion”. In an ”open” water system, expanding water

which exceeds the capacity of the water heater flows back into the

city main where the pressure is easily dissipated.

The Btu/h rating of the relief valve must equal or exceed the Btu/h input

of the water heater as marked on its rating plate.

A ”closed water system”, however, prevents the expanding water

from flowing back into the main supply line, and the result of ”thermal

expansion” can create a rapid, and dangerous pressure increase in

the water heater and system piping.This rapid pressure increase can

quickly reach the safety setting of the relief valve, causing it to oper-

ate during each heating cycle. Thermal expansion, and the resulting

rapid, and repeated expansion and contraction of components in the

water heater and piping system can cause premature failure of the

relief valve, and possibly the heater itself. Replacing the relief valve

will not correct the problem!

Connect the outlet of the relief valve to a suitable open drain. The

discharge line must pitch downward from the valve to allow complete

draining (by gravity) of the relief valve and discharge line, and be no

smaller than the outlet of the valve. The end of the discharge line

should not be threaded or concealed and should be protected from

freezing. No valve of any type, restriction or reducer coupling should be

installed in the discharge line. Local codes shall govern the installation

of relief valves.

4. GAS SUPPLY — The inlet gas pressure to the water heater must not

exceed 10.5” w.c. (2.6 kPa) for Natural gas. For purposes of input adjust-

ment, the minimum inlet gas pressure (with main burner on) is shown on

the rating plate. Check to see if high or low gas pressure is present and

then contact the gas company for correction.

The suggested method of controlling thermal expansion is to install an

expansion tank in the cold water line between the water heater and the

check valve.The expansion tank is designed with an air cushion built in

that compresses as the system pressure increases, thereby relieving

the over pressure condition and eliminating the repeated operation of

the relief valve. Other methods of controlling thermal expansion are also

available. Contact your installing contractor, water supplier, or plumbing

inspector for additional information regarding this subject.

The gas line should be of adequate size to prevent undue pressure

drop. Sizing based upon Table 1 (on pg. 13) is recommended. No ad-

ditional allowance is necessary for an ordinary number of fittings.

A ground joint union and manual shutoff valve should be installed in

the gas line near the water heater so that the burner assembly may

be easily removed. The shut-off valve must be readily accessible for

turning on or off. See Fig. 4 on page 7.

If a recirculation line is installed, the return connection should be made

to a tee close to the inlet connection on the water heater. A check valve

should always be installed in the recirculation line to prevent cold water

from entering.

A sediment trap must be installed at the bottom of the gas line. See

Fig. 4 on page 7.

WATER CONNECTIONS — This water heater may be connected indi-

vidually, in multiples with others, or with an external hot water storage

tank.

LEAK TESTING — The water heater and its gas connections MUST

be leak tested at normal operating pressure before it is placed in op-

eration. Turn ON the manual gas shut-off valve near the water heater.

Use a soapy water solution to test for gas leaks at all connections and

fittings. Bubbles indicate a gas leak that must be corrected.The water

heater factory connections to the gas valve should also be leak tested

after placing the water heater in operation.

Inlet water connections are made to the lower coupling on the heater,

and outlet water connections are made to the upper coupling.

Each water heater is supplied with the necessary components (Diffuser

tubes) to make the water connections that will ensure proper perfor-

mance. The components are supplied in a bag attached to the water

The unit may be vented horizontally through a wall or vertically through

WARNING

the roof. Pipe runs must be adequately supported along both vertical

and horizontal runs. Maximum unsupported span is recommended to

be no more than 4 feet. It is imperative that the first hanger be located

on the horizontal run immediately adjacent to the first 90-degree elbow

from the vertical rise or at the blower outlet in the case of a horizontal

blower position. Support method used should isolate the vent pipe from

floor joists or other structural members to help prevent the transmission

of noise and vibration. Do not support, pin or otherwise secure the vent-

ing system in a way that restricts the normal thermal expansion and

contraction of the chosen venting material.

NEVER use open flame to test for gas leaks, as bodily injury or

property damage could result.

PRESSURE TESTING THE GAS SUPPLY SYSTEM — The water

heater and its manual gas shut-off valve MUST be disconnect-

ed from the gas supply piping system during any high pressure

testing of that system at pressures in excess of 1/2 psi

(14” w.c. / 3.5 kPa).

