GENERAL INFORMATION
This heater is a self-contained two stage infrared radiant tube heater for use in locations where flammable gases or
vapors are not generally present (as defined by OSHA acceptable limits) and is intended for the heating of
nonresidential spaces.
INSTALLATION REQUIREMENTS
The installation must conform to local building codes or in the absence of local codes, with the National Fuel Gas
Code ANSI Z223.1/NFPA54 or the Natural Gas and Propane Installation Code CSAB149.1. Heaters shall be installed
by a licensed contractor or licensed installer. Clearances to combustibles as outlined in this manual should always
be observed. In areas used for storage of combustible materials where they may be stacked below the heater,
NFPA54 requires that the installer must post signs that will “specify the maximum permissible stacking height to
maintain the required clearances from the heater to combustibles.”

Every heater shall be located with respect to building construction and other equipment so as to permit access to the
heater. Each installer shall use quality installation practices when locating the heater and must give consideration to
clearances to combustible materials, vehicles parked below, lights, overhead doors, storage areas with stacked
materials, sprinkler heads, gas and electrical lines and any other possible obstructions or hazards. Consideration also
must be given to service accessibility.
The heater, when installed in aircraft hangars and public garages, must be installed in accordance with ANSI/NFPA
409-latest edition (Standard for Aircraft Hangars), ANSI/NFPA 88a-latest edition (Standard for Parking Structures),
and ANSI/NFPA 88b-latest edition (Standard for Repair Garages) with the following clearances:
a. At least 10 feet above the upper surfaces of wings or engine enclosures of the highest aircraft that may be
housed in the hangar and at least 8 feet above the floor in shops, offices, and other sections of hangars
communicating with aircraft storage or service areas.
b. At least 8 feet above the floor in public garages. ꢀWARNING: Minimum clearances marked on the heater must
be maintained from vehicles parked below the heater.
(FOR CANADA ONLY)
a. Installation of this appliance is to be in accordance with latest edition of CAN 1-B149.1 (Installation Code for
Natural Gas Burning Appliances and Equipment), and/or CAN B149.2 (Installation Code for Propane Gas Burning
Appliances and Equipment).
b. For installation in public garages or aircraft hangars, the minimum clearances from the bottom of the infrared
heater to the upper surface of the highest aircraft or vehicle shall be 50 percent greater than the certified
minimum clearance, but the clearance shall not be less than 8 feet.
Although these heaters may be used in many applications other than space heating (e.g., process heating), Space-
Ray will not recognize the warranty for any use other than space heating.
This heater is for Indoor Installation and Covered Patio Installation only and can be used in either Vented or Unvented
mode. The term Unvented actually means Indirect Vented. While the products of combustion are expelled into the
building, national codes require ventilation in the building to dilute these products of combustion. This ventilation
may be provided by gravity or mechanical means.
This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point
materials exists, it could result in property damage or death. This heater must not be installed in a spray booth where
the heater can operate during the spraying process. Consult your local fire marshal or insurance company.
PTS Series Only: Since straight tube heaters are always hotter at the control end than at the flue terminal end,
always observe the minimum recommended mounting heights shown on the specification sheets and in Section
5.0 of this manual. Use U-tube configuration instead of straight tubes for spot or area heating (e.g., where a single
heater is utilized for space heating).

High Altitude:
Appliances are supplied as standard for altitudes of O to 2,000 feet (0-610 m). High-altitude ratings are obtained
by a change in the orifice size. When ordered for high altitude installations, burners are supplied by the factory
ready for high altitude installation. Check the nameplate for altitude before proceeding with the installation. In
Canada the adjustment for altitude is made in accordance with Standard CGA 2.17, Gas-Fired Appliances for Use
at High Altitudes.

* When used indirect vented, minimum clearance for CEILING must be: 12” for PTS/PTU 50-75 and 18” for
PTS/PTU 100-200. If optional corner and u-bend reflectors are not used, the clearance must be 18”.
** Maximum clearance below reduces to 72” once you are 20ft. downstream from the control box.
ꢀWARNING: Certain materials or objects, when stored under the heater, will be subjected to radiant heat and
could be seriously damaged. Observe the Minimum Clearances to Combustibles listed in the manual and on the
heater at all times.
NOTE: The clearances specified above must be maintained to combustibles and other materials that may be
damaged by temperatures 90ºF above ambient temperature. Clearances to combustibles are posted on the
control box. In areas used for storage of combustible materials where they may be stacked below the heater,
NFPA54 requires that the installer must post signs that will “specify the maximum permissible stacking height to
maintain the required clearances from the heater to combustibles.” Space-Ray recommends posting these signs
adjacent to the heater thermostat or other suitable location that will provide enhanced visibility.

