State of Massachusetts: The installation
must be made by a licensed plumber or
gas tter in the Commonwealth of Mas-
sachusetts.
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

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 is a by-product of gas combus-
tion. An unvented room heater produces ap-
proximately 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 dehu-
midier 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 con-
struction unless provisions are
provided for adequate combus-
tion 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 ap-
pliances 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 appli-
ances.
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 de-
scribed 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, combus-
tion 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
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: 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. Inter-
nally 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: Check your gas
line pressure before connect-
ing heater to gas line. Gas line
pressure must be no greater than
10.5" of water. If gas line pres-
sure 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 natu-
ral 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 pro-
pane/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 al-
ternative to test gauge connection. Purchase
the optional CSA design certied equipment
shutoff valve from your dealer.

Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Lo-
cate NPT tap within reach for test gauge hook
up. NPT tap must be upstream from heater
(see Figure 13.
IMPORTANT: Install an equipment shutoff
valve in an accessible location. The equip-
ment 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 13. 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 contami-
nants. This keeps them from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.

Thermocouple
The thermostatic control used on these mod-
els 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.
Note: The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.) Frequent use of your heater
will let you determine your own comfort levels.
4. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob. Follow step 8 under
Lighting Instructions, page 17.

Figure 20 shows a correct pilot ame pattern.
Figure 21 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot ame pattern is incorrect, as shown
in Figure 21
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 18)
• see Troubleshooting pages 21 through 23.
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 20 - Correct Pilot Flame Pattern
Figure 21 - Incorrect Pilot Flame Pattern
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 20) 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
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.

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.
The primary air inlet hole allows the proper
amount of air to mix with the gas. This pro-
vides 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.
CABINET
Air Passageways
Use pressurized air to clean.
Exterior
Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
Figure 24 - Pilot Inlet Air Hole

ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
BURNER PILOT AIR INLET
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 24). With
the unit off, lightly blow air through the air
inlet. You may blow through a drinking straw
if compressed air is not available.
