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 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
instructionstoinsure properfresh
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 is
smaller than that dened as
an unconned space or if the
building is of unusually tight
construction, provide adequate
combustion and ventilation air
by one of the methods described
in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, the In-
ternational Fuel Gas Code, or
applicable local codes.
QUALIFIED INSTALLING AGENCY
Only a qualied agency should install and
replace gas piping, gas utilization equipment
or accessories, and repair and equipment ser-
vicing. The term “qualied agency” means any
individual, rm, corporation, or company that
either in person or through a representative
is engaged in and is responsible for:
a) Installing, testing, or replacing gas piping
or
b) Connecting, installing, testing, repairing,
or servicing equipment; that is experienced
in such work; that is familiar with all precau-
tions required; and that has complied with
all the requirement of the authority having
jurisdiction.

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.

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 14).
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 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
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.
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
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 gas supply.

Figure 12 - Gas Connection
* 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.

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.

MANUAL LIGHTING PROCEDURE
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 21) 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 24, page 21, shows a correct pilot
ame pattern. Figure 25, 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 25, page 21,
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 19)
• see Troubleshooting pages 23 through 26.
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.
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.