TYPICAL SUSPENSION METHODS
SUSPENSION HAZARD
Burner must be secured to the mounting flange with nuts.
All materials used to suspend the heater must have a minimum working load
of 115 lbs.
All “S” Hooks must be crimped closed.
Never use the heater to support a ladder or other access equipment.
Failure to do so may result in death, serious injury or property damage.
Various means of suspending the heater can be used. See the following drawings for typical examples.
1. Use only noncombustible materials for hangers and brackets.
2. A minimum No. 2 chain with a working load limit of 115 lbs. is required.
3. Turnbuckles can be used with chains to allow leveling of the heater. All “S” hooks and eye bolts must be
manually crimped closed by the installer.
4. When using rigid means for heater suspension (rod, flat bar, etc.) provide sufficient lengths or swing joints to
compensate for expansion. See Figures b and c.
5. Heaters subject to vibration must be provided with vibration isolating hangers.
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent
structure with adequate load capacity.
Space-Ray recommends that the body sections be suspended using chains with turnbuckles. This will allow slight
adjustments after assembly and heater expansion/ contraction during operation.
If a “trapeze” method is used (shown below), the minimum chain length for the two connecting chains is 36”. If these
chains must be less than 36”, then do not use the trapeze method and, instead, use individual chains on each tube
support/hanger bracket.

ASSEMBLY OF TUBE SECTIONS
CUT HAZARD
Sheet metal parts, particularly reflectors and vent have sharp
edges. Always use gloves when handling.
Failure to do so may result in death, serious injury or property
damage.
During field assembly of the heater body sections, the recommended procedure is as follows:
1. Before hanging heater sections, first determine the actual layout of the system (see Sections 7.0 & 8.0 for
details). Consideration must also be taken for flue pipe, fresh air ducting, gas piping, clearances to combustibles,
etc. before hanging heater. Typical suspension methods are shown in Section 9.0.
2. Hang each tube section individually. DO NOT attach the heater tube sections together on the ground and attempt
to hang the entire system.
3. In all configurations, the burner box must be connected directly to either a) the 24-hole flange of the 10 ft.
aluminized steel starting body section (for 10 ft., 20 ft., and 30 ft. systems) or b) the 6-hole flange of the 10 ft.
alumi-therm steel starting body section (for 40 ft., 50 ft., 60 ft., and 70 ft. systems.
4. Assemble a tube support/hanger bracket 4” from the end of the heat exchanger tube having the mounting
flange. Align the tube such that the welded seam is facing down toward the ground.
FAILURE TO ASSEMBLE THE TUBE WITH THE SEAM FACING DOWN
WILL VOID THE MANUFACTURER’S WARRANTY.

and then raise the tube support bracket end up to the suspension chain, use “S” hooks to attach the wire hanger
and tube support bracket to the chain.

Join the tube sections together and secure with tube couplings as described below:
ꢀWARNING: THE FOLLOWING COUPLING TIGHTENING INSTRUCTIONS MUST
BE FOLLOWED PROPERLY TO AVOID FUTURE PROBLEMS.
1. Place the compression coupling over the end of the tube.
2. Use the small hole at the centerline of the coupling to check that the coupling is inserted correctly.
3. Partially tighten the bolt nearest the end of the tube (approximately half closed).

9. Once all the heater body sections are attached, make sure that the heater system is level. If it is not, slight
adjustments can be made using the turnbuckles. (See Section 9.0)
IMPORTANT: NEVER REUSE A COUPLING. Always install a new
coupling only and torque as per instructions above and the diagrams
above.
10.2)
INSERTING TURBULATORS
POISONOUS GAS AND SOOT HAZARD
The heater must be assembled with the correct number of turbulator sections
and tube length for the rated heat input.
The turbulator must be installed in the last tube section as shown.
Failure to do so may result in death, serious injury, property damage or illness
from Carbon Monoxide poisoning.
1. Assemble the turbulators together by interlocking the slotted end portions. Slide these into the last tube
section until they are flush with the tube end. Note: Refer to the table below for quantities of turbulators
required for each heater model.

