INTRODUCTION
THIS IS A GAS-FIRED, GRAVITY VENTED ROOM HEATER THAT WILL OPERATE SAFELY AND PROVIDE AN EFFICIENT
SOURCE OF HEAT WHEN INSTALLED, OPERATED AND MAINTAINED AS RECOMMENDED IN THESE INSTALLATION
AND OPERATING INSTRUCTIONS. READ THESE INSTRCTIONS THOROUGHLY BEFORE INSTALLING, SERVICING, OR
USING THIS APPLIANCE. IF YOU DO NOT UNDERSTAND ANY PART OF THESE INSTRUCTIONS, CONSULT LOCAL
AUTHORITIES, OTHER QUALIFIED INSTALLERS, SERVICE AGENCIES, THE GAS SUPPLIER, OR THE MANUFACTURER.
VENTING
This heater must be connected to a properly installed and maintained venting system. This heater is equipped with a vent safety
shut-off device. Pilot outage will occur if the heater is not connected to a vent system. Pilot outage may occur due to restriction or
blockage in the vent or if connected to a masonry chimney having an area greater than the vent size shown on Page 2.
This appliance should be vented through a properly sized listed type B vent that has been constructed in accordance with the
National Building Code. If a horizontal section of vent is used, it must slope upwards a minimum of ¼ inch per foot of length.
This heater must not be connected to a vent system being used for wood or coal burning appliances. The use of more than one
appliance per vent system will most likely cause the vent safety shut-off device to shut off the heater due to the cooling of vent
temperatures through the draft diverter of the second appliance. In some situations, the vent safety shut-off may shut down the
heater if a too large, unlined, masonry chimney is used. Due to low vent temperatures associated with more efficient heaters it may
take too long to get the vent action going in a chimney before the shut-off device will shut down the heater. If this is the case, we
recommend lining the chimney with the proper size type B vent pipe or type B chimney liner.
WARNING: Do not bypass the vent safety shutoff switch. To do so could expose the consumer to
property damage, personal injury or possible death.
The switch, when activated, will extinguish the pilot flame. If the homeowner experiences this problem, the vent system must be
checked and corrected. NOTE: An existing vent that has worked for years may not be adequate for todays design because of
higher efficiency requirements resulting in lower stack temperatures. The following is a list of possible causes and corrective
actions.
POSSIBLE CAUSES
1. Blockage in vent pipe
CORRECTIVE ACTION
1.A)
1.B)
Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc.
Check that the vent cap is properly installed, not shoved too far down on the vent
pipe.
2. Burner is over firin
2.A)
2.B)
Check the manifold pressure.
Check the rate, NOTE: This appliance was orificed for elevations up to 2,000 feet.
When installed at higher elevations refer to orifice chart in main burner orifice
section of instructions for proper orifice size and re-orifice accordingly.
3. Improper vent system
A) Vent too short
3.
Correct vent system.
A)
The vent should not terminate less than 5 feet above the drafthood connection. A
gas vent extending through an exterior wall shall not terminate adjacent to the
wall or below eaves or parapets. Also, the top of the vent must be at least 2 foot
above any obstacles within a 10 foot radius, including the roof. See Figure A.
All type “B” vent shall extend in a generally vertical direction with offsets not
exceeding 45 degrees, except that a vent system having not more than one 60
degree offset may be allowed. Any angle greater than 45 degrees from the vertical
is considered horizontal. The total horizontal run of a vent plus the horizontal vent
connector shall be not greater than 75 percent of the vertical height of the vent.
Any offsets used should be as far above the drafthood as possible to allow a
venting action to begin before any restriction is encountered.
B) Restriction in vent
system caused by
offsets
B)
C) Incorrect vent pipe
C)
4.
Use listed “B” type vent pipe. Do not use transite or any other type of ceramic
pipe for venting. Do not use single wall pipe.
4. Loose connections on the
vent safety wiring harness
Check the connection on both the switch and the gas valve. Tighten if necessary.

PILOT ADJUSTMENT
MAIN BURNER ORIFICE
This appliance was shipped from the factory with an orifice
sized to give the correct gas input using the gas for which the
heater was equipped. There may be local conditions, such as
variation in gas pressure or BTU content of the gas, which
may be cause for a change in the orifice. The gas company
supplying the fuel or the installing contractor should check
the gas input rate.
The pilot flame can be observed by opening the pilot lighting
hole cover. The pilot flame should surround the top 3/8 to ½
inch of the thermocouple (see Figure 2). If the flame needs
adjusting, first locate the pilot adjustment screw cap and remove.
Adjustment screw is underneath (see Figure 1). To increase the
flame, turn the pilot adjustment screw counterclockwise
.
To decrease the flame, turn the screw clockwise . NOTE:
If the rate exceeds the “BTUH INPUT” on the rating plate by
5%, the orifice should be replaced with a smaller orifice by a
qualified technician to reduce the input to the rating plate
value.
The pilot is unregulated. If incoming line pressure is more than
7” w.c. Natural Gas or 11” w.c. for L.P. Gas, the pilot flame size
should be decreased.
The input rate may need to be adjusted for elevation. See the
following charts to determine the correct orifice size for your
Model Number and elevation. These orifice sizes are based
on a heating value of 1020 for Natural Gas and 2500 for L.P.
Gas.
CAUTION: As elevation increases, derating is necessary for
the safe and proper operation of this heater. Do not increase
the Btu input rate by increasing the orifice size or gas
pressure. Allow for elevation derating when sizing gas heating
equipment.