The water heater MUST be isolated from the gas piping system

by closing the manual gas shut-off valve during any pressure test-

ing of the gas supply piping at pressures equal to or less than

1/2 psi (14” w.c. / 3.5 kPa).

If the water heater is being installed as a replacement for an existing

power vented water heater, a thorough inspection of the existing venting

system must be performed prior to any installation work. Verify that the

correct materials, as detailed above have been used, and that the mini-

mum or maximum vent length and terminal locations as detailed in this

manual have been met. Carefully inspect the entire venting system for

any signs of cracks or fractures, particularly at the joints between elbows

or other fittings and the straight runs of vent pipe. Check the system for

signs of sagging or other stresses in the joints as a result of misalignment

of any components in the system. If any of these conditions are found,

they must be corrected in accordance with the venting instructions in this

manual before completing the installation and putting the water heater

into service.

5. VENTING —

Vent Pipe Connection locations

The blower assembly is preinstalled at the factory, so all that is required

for connecting the vent system is attaching the vent pipe to the blower

and the PVC Tee. Before starting the vent installation, careful planning

should be given to the routing and termination of the vent pipe.The length

of the vent pipe (inlet and outlet) should be kept to a minimum. Also, see

page 10 & 12 for vent terminal placement.The GP100-150 & GP100-200

model can be vented using either 3 inch or 4 inch Schedule 40 PVC pipe

and fittings.

NOTICE: This unit can be vented using only the following

recommended pipe material. Use only 3- or 4-inch diameter pipe.

PVC (Schedule 40, ASTM D-1785)

CPVC (Schedule 40, ASTM F-441)

ABS (Schedule 40, ASTM D-2661)

To use 3 inch PVC, you can connect directly to the blower outlet (rubber

coupling provided for outlet connection) and PVC Tee. Make sure that

clamps on rubber coupling are tight, after the pipe is installed. The inlet

vent pipe should be cemented into the PVC Tee.

The fittings, other than the VENT TERMINAL, should be equiva-

lent to the following:

PVC (Schedule 40 DWV, ASTM D-2665)

CPVC (Schedule 40 DWV, ASTM F-438)

ABS (Schedule 40 DWV, ASTM D-2661)

If 4 inch PVC pipe is going to be used, then it will be necessary to have

a short piece ( at least 3 inches long ) of 3 inch PVC pipe to join into the

coupling and tee. Then a 4 X 3 reducer would need to be joined to the

short piece of pipe, so that the 4 inch pipe could be used.The 4 inch pipe

will then need to be stepped back down, using a 4 X 3 reducer, to 3 inch

PVC. To install the vent terminals, a short length of 3 inch (maximum of

16 inches long) pipe will need to be used. (Refer to Figure 9b on page

10.)

The GP100-250 model can only be vented using 4 inch Schedule 40 PVC

pipe and fittings. The 4 inch pipe can be connected directly to the blower

coupling and 4 inch tee.

Not Allowed

1 In accordance with current CAN/CGA-B149 Installation Codes.

2 In accordance with current ANSI Z223.1/ NFPA 54 National Fuel Gas Code.

+ A vent shall not terminate directly above a sidewalk or paved driveway that is located between two single family dwellings and serves both dwellings.

* If clearances are not specified then follow local installation codes and the requirement of the gas supplier.

DRAINING THE CONDENSATE – In certain conditions,

installations in unconditioned space or having long horizontal or vertical

runs may accumulate condensate. In order to prevent condensate from

draining back into the blower, we recommend that it be drained. This

unit is provided with a special fitting on the blower that allows for the

draining of condensate formed in the vent. The drain hose should have

two (2) loops formed, to act as traps. Before operation of the water

heater, both loops should have water placed in them. Support the traps

so that they remain horizontal. Condensate is known to be acidic; refer

to local, state or federal codes for proper handling methods.

PVC materials should use ASTM D-2564 grade cement.

CPVC materials should use ASTM F-493 grade cement.

ABS materials should use ASTM D-2235 grade cement.

Cleaner-Primer and Medium Body Solvent Cement

1. Cut pipe end square, remove jagged edges and burrs. Cham-

fer end of pipe, then clean fitting socket and pipe joint area

of all dirt, grease or moisture.