ADDING REFLECTORS
1. Slide the reflectors on the tube support/hanger brackets and through the wire hangers.
2. The tube at the coupling joints must be covered. Slide the reflectors together and provide an overlap of two (2”)
inches for the first reflector overlap after the control unit. All remaining reflector overlaps will be approximately
one (1”) inch. This will allow for the natural expansion and contraction of the heater when in operation. Note: The
heaters can expand and contract up to 1-3/4” of an inch.
3. Secure the reflectors as shown in Detail “A” using #10 x 1/2” self-drilling sheet metal screws at each tube
support/hanger bracket.

GAS CONNECTIONS AND REGULATIONS
Tighten flexible gas hose and components securely.
Flexible metal gas hoses must be installed without any twists or
kinks in them. The hose will move during operation of the heater
and it can crack if it is twisted.
Failure to do so may result in death, serious injury or property
damage.
IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER
1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI
Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation
is made. (In Canada, refer to the latest edition of CAN Standard B.149-1 & -2, Installation Codes for Gas
Burning Appliances and Equipment.)
2. Check that the gas fuel on the burner rating plate matches the fuel for the application.
3. Check that the gas supply piping has the capacity for the total gas consumption of the heaters and any other
equipment connected to the line.
4. Check that the calculated supply pressure with all gas appliances and heaters operating will not drop below
the minimum supply pressure required for these heaters. Check inlet supply pressures on Section 14.
5. All gas supply lines must be located in accordance with the required clearances to combustibles from the
heater as listed on the clearances label of the heater and section 4 of this manual.
6. Pipe joint compounds must be resistant to the action of liquefied petroleum gases.
7. Tube heaters will expand/contract during operation. Where local codes do not prohibit, a CSA or U.L.
approved flexible connector supplied with this heater is required for connections between the rigid piping
and the heater. A union should be installed before the burner box inlet. An approved shut off valve should
be installed within 6 feet of the union.
8. The gas pipe, flexible hose and connections must be self supporting. The gas pipe work must not bear any of
the weight of the heater or any other suspended assembly.
9. This appliance is equipped with a step-opening, combination gas valve. The maximum supply pressure to
the appliance is 14” W.C. or 1/2 P.S.I. If the line pressure is more than the maximum supply pressure, then
a second stage regulator which corresponds to the supply pressure must be used.
10. After all gas connections have been made, make sure the heater and all gas outlets are turned off before
the main gas supply is turned on slowly. Turn the gas supply pressure on and check for leaks. To check for
leaks, check by one of the methods listed in Appendix D of the National Fuel Gas Code.
11. If a 2nd stage regulator is used, the ball valve down stream in the supply line must be closed when purging
the gas lines to prevent gas seeping through it. If initial gas pressure is higher than 14” w.c. the redundant
combination gas valve is designed to lock out. Pressure build-up in the supply lines prior to the heater must
be released before proper heater operation.
DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR
LEAKS.

SUPPLY PRESSURE
1. The installer will provide a 1/8” N.P.T. tapped plug, accessible for test gauge connection immediately upstream
of the gas supply connection to the heater.
MANIFOLD PRESSURE– COMBINATION GAS VALVE IS FACTORY SET
Two-stage valves require that you check and adjust both high and low pressure regulator settings.
1. Turn the gas valve to the “OFF” position. Remove the 1/8” plug from the combination gas valve at the outlet
pressure tap and connect a 1/8” nipple to the tapped hole. Connect the gauge to the nipple. Turn on the gas
supply.
2. Set the heater to operate on high. With the main burner operating, check the full rate (high) burner manifold
pressure using a water manometer. Gauges that measure pressure in pounds per square inch are not accurate
enough to measure or set the manifold pressure. All measurements MUST BE made when this heater and all
other gas burning equipment that is connected to the gas supply system are operating at maximum capacity.
3. The combination gas valve is factory set and should not require adjustment. If high pressure adjustment is
required, remove the pressure regulator adjustment cap. Using a 3/32” hex Allen wrench, turn the inner
adjustment screw for HI pressure clockwise ꢁto increase or counterclockwise ꢂto decrease the gas pressure
to the burner.
4. After high pressure has been checked, check low pressure regulation.
5. Using a 3/32” hex Allen wrench, turn the inner adjustment screw for LO pressure clockwise ꢁ to increase or
counterclockwise ꢂto decrease the gas pressure to the burner.
6. Once high and low pressures have been checked and adjusted, replace pressure regulator adjustment cap.

