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 (30 mL) of
water for every 1,000 BTUs (.3 kw) 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 ensure 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, a dehumidier 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 conned space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air. Read the following instructions to ensure 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 classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8 through 9 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
The National Fuel Gas Code, ANS Z 223.1 denes a conned space as a space whose volume is less than 50 cu. ft. per 1,000
BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space and an unconned space as a space
whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed
in that space. Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished
with doors, are considered a part of the unconned space. This heater shall not be installed in a conned space or unusually tight
construction unless provisions are provided for adequate combustion and ventilation air.
* Adjoining rooms are connecting only if there are door-less 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 dened 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-
11kg per pa-sec-m2) or less with openings gasket 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 oors,
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 9). 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 Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned space.
Space: Includes the room in which you will install heater plus any adjoining rooms with door-less 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 cu. ft. 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 Example:
Gas heater logs ________ BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ___BTU/hr Vent-free heater +26,000 BTU/hr
Total =________________ BTU/hr Total =56,000 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 conned 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 unconned 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 unconned. If the actual BTU/hr used is less than the
maximum BTU/hr the space can support, the space is an unconned space. You will need no additional fresh air ventilation.
WARNING: If the area in which the heater may be operated is smaller than that dened as an unconned 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, ANS Z223.1, Section 5.3 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.

9
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 oor. 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/ANS Z223.1.
Air for Combustion and Ventilation for required size
of ventilation grills or ducts.
Ventilation Air From Inside Building
This fresh air would come from adjoining unconned space.
When ventilating to an adjoining unconned space, you must
provide two permanent openings: one within 12 inches of the
wall connecting the two spaces (see options 1 and 2,
Fig. 2). You can also remove door into adjoining room (see
option 3, Fig. 2). Follow the National Fuel Gas Code NFPA 54/
ANS 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 unconned space. The combined spaces
must have enough fresh air to supply all appliances in
both spaces.

CONNECTING TO GAS SUPPLY
WARNING: A qualied 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 Fig. 10).
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. Gas supplier provides external regulator for natural gas.
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
• exible gas hose (check local code)
A CSA design-certied equipment shutoff valve with 1/8 in. NPT tap is an acceptable alternative to test gauge connection.
Purchase the optional CSA design certied 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 for liquid propane. The external regulator is provided by the gas supplier for
natural gas. 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
Fig. 11. Pointing the vent down protects it from freezing rain or sleet.

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 Fig. 12).
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 Fig. 12. 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 ttings. NG
Models: 5 in. to 10.5 in. W.C.

INSTALLING LOGS
WARNING: Failure to position the parts
in accordance with these diagrams or failure
to use only parts specically approved with this heater may
result in property damage or personal injury.
CAUTION: After installation, and
periodically thereafter, check to ensure that no ame comes
in contact with any log. With the heater set to high, check to
see if ames
contact any log. If so, reposition logs
according to the log installation instructions
in this manual. Flames contacting logs will
create soot.

OPERATION
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a re or explosion may result causing property damage, personal
injury, or loss of life.
NOTICE: During initial operation of new heater, burning logs will give off a paper burning smell. Orange ame will also be
present. Open a window to vent smell. This will last only a few hours.
CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.
A. This appliance has a pilot which must be lit by the electronic ignitor. When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the oor because some gas is
heavier than air and will settle on the oor.
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.
• 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 re department.
C. Use only your hand to push control. Never use tools. If the appliance does not operate, don’t try to repair it. Call a qualied
service technician or gas supplier. Forced or attempted repair may result in a re or explosion.
D. Do not use this appliance if any part has been under water. Immediately call a qualied service technician to inspect the
appliance and to replace any part of the control system and any gas control, which has been under water.
Note: Please wait one minute after shutting off replace to allow the control valve to reset before starting again.
LIGHTING INSTRUCTIONS
Unscrew ignitor cap and install a AAA battery with the + pointing out. Replace cap.
1. STOP! Read the safety information on page 18.
2. Warning: You must operate this heater with the screen in place. Make sure screen is installed before running heater.
3. Turn control knob clockwise to the OFF position, see Fig. 19, page 19.
4. Wait ve (5) minutes to clear out any gas. Then smell for gas around heater and near oor. 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 ve (5) seconds. Note: You may
be running this heater for the rst 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
qualied 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 qualied
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 that while the input gas type is NG, pilot burner NG ignites; while the input type is LP, pilot burner LP
ignites. Note: If you nd 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
The thermostatic control used on this model differs from standard thermostats. Standard thermostats simply turn the burner on
and off. The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature.
If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The
control knob can be set to any comfort level between HIGH (5) and LOW (1).
Note: The thermostat sensing bulb measures the temperature depending on housing construction.
TO TURN OFF GAS TO APPLIANCE
Shut off heater.
Turn Control Knob clockwise to the OFF position. Do not force.
MANUAL LIGHTING PROCEDURE

INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
1. Turn control knob to pilot position
2. Inspect pilot ame and refer to Fig. 20 and 21.
• Fig. 20 shows a correct pilot ame pattern.
• Fig. 21 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching the thermocouple. This will cause the
thermocouple to cool. When the thermocouple cools, the heater will shut down.
• If the pilot ame is incorrect, as shown in Fig. 21, turn heater off (see “To Turn Off Gas to Appliance,” page 19). See
Troubleshooting, page 22 - 23.