2. After checking pipe and socket for proper fit, wipe

socket and pipe with cleaner-primer. Apply a liberal coat of

primer to inside surface of socket and outside of pipe. Do not

allow primer to dry before applying cement.

3. Apply a thin coat of cement evenly in the socket. Quickly

apply a heavy coat of cement to the pipe end and in-

sert pipe into fitting with a slight twisting motion until it

bottoms out.

NOTICE: Cement must be fluid; if not, recoat.

Figure 10 - Draining the Condensate

4. Hold the pipe fitting for 30 seconds to prevent the tapered

socket from pushing the pipe out of the fitting.

JOINING PIPES AND FITTINGS – All pipe, fittings, solvent

cement, primers and procedures must conform to Ameri-

can National Standards Institute and American Society for

Testing and Materials (ANSI/ASTM) standards.

5. Wipe all excess cement from the joint with a rag. Allow 15

minutes before handling. Cure time will vary according to fit,

temperature and humidity.

NOTICE: Stir the solvent cement frequently while using. Use

a natural bristle brush or the dauber supplied with the can.

The proper brush size is one inch.

CEMENTING JOINTS – All joints in the vent piping must

be properly sealed and we recommend using the following mate-

rial:

FOR PROPER iNSTAllATiON:

Avoid skin or eye contact. Observe all cautions

and warnings on material containers.

CAUTION

6. WIRING — A polarized 120V 50/60 Hz power supply, with suitable

disconnect means, must be connected to the black and white leads

provided. The current draw by the Power Direct Vent unit is 1.5 Amps.

The water heater, when installed, must be electrically grounded in ac-

cordance with local codes, or, in the absence of local codes, with the

National Electrical Code, ANSI/NFPA 70 in the United States; or CSA

C22.1 Electrical Code, in Canada. Refer to Fig. 14 on page 26 & 27

of this manual for water heater internal wiring diagrams.

• DO NOT use solvent cement that has become

curdled, lumpy or thickened.

• DO NOT thin solvent cement. Observe shelf

precautions printed on the containers.

• For applications below 32°F use only low

temperature type solvent cement.

• Appropriate solvent and cleaner must be used for

the type of vent pipe used (PVC, CPVC or ABS).

NOTICE: DO NOT use in conjunction with a GFCI.

CAUTION

hydrogen gas can be produced in a hot water system served by

this water heater that has not been used for a long period of time

(generally two weeks or more). hYDROgEN gAS iS ExTREmElY

FlAmmABlE!!To dissipate such gas and to reduce risk of injury,

it is recommended that the hot water faucet be opened for several

minutes at the kitchen sink before using any electrical appliance

connected to the hot water system. if hydrogen is present, there

will probably be an unusual sound such as air escaping through

the pipe as the water begins to flow. Do not smoke or use an

open flame near the faucet at the time it is open.

D. Do Not store or use gasoline or other flammable vapors and liquids,

such as adhesives or paint thinner, in vicinity of this or any other

appliance. If such flammables must be used, open doors and win-

dows for ventilation, and all gas burning appliances in vicinity should

be shut off, including their pilot lights, to avoid vapors igniting.

NOTICE: Flammable vapors may be drawn by air currents from sur-

rounding areas to the water heater.

2. TEMPERATURE SETTINGS — The thermostat is adjusted to its lowest

temperature position when shipped from the factory. To meet com-

mercial water use needs, it is adjustable up to 180°F (82°C). How-

ever, water temperatures over 125°F (52°C) can cause severe burns

instantly or death from scalds. This is the preferred starting point for

setting the control for supplying general purpose hot water.

WARNING

When this water heater is supplying general purpose hot water

requirements for individuals, a thermostatically controlled mixing

valve for reducing point of use water temperature is recommend-

ed. Contact a licensed plumber or the local plumbing authority for

further information.

Safety and energy conservation are factors to be considered when

setting the water temperature on the thermostat. The most energy ef-

ficient operation will result when the temperature setting is the lowest

that satisfies the needs consistent with the application.

Outlet water temperature will vary during normal operating cycles. Reli-

able temperature readings should be taken shortly after main burner

cycles off during a period of little or no use.

hotter water increases the Potential for hotWater SCAlDS.