VENTING
CARBON MONOXIDE HAZARD
Heaters installed in an unvented mode require a minimum ventilation flow of
4 CFM per 1,000 Btu/hr of total installed capacity.
In buildings with airborne contamination such as poultry houses the heater
must be installed with fresh air for combustion.
Failure to do so may result in death, serious injury, property damage or illness
from Carbon Monoxide poisoning.
A. BASIC FLUE VENTING — Venting must comply with the latest edition of the National Fuel Gas Code (ANSI
Z223.1-latest edition) or the authority having jurisdiction. Other venting references are in the equipment volume of
the ASHRAE Handbook.

Vent lengths shown in the table are for horizontal and vertical venting. If a longer length of vertical or horizontal
venting is required contact the manufacturer for assistance with vent sizing.
SINGLE HEATER VENTING
(VERTICAL THROUGH THE ROOF)
1. When venting the heater to outside of building through a roof, use single-wall metal pipe. This is to be
constructed of galvanized sheet metal or other approved noncombustible corrosion-resistant material as
allowed by state or local codes.
2. A vent passing through a combustible roof shall extend through an approved clearance roof thimble.
Double-wall, Type B vent must be used for the portion of the vent system which passes through the roof. An
approved vent cap (Leslie “VersaCap”-Type B or equal) must be attached to end of the flue.
3. The maximum equivalent length of vent pipe should be carefully observed. A safety switch in the heater is
designed to shut the heater off before excessive flue restriction causes bad combustion. Refer to the Vent
Sizing Table for maximum vent lengths and vent pipe diameter.
4. Joints between sections of piping shall be fastened by sheet metal screws or other approved means and
should be sealed to prevent leakage of flue gas into building. Aluminum or Teflon tape suitable for 550ºF
(3M Company tapes 433 or 363) or silicone sealant is recommended.
5. All portions of the vent pipe shall be supported to prevent from sagging (6’ spacing is recommended).
6. When the vent pipe passes through areas where the ambient temperature is likely to induce condensation of
Form #43343530
JJuly 08
–34–
Download from Www.Somanuals.com. All Manuals Search And Download.
the flue gases, the vent pipe should be insulated and a condensation drain should be provided.
7. Minimum clearance for single-wall flue pipe to combustible material shall be 6 inches. This may be reduced
when the combustible material is protected as specified in the National Fuel Gas Code or the authority
having jurisdiction.
8. Single-wall metal pipe shall not originate in any unoccupied attic or concealed space and shall not pass
through any attic, inside wall or concealed space, or through any floor. For the installation of a single-wall
metal pipe through an exterior combustible wall, refer to latest edition of the National Fuel Gas Code or the
authority having jurisdiction.
9. A venting system shall terminate at least 3 ft. above any forced air inlet located within 10 ft.

SINGLE HEATER VENTING
(HORIZONTAL THROUGH SIDEWALL)
When venting the heater horizontally through a combustible outside sidewall, the same requirements listed
previously for venting Vertical Through The Roof apply except as follows:
1. A vent passing through a combustible wall must pass through an approved clearance thimble (Air-Jet #4VT
or Ameri-Vent #4EWT or other thimbles that are listed by a nationally recognized testing agency.
2. An approved vent cap (Breidert-Type L or equal) must be attached to the end of the vent pipe.
NOTE: To minimize problems associated with condensation in long horizontal runs, vent pipe can be insulated.
3. Use the following correction factors to obtain the equivalent length when elbows are used:
c. Subtract 10 ft. for each elbow beyond 15 ft. from the heater.
d. Subtract 15 ft. for each elbow within 15 ft. of the heater.
4. Limit to (2) 90º elbows in the vent system.
5. When venting through a sidewall, the horizontal vent pipe shall fall not less than 1/2 inch per 20 feet from
the start of the vent system to the vent terminal. All portions of the vent pipe shall be supported to prevent

MULTIPLE HEATER VENTING
(CONNECTIONS INTO A COMMON VENT OR MANIFOLD)
Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING except as
follows:
1. The common vent size and total vent height is normally determined by the number of heaters per common
vent, length of horizontal connector runs, and connector rise. Connector lengths should be as short as
possible and have a minimum 1/2 inch per 20 foot fall. Without regard to connector rise and total vent
height due to many possible venting configurations, the following should be observed:
a. Common vent pipe & vent connector diameter should be no less than that shown in the following Vent
Sizing Table.
b. The connector length should be no more than 75% of the vertical portion of vent above the connector.
c. Where possible, use a Y-connector to the common vent.
2. Material for connectors should be constructed of galvanized sheet metal or other approved noncombustible
corrosion resistant material as allowed by state or local codes. All common vent pipe should be double wall,
Type B vent.
3. Avoid unnecessary bends. Limit to two (2) 90º elbows.
4. The entire length of vent connector shall be readily accessible for inspection, cleaning and replacement.
5. Groups of heaters with a common vent must be controlled by a common thermostat.

