Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.
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 KWs) of gas input per hour. Unvented room heaters are recommended
as supplemental heat (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 sized properly for the application, including ample combustion air and circulation air.
2. If high humidity is experienced, a 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.
5
AIR FOR COMBUSTION AND VENTILATION
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.
Providing Adequate 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 6 through 8 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space
A confined space is 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 unconfined space as a space whose volume is not less than
50 cubic feet 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 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 (6×10-11kg per pa-sec-m2) or less with openings gasketed or sealed and
b) Weather stripping has been added on openable windows 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”. If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For
Heater Location”.
6
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)
3. Add the BTU/hr of all fuel burning appliances in the space.

Example:
Gas water heater 30,000 BTU/hr
Vent-free heater + 26,000 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 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 ”
on next page.
b) Vent room directly to the outdoors. See “ Ventilation Air From Outdoors ” on next page.
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 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.
Ventilation Air From lnside Building
This fresh air would come from an adjoining unconfined
space. When ventilating to an adjoining unconfined
space, you must provide two permanent openings: one
within 12 inches of the ceiling and one within 12 inches
of the floor on the wall connecting the two spaces
(see options 1 and 2, Figure 1). You can also remove
the door into adjoining room (see option 3, Figure 1).
Follow the National Fuel Gas Code. ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation for
required size of entilation grills or ducts.
Figure 1 - Ventilation Air from Inside Building
NOTE: Base not included. Not for use in
bedrooms or bathrooms.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or
ducts. 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, ANSI Z223.1/ NFPA 54, 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.

CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure
regulator.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
WARNING: Do not over-tighten gas connections.
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 1/2-in. diameter or greater to allow proper gas volume to heater. If pipe is
too small, undue loss of pressure will occur.
NATURAL GAS MODELS:
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no
greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.
PROPANE MODELS:
CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not
supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or
fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
Typical Inlet Pipe Diameters Use 3/8-inch black iron pipe or greater. 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 11).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is
for turning on or shutting off the gas to the appliance.
Figure 11 - Gas Connection (inches)
* Purchase the optional CSA design-certified equipment shutoff valve from your dealer.
12
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.
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. 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 12. Pointing the vent down protects it from freezing rain or sleet.
Install sediment trap in supply line as shown in Figure 11. Place sediment trap
where it is within reach for cleaning. Place sediment trap where trapped matter is
not likely to freeze. A sediment trap traps moisture and contaminants. This keeps
them from going into heater controls. If sediment trap is not installed or is installed
wrong, heater may not run properly.

THERMOSTAT 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 1 and 5.

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot flame pattern. Figure 22 shows a incorrect pilot flame pattern. The incorrect pilot
flame is not touching the thermocouple. This will cause the thermocouple to cool, which shuts the heater off. If
pilot flame pattern is incorrect:
• turn heater off (see “To Turn Off Gas to Appliance” on page 16)
• see Troubleshooting pages 20 through 22.
Figure 22 - Incorrect Pilot Flame Pattern
Figure 21 - Correct Pilot Flame Pattern
WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If
burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn
causing brief patches of orange flame.
BURNER FLAME PATTERN
Figure 23 shows a correct burner flame pattern. Figure 24 shows an incorrect burner flame pattern. If burner
flame pattern is incorrect then:
• turn heater off (see “To Turn Off Gas to Appliance” on page 16).
• see Troubleshooting, pages 20 through 22.

CARE AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing
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 technician. Heater
may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
ODS/PILOT AND BURNER
• Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months. 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 PSl. Your local computer store, hardware store, or home center may carry
compressed air in a can. 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 and pilot for dust and dirt.
3. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. A yellow tip on the pilot
flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from
where the pilot flame comes out of the pilot assembly (see Figure 25). 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.
CABINET
Air Passageways
• Use a vacuum cleaner or pressurized air to clean.
Exterior
• Use a soft cloth dampened with a mild soap and water mixture.
• Wipe the cabinet to remove dust.