3. GAS MANIFOLD PRESSURE — With the gas valve supplied with this

water heater, main burner ignition occurs at a low or step manifold

pressure, which will then automatically build up to its normal operat-

ing level .The rated operating manifold pressure is listed on the water

heater rating plate. For purposes of input adjustment, the minimum inlet

gas pressure(with main burner on) is also shown on the rating plate.

A 1/8” NPT tapping is provided on the outlet side of the gas valve for

connecting a manometer to check this pressure. If necessary, adjust

the pressure to the proper value by turning regulator adjustment screw

clockwise to increase pressure or counterclockwise to decrease pres-

sure.

DANGER

4. CHECK INPUT — Consult the local Gas Company to determine the

heating value of the gas supplied. Check input by clocking gas meter with

all other gas appliances turned off. Use the following formula:

To adjust the water temperature, insert a small straight

screwdriver into slotted screw in hole in front of ther-

mostat and turn wheel to desired setting. Thermostat

is adjustable up to 180º F.

the clocked time is at least 60 seconds.

Small adjustments can be made by varying the manifold pressure from

the designated settings mentioned above.

WARNING

Should overheating occur or the gas supply fail to shut off, turn off

the manual gas control valve to the appliance.

5. INTERMITTENT PILOT FLAME ADJUSTMENT — No adjustment is

required with normal inlet gas pressures. The pilot flame adjustment

valve is pre-set, and does not normally require re-adjustment.

WARNING

6. HIGH ALTITUDE — Ratings of gas appliances are based on installation

and operation at sea level of elevations of 2000 feet.

DO NOT use this appliance if any part has been under water. imme-

diately call a qualified service technician to inspect the appliance

and to replace any part of the control system and any gas control

which has been under water.

Factory prepared high altitude models are available and are specifically

rated for installation at elevation up to 8000 feet. Refer to rating plate

on the front of the water heater for number and altitude specifications.

Also refer to the supplement sheet for information on venting high

altitude models.

If the water heater has been subjected to fire or physical damage, turn

off gas at the manual gas control (shut-off) valve. Do not operate the

water heater again until it has been checked out by a qualified service

technician.

maintenance

Properly maintained, this water heater will provide years of dependable,

trouble free service. It is strongly suggested that a regular routine main-

tenance program be established and followed by the owner. It is further

recommended that a periodic inspection of the blower, thermostat, burner,

relief valve, internal flueway, draft hood / damper assembly and venting

system should be made by service technicians qualified in gas appliance

repair.

TO REMOVE BURNERTRAY:

1. Turn off manual gas shut-off valve.

2. Disconnect gas pipe union and wiring to gas valve and pilot.

3. Remove retaining screws from plate on the same side as the gas

valve.

4. Slide burner tray assembly out. When reinstalling the burner tray

assembly, make certain it is pushed in all the way so that the plate

lines up with the holes in the plenum side.Then reinstall the retain-

ing screws.

1. ROUTINE PREVENTIVE MAINTENANCE

A. BURNERS — Visually inspect the main burner flame and the pilot flame

at least every three months. Refer to Figures 12 and 13 for normal

flame pattern. Fallen scale can usually be dislodged from the tops of

the burners with a thin rod, then vacuumed or brushed from the bottom

of the burner box. If a more thorough cleaning is deemed necessary

to restore a normal flame pattern, the burner tray assembly should be

removed and the burners cleaned individually.

5. Reconnect gas pipe union and wiring to gas valve and pilot, turn

on manual gas shut-off valve and test for gas leak.

B. VENTING SYSTEM — Inspect venting system at least yearly to make

certain the passageways are free and unobstructed, and that the vent

connector from the water heater’s blower assembly is properly posi-

tioned and securely attached. Remove any obstructions in vent con-

nector or vent terminal.

CAUTION

C. CONTROLS — The manifold pressure and controls should be checked

at least yearly by a qualified service technician.

For your safety, removal and cleaning of burner tray and individual

burners should be performed ONlY by a qualified service techni-

cian, as it involves disconnection of gas piping and leak testing.

maintenance

D. BLOWER — Clean the blower periodically to remove any buildup of

lint or dirt. Remove the inlet plate and blow out any lint or dirt on the

wheel and on the screen of the inlet plate. Before operation, re-install

the inlet plate to the blower.

A wet-dry shop vac with a nozzle fashioned from 1” and/or 3/4” poly-

ethylene pipe makes a good tool for scraping and removing scale.