B. INDIRECT VENTING (UNVENTED HEATERS) — This heater requires ventilation in the building to dilute the
products of combustion and provide fresh air for efficient combustion. Where unvented heaters are used, gravity
or mechanical means shall be provided to supply and exhaust at least 4 CFM per 1,000 Btu/hr input of installed
heaters. Exhaust vents must be located at the highest point above and in the vicinity of the heaters, and the inlet
vents must be located below the level of the heaters. An exhaust hood (Part #42924000) must be placed on the
flue adapter collar located on the end of the last body section when used unvented and must be mounted only in
an downward position as shown.

AIR FOR COMBUSTION
If indoor combustion air is to be supplied for a tightly enclosed area, one square inch of free area opening shall be
provided below the heater for each 1,000 Btu/hr of heater input. Adequate clearances around the air inlet screen
must be maintained at all times. In larger open areas of buildings, infiltration normally is adequate to provide air for
combustion.
17.1)
DIRECT OUTSIDE AIR FOR COMBUSTION
Outside combustion air should be supplied directly to the heater when the building is subject to negative pressure, or
when contaminants or high humidity are present in the building air. These contaminants include paints, solvents,
corrosive vapors or any other foreign particles that may cause damage to the heater or result in poor combustion.
Outside combustion air can be brought directly to the heater by a 4” diameter duct less than 50 ft. long or equivalent
(see table in Section 16). This is attached to the 4” diameter starting collar (supplied with heater). The starting collar
is fitted to the rear of the burner box cabinet as shown below. An approved vent cap must be placed directly on the
end of the outside combustion air inlet pipe. The combustion air inlet should be not less than 3 ft. (0.9m), either
vertically or horizontally, from the flue vent termination. The air intake terminal must be located not less than 1 ft.
(30cm) above grade. It is good installation practice to supply combustion air from the same pressure zone as the
vent outlet. Avoid bringing combustion air to the heater from an attic space. There is no guarantee that adequate
combustion air will be supplied.
If the heater is installed less than 2 ft. from the ceiling, a combustion air inlet kit PN 44129510 must be provided to
allow for expansion/contraction of straight tube heaters (PTS series).
In colder climates, where necessary, insulate the outside combustion air duct. In high humidity applications, the
burner box should be sealed with silicone sealer.

1) Turn on the gas and electrical supply. Rotate the gas valve knob counter-clockwise
2) Set the thermostat to call for heat (high fire). The blower motor will energize.
3) Ignition should occur after the 15-second pre-purge.
to the “ON” position.
4) If the burner fails to light, or flame is not detected during the first trial for ignition (a period of approximately 15
seconds) the gas valve is de-energized and the control goes through an inter purge delay of approximately 60
seconds before another ignition attempt. The control will attempt two additional ignition trials before going into
lockout, and the valve relay will be de-energized immediately. The blower will be turned off following a post-purge
period of approximately 30 seconds.
5) If the heater does not light, manually reset the thermostat or shut off power completely for 5 minutes before
attempting to relight.
6) CAUTION: The heater must be grounded. Poor grounding will give nuisance lockouts, particularly during
momentary power interruptions.
7) When the thermostat is satisfied with high heat, the heater will switch to low fire.
8) To shut off the heater, rotate the gas valve knob clockwise
to the “OFF” position and turn off the gas at the
manual gas shut off valve supplying the heater and disconnect the electrical supply.
NOTE: THE LIGHTING AND SHUTDOWN INSTRUCTIONS ARE ALSO SHOWN ON THE PERMANENT NAMEPLATE LABEL

