UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied
to heater for shipping
3. 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 (0.3 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.
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
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.
WARNING: 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.
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, fireplaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
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, the International Fuel Gas Code, or
applicable local codes.

is commonly known as wellhead
gas.
WARNING: Do not overtighten 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" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
CAUTION: For natural gas,
check your gas line pressure
before connecting heater to gas
line. Gas line pressure must be
no greater than 9.5" of water. If
gas line pressure is higher, heater
regulator damage could occur.
200345-01A
CAUTION: For propane/
LP gas, 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. Gas
supplier provides external regulator for natural gas. The installer
provides the external regulator
for propane/LP gas.
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/LP or Natural Gas).
Before installing heater, make sure you have
the items listed below:
• piping (check local codes)
• sealant (resistant to natural gas and propane/LP gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• flexible gas hose (check local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design certified equipment
shutoff valve from your dealer.

ing gas pressure. You must reduce incoming
gas pressure to between 11" and 14" 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 16. Pointing the vent down
protects it from freezing rain or sleet.
Install sediment trap in supply line as shown
in Figure 15. 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.

INSPECTING BURNERS
IMPORTANT: Owner’s should check pilot flame pattern and burner flame pattern often.
Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance,
page 22) or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern.
Figure 24 shows an 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, as shown
in Figure 24
• turn heater off (see To Turn Off Gas to Appliance, page 19)
• see Troubleshooting pages 23 through 26.
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.

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.
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
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 the heater and let it cool, and remove
blockage or replace burner. Blocked burner
flame holes will create soot.
BURNER INJECTOR HOLDER AND 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. Remove four screws securing front panel.
3. Pull front panel forward.
4. Inspect burner and pilot for dust and dirt.
5. Blow air through the ports/slots and holes
in the burner.
6. Replace front panel using screws removed.
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 a small
pilot air inlet hole about 2" from where the
pilot flame comes out of the pilot assembly
(see Figure 17). 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.

CARE AND MAINTENANCE
MAINTENANCE OF BLOWER MOTOR
Always disconnect the appliance from the
main power supply and allow it to cool
before any servicing operation.
The motors used on the fan heater and flame
blower are pre-lubricated for extended bearing life and require no further lubrication.
However, periodic cleaning/vacuuming of the
appliance around the air intake and exhaust,
as well as the fan heater is recommended. For
heavy or continuous use, periodic cleaning
must be done more frequently. If the heater
blows alternating cold and warm air, check the
fan for free movement and for debris restricting air flow. If the fan does not move freely, the
unit must be turned off and the fan replaced
immediately in order to prevent further damage to the unit.
TROUBLESHOOTING
WARNING: If you smell gas:
• Shut off gas supply.
• 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 fire department.
WARNING: Only a qualified service technician should service and
repair heater. Make sure that power is turned off before proceeding.
Turn off and let cool before servicing.
CAUTION: Never use a wire, needle, or similar object to clean
ODS/pilot. This can damage ODS/ pilot unit.
IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover, cigarette smoke, cements and glues, new carpet or textiles, etc.,
create fumes. These fumes may mix with combustion air and create odors.
Note: All troubleshooting items are listed in order of operation.
Problem
Possible Cause
Corrective Action
Using natural gas and
pilot will not light.
Inlet pressure exceeds
9.5" WC.
Bypass pressure switch. See
instructions below.
Pressure Switch
When using natural gas (NG), there is a
pressure switch that acts to turn off the gas
flow to the pilot if the inlet pressure exceeds
9.5" WC. This is to prevent the operation of
the unit on the wrong gas (propane/LP). If your
natural gas supply exceeds 9.5" WC the unit
will not operate. Either contact your gas supplier to check and adjust the inlet pressure or
a qualified service technician can bypass the
pressure switch.
200345-01A
Before attempting to bypass the pressure
switch, make sure the type of gas being used
is correct. Check to make sure the connection
fitting is in the correct inlet on the regulator.
Refer to Connecting to Gas Supply, page 15.
Only a qualified installer should bypass the
pressure switch. To bypass the pressure
switch locate the set screw on the regulator.
Use a small flat bladed screw driver to turn the
set screw counterclockwise 2 turns. This will
bypass the pressure switch function.
