WATER VAPOR: A BY-PRODUCT OF
UNVENTED ROOM HEATERS
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 recom-
mended 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-
midier 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.
UNPACKING
1. Remove hood from the top foam.
2. Remove the top corner foam.
3. Remove heater from carton.
4. Remove foam from the top screen.
5 Remove protective plastic wrap.
6. Hold the screen, lift, and pull forward.
7. Remove log set by cutting plastic ties.
8. Carefully unwrap log.
9. Check for any shipping damage. If heater
or log is damaged, promptly inform your
dealer where you bought the heater.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a conned 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 efcient
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
efcient, 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 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 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/NFPA54,
the International Fuel Gas Code,
or applicable local codes.

adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 2). You can also remove door
into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the oor. 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 unconned space. The combined
spaces must have enough fresh air to supply
all appliances in both spaces.

CONNECTING TO GAS SUPPLY
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 pro-
pane/LP gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• exible gas hose (check local codes)
• 3/8" NPT brass tting
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design certied equipment
shutoff valve from your dealer.
Typical Inlet Pipe Diameters
Use 3/8" black iron pipe or greater. Installa-
tion 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, page 15).
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.
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.
WARNING: A qualied ser-
vice technician must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance re-
quires a 3/8" NPT (National Pipe
Thread) brass inlet connection
to the pressure regulator.
WARNING: For natural gas,
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: 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.
CAUTION: For propane/
LP gas, never connect heater
directly to the gas supply. This
heater requires an external regu-
lator (not supplied). Install the
external regulator between the
heater and gas supply.

* Purchase the optional CSA design-certied equipment
shutoff valve from your dealer.
The installer must supply an external regula-
tor. The external regulator will reduce incom-
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 13. Pointing the vent down
protects it from freezing rain or sleet.

INSPECTING BURNERS
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 22) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 22, page 21, shows a correct pilot
ame pattern. Figure 23, page 21, 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 23, page 21
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 20)
• see Troubleshooting pages 24 through 27.
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 at bottom of
this page.
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.
OPERATION
Shutting Off Heater
Turn control knob clockwise to the
OFF position.
Shutting Off Burner Only
(pilot stays lit)
Turn control knob clockwise to the
PILOT position.
1. Remove screen by lifting and pulling
forward.
2. Follow steps 1 through 5 under Lighting
Instructions, page 19.
3. With control knob in PILOT position, strike
match, and hold near pilot. Press in control
knob; pilot should light.
4. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob.
5. Make sure the heater screen is in place
before operating heater.
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 ex-
ceed the set temperature. If so, the burner will
shut off. The burner will cycle back on when
room temperature drops below the set tem-
perature. The control knob can be set to any
comfort level between HIGH (5) and LOW (1).
Note: The thermostat sensing bulb measures
the temperature depending on housing con-
struction.