MAINTENANCE
CAUTION: There may be momentary and spasmodic
orange flashes in the flame. This is caused by the burning
of air borne dust particles and is not to be confused with
the yellow tipping which is a stable or permanent situation
when there is insufficient primary air.
CLEANING: To clean the front casing of your heater, it is
only necessary to use a soft cloth. Light dust can be removed
in this way. To obtain a polish or gloss, use a little light
machine oil on the cloth. Do not use metal polish or cleaning
solution. The burner ports should be kept free from lint and
dust.
PROPER BURNER FLAME
CLEANING OF COMBUSTION CHAMBER

SERVICE RECORD
8. Clean the rear chamber by using bottlebrush
through the vent tube openings.
9. Replace combustion chamber, burner and control.
Check all gas piping for leaks before lighting heater.
Repair service should be performed by qualified persons.
The heater should be inspected before initial use. An annual
cleaning of control compartment and safety performance
check should be made by a qualified service person. More
frequent cleaning may be required when exposed to the
excessive lint conditions due to carpeting and bedding
material, etc. It is imperative that the control compartment,
burners, and circulating air passageways of the heater be
kept clean. Any safety screen, casing top, or guard removed
for servicing the heater must be replaced prior to operating
heater.
If the venting system is not maintained in proper operating
condition, the vent safety shutoff will not allow heater to
operate. Periodic examination of the entire venting system
as a routine part of the safety performance check is
recommended on an annual basis.
It is advised that the pilot and main burner flames be checked
at least twice during the heating season for any changes in
flame characteristics. See Figure 2 and Figure 3.
THIS IS A GAS-FIRED APPLIANCE, KEEP THE AREA CLEAR OF GASOLINE AND OTHER FLAMMABLE
VAPORS AND LIQUIDS. ALL COMBUSTIBLE MATERIAL MUST BE KEPT CLEAR OF THIS AREA.

STEP 1. Run black wire and white wire that comes from bottom of junction box down through the heat shield. See Figure A.
STEP 2. Insert junction box into opening in back of heater. Attach using four #8x1/2” black screws provided. See Figure A.
STEP 3. Attach fan switch to fan switch bracket using two #8x1/2” plated, Phillip head screws provided. The 2” flange on the
bottom of bracket and terminals on the fan switch should be toward the back of the heater when properly installed.
STEP 4. Locate the two engagement holes in base of heater. On a 35,000 Btu heater these holes are approximately 6-1/2” from the
back edge and right and left holes are 5-1/4” and 7-1/4” respectfully from the right side (as viewed from back of heater). On
a 50,000 Btu heater the holes are approximately 10-3/4” from the back edge and right and left holes are 5-3/8” and 7-3/8”
respectfully from the right side. Attach fan switch bracket to base using two #8x1/2” hex head screws provided. This will
require a ¼” socket and ratchet. See Figure A.
STEP 5. Locate the blower opening and mounting tab on the base of the heater. Insert the front flange of the blower housing under
the mounting tab, lower the back of the blower down onto the base aligning the clearance holes in the blower base with the
engagement holes in the heater base. Secure the blower to the base with two #8 screws provided. See figure A.
STEP 6. Connect black wire from junction box to right fan switch terminal. See Figure B.
STEP 7. Connect white wire from junction box to white fan motor wire. See Figure B.
STEP 8. Connect black wire from fan motor to left fan switch terminal. See Figure B.
STEP 9. Turn variable speed control switch clockwise
STEP 10. Plug power cord into 115 V. grounded receptacle.
STEP 11. Turn variable speed control switch counterclockwise
(as viewed from front of unit) to “OFF”.
(as viewed from front of unit) from “OFF” to “HIGH”. Blower
will now cycle on automatically when the switch temperature is met after the main burner comes on. The blower will
continue to run for a short period after the main burner goes off. Blower speed can be adjusted by setting the variable
speed control switch between high and low.
WARNING: This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this
plug.

IMPORTANT SAFETY BULLETIN ON YOUR GAS CONTROL AND PILOT LIGHT
SYSTEM FOR HEATING EQUIPMENT
WHAT YOU DON’T KNOW CAN HURT YOU.
Your pilot light system has been designed for safe and reliable operation. Although safety mechanisms
are built-in, the potential for hazard exists. This information is intended to help you avoid these hazards.
YOUR GAS CONTROL AND PILOT LIGHT
SYSTEM
WHAT TO DO IF YOU SMELL GAS . . .
•
Do not try to light any appliance.
Do not touch any electrical switch; do not use
any phone in your building.
Your gas control and pilot light system has a
safety device whose purpose is to shut-off the
gas supply to the appliance if the pilot light goes
out. If you have trouble lighting the pilot or
keeping it lit, it may mean that this safety device
is warning you that there is a problem with your
system. Inspection and repairs or replacement

•
Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
If you cannot reach your gas supplier, call the
fire department.
must be made by a trained gas service technician.
Installation and service must be performed by a
qualified installer, service agency or the gas
supplier.
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
CRITICAL SAFETY POINTS TO REMEMBER
. . .
TAMPERING IS DANGEROUS
The pilot safety system may also not work if you
do not follow the lighting instructions carefully
or if you tamper with the gas control that you use
to light the pilot. Tampering with the gas control,
particularly with tools, can damage the safety
mechanism in the control and can allow gas to
leak. This can result in a fire or explosion causing

floor level.
property damage, personal injury or death.
IF YOU SMELL GAS, DON’T LIGHT IT
•
•
If you smell gas, do not attempt to light the
pilot. Do not cause a spark by turning on or off
electrical switches or appliances or by using the
phone. Turn off the gas to the appliances and
call your gas supplier from another location.
If your gas control has gotten wet as the result
of flooding or other wetting, it must be replaced
immediately by a trained gas service technician.
Water can lead to damage of the internal safety
mechanism in the gas control and can create a
hazardous condition.
IF YOU CAN’T LIGHT IT,
DON’T FIGHT IT!
