UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied
to heater for shipping
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.
State of Massachusetts: The installation
must be made by a licensed plumber or
gas tter in the Commonwealth of Massachusetts.
Sellers of unvented propane or natural
gas-red supplemental room heaters shall
provide to each purchaser a copy of 527
CMR 30 upon sale of the unit.
In the State of Massachusetts the gas
cock must be a T-handle type. The State
of Massachusetts requires that a exible
appliance connector cannot exceed three
feet in length.
3. Check heater for any shipping damage. If
heater is damaged, promptly inform dealer
where you bought heater.
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.

AIR FOR COMBUSTION AND VENTILATION
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 vol-
ume 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.

INSTALLATION
CAUTION: Use pipe joint
sealant that is resistant to 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.
Pressure
Regulator
Typical Inlet Pipe Diameters
Models up to 20,000 BTU/hr use 3/8" black
iron pipe or greater. Models 25,000 BTU/hr
and higher use 1/2" 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 12).
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.
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.
Install sediment trap in supply line as shown
in Figure 12. 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 these models differ 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 HI and LO.

This may not always agree with room temperature (depending on housing construction,
installation location, room size, open air temperatures, etc.) Frequent use of your heater
will let you determine your own comfort levels.

INSPECTING HEATER
IMPORTANT: Owner’s should check pilot ame pattern and burner ame pattern often.
Incorrect ame patterns indicate the need for cleaning (see Care and Maintenance,
page 19) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot ame pattern.
Figure 22 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching
the thermocouple. This will cause the thermocouple to cool, which shuts the heater off.
If pilot ame pattern is incorrect, as shown
in Figure 22
• turn heater off (see To Turn Off Gas to Ap-pliance, page 17)
• see Troubleshooting pages 20 through 22.
Notice: Do not mistake orange ames with
yellow tipping. Dirt or other ne particles enter
the heater and burn causing brief patches of
orange ame.
Figure 21 - Correct Pilot Flame Pattern
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner ame
pattern shows yellow tipping,
follow instructions below.
Figure 22 - Incorrect Pilot Flame Pattern
BURNER FLAME PATTERN
Figure 23 shows a correct burner ame pattern. Figure 24 shows an incorrect burner
ame pattern. The incorrect burner ame
pattern shows yellow tipping of the ame. It
also shows the ame higher than 1/2 the heat
shield height.
If burner ame pattern is incorrect, as shown
in Figure 24
• turn heater off (see To Turn Off Gas to Ap-pliance, page 17)
• 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 qualied service techni-
cian. 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.
ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
BURNER PILOT AIR INLET
The primary air inlet hole allows the proper
amount of air to mix with the gas. This provides a clean burning ame. Keep this hole
clear of dust, dirt and lint. Clean this air inlet
hole prior to each heating season. A blocked
air hole will create soot. We recommend that
you clean the unit every three months during
operation and have heater inspected yearly
by a qualied service person.
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.
Air Passageways
Use pressurized air to clean.
Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
3. Blow air across the ports/slots and holes
in the burner.
4. Never insert objects into the pilot tube.
Clean the pilot assembly also. A yellow tip on
the pilot ame indicates dust and dirt in the
pilot assembly. There is a small pilot air inlet
about 2" from where the pilot ame comes out
of the pilot assembly (see Figure 25). With
the unit off, lightly blow air through the air
inlet. You may blow through a drinking straw
if compressed air is not available.
