200372-01A6
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.
AIR FOR COMBUSTION AND VENTILATION
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 dehumidier 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.
WARNING: This heater shall
not be installed in a conned
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.
Today’s homes are built more energy efcient
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
efcient, 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, replaces, 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: 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.
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.

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. In the event of a power
outage, you can use this heater
as your primary heat source.
WARNING: A qualied ser-
vice person must install heater.
Follow all local codes.
WARNING: Before installing
in a solid fuel burning replace,
the chimney ue and rebox
must be cleaned of soot, creosote, ashes and loose paint by
a qualified chimney cleaner.
Creosote will ignite if highly
heated. A dirty chimney ue may
create and distribute soot within
the house. Inspect chimney ue
and rebox for damage. If damaged, repair ue before operating heater.
WARNING: Seal any fresh
air vents or ash clean-out doors
located on oor or wall of replace. If not, drafting may cause
pilot outage or sooting. Use a

CONNECTING TO GAS SUPPLY
WARNING: A qualied ser-
vice technician must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance
requires a 3/8" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: Do not overtighten gas connections.
WARNING: For natural gas,
Never connect heater to private
(non-utility) gas wells. This gas
is commonly known as wellhead
gas.
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 propane/LP supply.
Gas supplier provides external
regulator for natural gas. The
installer provides the external
regulator for propane/LP gas.
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" WC. If gas
line pressure is higher, heater
regulator damage could occur.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
into gas piping and/or ttings.
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:
• external regulator for propane/LP unit only
(supplied by installer)
• 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
• exible gas hose (check local codes)
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design certied equipment
shutoff valve from your dealer.

200372-01A14
INSTALLATION
Typical Inlet Pipe Diameters
Use 3/8" black iron pipe or greater. Installation must include an equipment shutoff valve,
union, and plugged 1/8" 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.
For propane/LP installations, 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.
For propane/LP gas, the installer must supply
an external regulator. The external regulator
will reduce incoming gas pressure. You must

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.

REMOTE CONTROL OPERATION
NOTES
The Thermo Feature on the transmitter operates the appliance whenever the ROOM
TEMPERATURE varies a certain number of
degrees from the SET TEMPERATURE.
This variation is called the “swing” or temperature differential. The normal operating
cycle of an appliance may be 4 times per
hour depending on how well the room or
home is insulated from the cold or drafts.
The factory setting for the “swing number” is
2. This represents a temperature variation of
+/-2°F (1°C) between SET temperature and
ROOM temperature, which determines when
the replace will be activated. The transmitter
has ON and OFF manual functions that are
activated by pressing either button on the
face of the transmitter. When a button on the
transmitter is pressed the word ON or OF will
appear on the LCD screen to show while the
signal is being sent. Upon initial use, there
may be a delay of three seconds before the
remote receiver will respond to the transmitter.
This is part of the system’s design.

open with a small blue ame present. Some
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. Inspect burner, pilot and primary air inlet
holes on injector for dust and dirt (see
Figure 32).
3. Blow air through the ports/slots and holes
in the burner. Also clean the pilot assembly.
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off the heater and let it cool, and remove
blockage or replace burner. Blocked burner
ame holes will create soot.
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

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. These odors will disappear over time.
Note: All troubleshooting items are listed in order of operation.
Problem Possible Cause Corrective Action
Using natural gas and
pilot will not light.
Pressure Switch
When using natural gas (NG), there is a pressure switch that acts to turn off the gas ow 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
qualied service technician can bypass the
pressure switch.
Before attempting to bypass the pressure
switch, make sure the type of gas being used
is correct. Check to make sure the connection
tting is in the correct inlet on the regulator.
Refer to Connecting to Gas Supply, page 13.
Only a qualied installer should bypass the
pressure switch. To bypass the pressure
switch locate the set screw on the regulator.
Use a small at bladed screw driver to turn the
set screw counterclockwise 2 turns. This will
bypass the pressure switch function.
Inlet pressure exceeds
9.5" WC.
The entire gas delivery piping including connections inside the heater should be leak
tested by the qualied installer. After leak
testing the qualied installer should light the
appliance. Refer to the correct ame pattern
as illustrated on page 23. All ame patterns
should be safely inside the product. If for any
reason they are not, stop use of the appliance
and call for repairs.