CLEANING AND MAINTENANCE
ELECTRIC SHOCK & EXPLOSION HAZARD
Disconnect electrical power and gas supply before
servicing.
Failure to do so may result in death or serious injury.
This heater must be cleaned and serviced annually by a qualified contractor before the start of each heating season
and at any time excessive accumulation of dust and dirt is observed. Maximum heating efficiency and clean
combustion will be maintained by keeping the heater clean.
The contractor shall check the following during periodic maintenance.
•
•
•
•
Clearances to combustibles: Check that clearances are being maintained. Make sure there are no flammable
objects, liquids or vapors near the heater. See also Section 4.
Reflectors: Reflectors should be kept clean, at a minimum blow off the reflectors. (Dirty reflectors will reduce heat
output).
Heat exchanger tubes: Inspect the heat exchanger tubes to make sure they are not cracked, sagging or showing
signs of fatigue.
Combustion air intake: Disconnect combustion air intake from the burner box and inspect internally using a
flashlight to make sure no foreign material has collected in the tubes and that there is no obstruction around the
air intake openings. Clean any foreign materials. Inspect any joints to make sure they are completely sealed. See
also Section 17.
•
•
•
Venting System: Disconnect vent pipe and inspect internally using a flashlight to make sure no foreign material
has collected in the pipes. Check the external vent cap and make sure that there is no obstruction around the
exhaust openings. Clean any foreign materials. Inspect any joints to make sure they are completely sealed. See
also Section 16.
Gas lines: Make sure that the gas lines are not leaking. Check the gas connection to the heater for any signs of
damage, fatigue or corrosion. If there are any signs of damage to the gas connection or leaks found in the gas
piping, immediately stop using the heater until the gas pipe and connections have been repaired or replaced.
Check that the gas lines are not bearing the weight of the heater. See also Section 13.
Burner Box: In order to extend the longevity of the heater, the heat exchanger tube and the burner must be level.
Check that the burner box is level, use the turnbuckle on the burner suspension eyebolt to adjust the level of the
burner. See also Section 9.
•
•
•
Burner sight glass: Check that the burner sight glass is clean and that the glass is sealed against the housing
door. If there any signs of distortion, the sight glass must be replaced. See section 20 for sight glass location.
Blower wheel and housing: Check that the blower wheel spins freely, blow out any dust or dirt with compressed
air. See section 20 for blower location.
Electrode condition: Visually check that the electrode gap is maintained at 1/8” and that the tips of the flame
sensor and spark electrode are free from deposits. Clean off any deposits. Check that the electrode ceramic is
free from cracks. See Section 23.1
•
Suspension system: Check that the suspension system is holding the heater level. Make sure that the heater is
hanging securely, look for any evidence where the heater may have been hit accidentally and tighten any loose
hanging points. Check that S hooks are closed. Check that there is no evidence of wear on the chain at the
connection to the heater and at the ceiling.
•
•
Tube Integrity Safety System: Check that the tension of the tube integrity safety system is maintained at 11”.
Adjust tension if necessary. See section 12.1

IGNITION SYSTEM CHECKS
TO CHECK FLAME SENSOR CIRCUIT.
Flame current is the current which passes through the flame from the sensor to ground. The minimum flame
current necessary to keep the system from lockout is 0.7 microamps.
a) Turn off heater at thermostat.
b) Connect a meter (dc microammeter scale) in series with the ground lead as shown in the diagram. Connect the
meter as follows:
ꢁ Connect the black (negative) meter lead to the electronic control FC- terminal.
ꢁ Connect the red (positive) meter lead to the electronic control FC+ terminal.
c) Restart the system and read the meter. The flame sensor current must be steady and measure at least 0.7
microamps.
d) If the meter reads less than the minimum or if reading is unsteady:
ꢁ Make sure burner flame is capable of providing a good rectification signal.
ꢁ Make sure fasteners securing igniter/sensor are tightened to assure correct positions. DO NOT relocate
igniter/sensor.
ꢁ Check for excessive (over 1000ºF) temperature at ceramic insulator on flame sensor. Excessive temperature
can cause short to ground. DO NOT relocate igniter/sensor.
ꢁ Check for cracked ceramic insulator, which can cause short to ground, and replace sensor if necessary.
ꢁ Make sure that electrical connections are clean and tight. Replace damaged wire.
e) If the meter reads below “0” on the scale, meter leads are reversed. Disconnect power and reconnect meter
leads for proper polarity.
f) Remove microammeter. Return system to normal operation.
IGNITION MODULE DIAGNOSTICS
Flame Fault
If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will
detect it and energize the combustion blower. Should the main valve later close completely removing the flame
signal, the combustion blower will power off following the post purge period.
