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 top inner pack.
2. Tilt carton so that heater is upright.
3. Remove protective side packaging.
4. Slide heater out of carton.
5. Remove protective plastic wrap.
6. Hold the screen, lift, and pull forward.
7. Remove log set by cutting plastic ties.
8. Carefully unwrap logs.
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 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 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 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: Iftheareainwhich
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.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
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 4).
Follow the National Fuel Gas Code, ANSI

INSTALLATION
CONNECTING TO GAS SUPPLY
CAUTION: For natural gas,
check your gas line pressure
before connecting heater to gas
line. Gas line pressure must be
no greater than 9" of w.c. 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 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-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 1/2" 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
10, page 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.
WARNING: A qualied 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: 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 direct-
ly to the gas supply. This heater
requires an external regulator
(not supplied). Install the external
regulator between the heater and
propane/LP gas supply. Gas sup-
plier provides external regulator
for natural gas. The installer
provides the external regulator
for propane/LP 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.

INSTALLATION
Figure 10 - Gas Connection
Figure 9 - Gas Regulator Location and
Gas Line Access Into Stove Cabinet
* Purchase the optional CSA design-certied equipment
shutoff valve from your dealer.
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 installations, the installer must
supply an external regulator. The external
regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to
between 11" and 14" of w.c. If you do not re-
duce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
11. Pointing the vent down protects it from
freezing rain or sleet.
For both gas types, install sediment trap in
supply line as shown in Figure 10. 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 sedi-
ment trap is not installed or is installed wrong,
heater may not run properly.

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 20 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 19 shows a correct pilot ame pattern.
Figure 20 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 20
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 18)
• see Troubleshooting pages 22 through 25.
WARNING: If yellow tipping
occurs, your heater could produce
increased levels of carbon mon-
oxide. If the burner ame pattern
shows yellow tipping, follow in-
structions 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.

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 qualied 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.
MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. All round burner ame holes should be
open with a small blue ame present. Some
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.

We recommend that you clean the unit ev-
ery 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 us-
ing 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 23).
3. Blow air through the ports/slots and holes
in the burner. Also clean the pilot assembly.
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
injector holder.
6. In case any large clumps of dust have now
been pushed into the burner. Repeat steps
3 and 4.