TO CLEAN OR INSPECT TANK:

1. Shut off gas valve and drain tank.

E. PRESSURE SWITCH — Inspect the inlet to the pressure switch and

the tubing for debris or blockage. Clean out the tubing periodically to

prevent buildup of debris.

2. Remove tank clean-out cover on jacket and with pocket knife cut

and remove a circular plug of insulation the full size of jacket open-

ing.

F. EMERGENCY CUT-OFF — This water heater is equipped with a com-

bination thermostat/temperature limiting device (ECO) that should be

checked annually by qualified service personnel.

3. Loosen nut on seal plate assembly enough to twist yoke sideways.

Hold assembly securely and push inward, then remove from tank.

G. THERMAL CUTOFF SWITCH — Some units are equipped with a

thermal cutoff switch which will shut down the unit if the flue gas tem-

perature is above permissible limits. The switch is a manual reset

type.

4. Remove as much built-up scale from flue tubes and tank bottom as

practical. Do not attempt to clean so thoroughly that the tool used

damages the glass lining.

CAUTION

5. Clean the seal plate and install a new gasket. Wipe clean the inte-

rior surface of the tank that contacts the gasket. Reinstall the seal

plate and tighten in position. Fill tank with water and check for leaks.

If no leaks are found, install insulation plug and clean-out cover on

jacket and re-light the water heater.

label all wires prior to disconnection when servicing controls.Wir-

ing errors can cause improper and dangerous operation.

VERiFY PROPER OPERATiON AFTER SERViCiNg!

If chemical lime dissolving cleaners are preferred, cautiously follow

the instructions supplied with the cleaner. DO NOT use a muriatic or

hydrochloric acid (HCl) base cleaner.

G. RELIEF VALVE — The Temperature and Pressure Relief Valve must

be free to operate properly. Check (at least once a year) by lifting the

handle fully and allowing several gallons of water to flush through the

discharge line. Make certain the discharged water is directed to a

suitable drain.

2. ANODE INSPECTION — The water supply in certain areas contains

very aggressive elements. In these areas, periodic inspection of the

anode is recommended to determine if replacement is necessary.The

anode(s) supplied in this water heater is slowly consumed , thereby

eliminating or minimizing corrosion and protecting the glass lined tank.

The anode(s) should be replaced when more than 6 inches (15 cm) of

core wire is exposed at either end.

DANGER

Before manually operating the relief valve, make certain no one

will be exposed to the danger of coming in contact with the hot

water released by this valve.The water may be hot enough to cre-

ate a SCAlD hazard. The water released should be directed to a

suitable drain to prevent injury or damage.

3. SEASONAL OPERATION — If the water heater is to remain idle for an

extended period (60 days or more) the heater should be turned off.The

water heater and piping should be drained if they might be subjected

to freezing temperatures. It is recommended that the water heater’s

operation is thoroughly checked (by a qualified service technician)

before it is placed back in service. NOTICE: Refer to Hydrogen Gas

caution notation on page 16.

NOTICE: If the temperature and pressure relief valve on the water

heater discharges periodically, this may be due to thermal expansion

in a “closed” water system. Contact the water supplier or local plumbing

inspector on how to correct this. DO NOT plug the relief valve outlet.

H. TANK— Good maintenance requires that the tank be cleaned of de-

posits. Unless the water supply is soft (0 to 5 grains hardness), scale

or lime deposits will accumulate in the tank. Hard water scale is de-

posited at an increasingly high rate in proportion to increased water

temperature. Accumulation of these deposits may reduce efficiency,

and shorten the life of the water heater.

Any new installation should have a tank inspection program set up

initially for frequent inspection. The first inspection should be within a

six month period. Once the scaling tendencies have been established,

the inspection program can be modified to suit the water conditions.

Cleaning should be performed if the scale has accumulated above the

drain valve opening.

“System Sentinel” Diagnostic System

The “System Sentinel” Diagnostic system on this water heater provides the user or service technician with a visual representation of the

operational status of the various sections of the water heater’s control system. A quick glance at the System Sentinel panel on the front of

the heater will give an indication of where to begin trouble shooting of a non operational heater.

The LED’s (light emitting diodes) on the panel are arranged from top to bottom based on their function in the normal sequence of operation,

and their function is explained as follows:
