PRODUCT IDENTIFICATION
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce
(30ml) of water for every 1,000 BTUs (.3kWs) of gas input per hour. An unvented room heater is recommended as a
supplemental heater (a room) rather than a primary heat source (an entire house). In most supplemental heat
applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather. The following steps will help insure that water vapor does not
become a problem:
1. Be sure the heater is the proper size for the application, including adequate combustion air and circulation air.
2. If there is high humidity, the dehumidifier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater should not be installed in a confined space or unusually tight construction unless
provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure
proper fresh air for this and other fuel-burning appliances in your home.
PRODUCING ADEQUATE VENTILATION
This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided
by the method described in the NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54, the INTERNATIONAL FUEL
GAS CODE, or applicable local codes.
The following are excerpts from National Fuel Gas Code, NFPA 54/ANSI Z223.1,Section 5.3, Air for Combustion and
Ventilation. All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic
feet per 1,000 BTU per hour (4.8 cubic meters per kw) of the aggregate input rating of all appliances installed in that
space and an unconfining space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8
cubic meters per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating
directly with the space in which the appliances are installed*, through openings not furnished with doors, are
considered a part of the unconfined space.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for
adequate combustion and ventilation air.
Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However,
in buildings of unusually tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one
perm (6x10
-11
kg per pa-sec-m
2
) or less with openings gasketed or sealed and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and
floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air. See “Ventilation Air from
Outdoors” (page 10). If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow
for Heater Location:

8
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or
ventilation grills between the rooms.
1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft. (width) × 8 ft. (ceiling height) =2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the
total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum BTU/hr the space can support.
__________(Volume of space) ÷ 50 cu. ft. = (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space can support)
3. Add the BTU/hr of all fuel burning appliances in the space.
Vent-free heater _____________ BTU/hr
Gas water heater* _____________ BTU/hr
Gas furnace _____________ BTU/hr
Vented gas heater _____________ BTU/hr
Gas heater logs _____________ BTU/hr
Other gas appliances*+ _____________ BTU/hr
Total = _____________ BTU/hr
*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the
outdoors.
4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.
BTU/hr (maximum the space can support)
BTU/hr (actual amount of BTU/hr used).
Example: 51,200 BTU/hr (maximum the space can support)
56,000 BTU/hr (actual amount of BTU/hr used)
The space in the above example is a confined space because the actual BTU/hr used is more than the maximum
BTU/hr the space can support. You must provide additional fresh air. Your options are as follows:
a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space,
remove door to adjoining room or add ventilation grills between rooms. See “Ventilation Air from inside
building”, Page 9.
b) Vent room directly to the outdoors. See “Ventilation Air from Outdoors”, Page 9.
c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconfined. If the actual BTU/hr used is less
than the maximum BTU/hr the space can support, the space is an unconfined space. You will need no
additional fresh air ventilation.
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if
the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods
described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation, or applicable
local codes.
WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion
air, combustion and ventilation air shall be provided by one of the methods described in the NATIONAL FUEL GAS
CODE, ANSI Z223.1/NFPA 54, the INTERNATIONAL FUEL GAS CODE, or applicable local codes.
Example:
Gas water heater 30,000 BTU/hr
Vent-free heater + 26,000 BTU/hr
Total = 56,000 BTU/hr

9
Ventilation Air from Inside Building
This fresh air would come from adjoining
unconfined space. When ventilating to
an adjoining unconfined space, you must
provide two permanent openings: one
within 12 inches of the wall connecting
the two spaces ( see options 1 and 2,
Figure 2 ). You can also remove door
into adjoining room ( see option 3,
Figure 2 ). Follow the National Fuel
Gas Code NFPA 54/ANSI Z223.1. Air
for Combustion and Ventilation for
required size of ventilation grills or ducts.
Ventilation Air from Outdoors
Provide extra fresh air by using ventilation
grills or duct. You must provide two
permanent openings: one within 12 inches
of the ceiling and one within 12 inches of
the floor. Connect these items directly to the
outdoors or spaces open to the outdoors.
These spaces include attics and crawl spaces.
Follow the National Fuel Gas Code NFPA 54/
ANSI Z223.1. Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated
air entering the attic will activate the
power vent. Rework worksheet, adding the
space of the adjoining unconfined space. The
combined spaces must have enough fresh air
to supply all appliances in both spaces.

INSTALLATION
NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating
system. Do not install this heater as your primary heat source. If you have a central heating system, you may run
system’s circulating blower while using heater. This will help circulate the heat throughout the house.
WARNING: A qualified technician must install heater. Follow all local codes.
WARNING: Never install the heater
in a bedroom or bathroom
in a recreational vehicle
Where curtains, furniture, clothing, or other flammable objects are less than 42 inches from the front, top or sides
of the heater.
in high traffic areas
in windy or drafty areas
CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces next to heater. Installing
heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco smoke, aromatic
candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may cause walls to discolor.
WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling and adjoining
side and back walls.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without
enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation,
pages 7 through 9.
CHECK GAS TYPE
Use only the type of gas indicated on the plate. If your gas supply cannot meet that requirement, do not install heater.
CLEARANCES TO COMBUSTIBLES
Carefully follow the instructions below. This heater is a wall mount unit designed to mount directly on a wall.
IMPORTANT: You must maintain minimum wall and ceiling clearances during installation.
The minimum clearances are shown in Figure 4. Measure from outermost point of heater.
Minimum Wall and Ceiling Clearances (see Figure 4)
A. Clearances from outermost point of heater to any
combustible side wall should not be less than 12
inches.
B. Clearances from the heater to the ceiling should
not be less than 48 inches.
Figure 4 – Minimum Clearance to Wall and Ceiling

11
CONNECTING TO GAS SUPPLY
WARNING: A qualified technician must connect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8 in. NPT inlet connection to pressure regulator (see Figure 5).
CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). The
external regulator between the gas supply and heater must be installed.
INSTALLATION ITEMS NEEDED
Before installing heater, make sure you have the items listed below.
piping (check local codes)
sealant (resistant to propane/LP gas)
equipment shutoff valve*
test gauge connection**
sediment trap
tee joint
pipe wrench
Flexible Gas hose (check local code)
A CSA design-certified equipment shutoff valve with 1/8 in. NPT tap is an acceptable alternative to test gauge
connection. Purchase the optional CSA design certified equipment shutoff valve from your dealer.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You
must reduce incoming gas pressure to between 11 and 14 inches of water column for propane and between 5
and 10.5 inches of water column for natural gas. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the vent pointing down as shown in Figure 6. Pointing the
vent down protects it from freezing rain or sleet.
Figure 6 - External Regulator With
Vent Pointing Down
Figure 5 - Gas Regulator Location and Gas
Line Access Into Stove Cabinet

12
CAUTION: Use only new black iron or steel pipe. Internally tinned copper tubing may be used in certain areas.
Check your local codes. Use pipe of ½ inch diameter or greater to allow proper volume gas to heater. If pipe is
too small, loss of pressure will occur. Installation must include an equipment shutoff valve, union, and plugged
1/8-inch NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater
(see Figure 7).
IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on
or shutting off the gas to the appliance. Apply pipe joint sealant lightly to male threads. This will prevent excess
sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
CAUTION: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We recommend that you install a
sediment trap in a supply line as shown in Figure 7. Locate sediment trap where it is within reach for cleaning and
not likely to freeze. Install in the piping system between fuel supply and heater. A sediment trap traps moisture
and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed
incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or
fittings. NG Models: 5 in. to 10.5 in. W.C.
*Purchase the optional CSA design-certified equipment shut off valve from your dealer. See "Accessories".
** Minimum inlet pressure for purpose of input adjustment.
CAUTION: Two gas line installations at the same time are forbidden. You are not allowed to open the cover while the
machine is running.
Heater is pre-set at factory for propane gas, no changes are required for connecting to propane. Only a qualified installer
or service technician can perform gas selection and connecting to gas supply.
CAUTION: To avoid gas leakage at the inlet of regulator, a qualified installer or service technician must use steel
or metal hex plug with sealant.
For changing from propane to natural gas supply
1. Remove bottom screw from cover plate, see Figure 8, and rotate to expose gas selection valve.
2. For NATURAL GAS, press in knob using a flat screwdriver with a blade the width of a quarter and turn knob
clockwise until the knob locks into the NG position (see Figure 9). Selection valve must be locked into the NG
position. Do not operate heater between locked positions!
3. Rotate and close cover over gas selection valve and reinstall screw.
4. Remove steel or metal hex plug (with wrench provided) from natural gas inlet of regulator and install into LP inlet of
regulator, use thread sealant to assure there are no leaks.
Figure 7 – Gas Connection

3. Turn control knob clockwise to the OFF position, see Figure 14.
4. Wait five (5) minutes to clear out any gas. Then smell for gas around heater and near floor. If you smell gas,
STOP! Follow "B" in the safety information on Warnings plate. If you don't smell gas, go to the next step.
5. Turn control knob counterclockwise to the PILOT position. Keep control knob pressed in for five (5) seconds.
Note: You may be running this heater for the first time after hooking up to gas supply. If so, the control knob may
need to be pressed in for 30 seconds. This will allow air to bleed from the gas system. If control knob does not
pop up when released, contact a qualified service person or gas supplier for repairs.
6. With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to
the rear of the front burner. If needed, keep pressing ignitor button until pilot lights. Note: If pilot does not stay lit,
contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match.
7. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Note: If
pilot goes out, repeat steps 3 through 7. This heater has a safety interlock system. Wait one (1) minute before
lighting pilot again.
8. Warning Make sure while the input gas type is NG, pilot burner NG ignites; while the input type is LP, pilot
burner LP ignites. Note: If you find anything abnormal in this step, repeat steps 2 through 8.
9. Turn control knob counterclockwise to the desired heating level. The main burner should light. Set control knob
to any heat level between HI and LO (5 –1).
THERMOSTATIC CONTROL OPERATION
Note: The thermostatic control valve used on this model differs from standard thermostats. Standard thermostats
simply turn the burner on and off. The thermostat sensing bulb on the control valve used on this heater senses
changes in room temperature and will vary the flame accordingly. When the room temperature exceeds the set
temperature the burner will shut off completely. The unit will cycle back on as the room temperature drops below the
set temperature. The control knob can be set to the desired comfort level between HIGH (5) and LOW (1).

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
1. Turn control knob to pilot position
2. Inspect pilot flame and refer to Figure 15 and 16.
Figure 15 shows a correct pilot flame pattern.
Figure 16 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This
will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
If the pilot flame is incorrect, as shown in Figure 16.
Turn heater off (see To Turn off Gas to Appliance, page 18) See troubleshooting, page 21-23.
BURNER FLAME PATTERN
Figure 17 shows a correct burner flame pattern. Figure 18 shows an incorrect burner flame pattern. If pilot flame
pattern is incorrect then:
Turn heater off (see “To Turn off Gas to Appliance,” page 18).
See Troubleshooting, pages 21 through 23.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the fitting at the entrance to the burner. These holes may become
blocked with dust or lint. Periodically inspect these holes for any blockage and clean as necessary. Blocked air holes
will create soot.

CARE AND MAINTENANCE
WARNING: Failure to keep primary air openings of burners clean may result in sooting and property damage.
CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these
areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more
frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame.
Keep these holes clear of dust, dirt and lint. Clean these air inlet holes prior to each heating season. Blocked air holes
will create soot. We recommend that you clean the unit every 500 hours of operation or every three months.
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with
yellow flame present. All round burner flame holes should be open with a small blue flame Present. Some burner flame
holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool, either remove
blockage or replace burner. Blocked burner flame holes will create soot.
CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 500 hours of operation. We also recommend that you
keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. You can use a vacuum cleaner in the blow position. If using compressed air in a
can, please follow the directions on the can. If you don't follow directions on the can, you could damage the pilot assembly.
1. Shut off the unit, including the pilot. Allow the
unit to cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet holes
on injector holder for dust and dirt (see Figure 19).
3. Blow air through the ports/slots and holes in
the burner.
4. Check the injector holder located at the
end of the burner tube again. Remove any large
particles of dust, dirt, lint, or pet hair with a soft cloth or
vacuum cleaner nozzle.
5. Blow air into the primary air holes on the
injector holder.
6. In case any large clumps of dust have now
been pushed into the burner. Repeat steps
3 and 4. Clean the pilot assembly also.
CLEANING ODS/PILOT
Use a vacuum cleaner, pressurized air, or a small,
soft bristled brush to clean.
A yellow tip on the pilot flame indicates dust and dirt in
the pilot assembly. There is as mall pilot air inlet hole
about two inches from where the pilot flame comes out of the
pilot assembly (see Figure 20). With the unit off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if compressed air is not available
