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.
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 dehumidifier 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 confined 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 efficient
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
efficient, 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, fireplaces, 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.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 7 through 9 will help
you classify your space and provide adequate
ventilation.

AIR FOR COMBUSTION AND VENTILATION
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 defines a confined space as a space
whose volume is less than 50 cubic feet per
1,000 Btu/hr (4.8 m3 per kw) of the aggregate
input rating of all appliances installed in that
space and an unconfined space as a space
whose volume is not less than 50 cubic feet per
1,000 Btu/hr (4.8 m3 per kw) of the aggregate
input rating of all appliances installed in that
space. Rooms communicating directly with the
space in which the appliances are installed*,
through openings not furnished with doors, are
considered a part of the unconfined space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this work sheet to determine if you have
a confined or unconfined space.
Space: Includes the room in which you will
install heater plus any adjoining rooms with
doorless passageways or ventilation grills
between the rooms.
1. Determine the volume of the space (length
x width x height).
Length x Width x Height =__________
cu. ft. (volume of space)
Example: Space size 20 ft. (6.1 m)
(length) x 16 ft. (4.88 m) (width) x
8 ft. (2.44 m) (ceiling height) = 2560 cu.
ft. (72.49 m3) (volume of space)
If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can
support.
_ ________(volume of space) x 20 =
(Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (72.49 m3) (volume
of space) x 20 = 51,200 (maximum Btu/
Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.

_ _______Btu/Hr (maximum can support)
_ _______Btu/Hr (actual amount used)
Example:51,200 Btu/Hr (maximum the
space can support)
56,000 Btu/Hr (actual amount
of Btu/Hr used)
The space in the above example is a confined
space because the actual Btu/Hr used is more
than the maximum Btu/Hr the space can support. You must provide additional fresh air.
Your options are as follows:
A. Rework worksheet, adding the space
of an adjoining room. If the extra space
provides an unconfined space, remove
door to adjoining room or add ventilation
grills between rooms. See Ventilation Air
From Inside Building, page 9.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 9.
C. Install a lower Btu/Hr heater, if lower Btu/
Hr size makes room unconfined. If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space
is an unconfined space. You will need no
additional fresh air ventilation.

200045-01A
AIR FOR COMBUSTION AND VENTILATION
WARNING: If the area in which the heater may be operated is
smaller than that defined as an unconfined 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 International Fuel Gas Code,
or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining
unconfined space, you must provide two permanent openings: one within 12" of the ceiling
and one within 12" of the floor 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
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 unconfined space. The combined
spaces must have enough fresh air to supply
all appliances in both spaces.
Provide extra fresh air by using ventilation
grills or ducts. You must provide two permanent openings: one within 12" of the ceiling
and one within 12" of the floor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel

Pipe Thread) inlet connection to
the pressure regulator.
WARNING: Do not overtighten gas connections.
200045-01A
CAUTION: Use only new,
black iron or steel pipe. Internally 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: 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. The
installer provides the external
regulator for propane/LP gas.

INSTALLATION
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
into gas piping and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to Propane/
LP 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
• flexible gas hose (check local codes)
* A CSA design-certified equipment shutoff
valve with 1/8” NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design certified equipment
shutoff valve from your dealer.
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 13).
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.
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 water.
If you do not reduce incoming gas pressure,
heater regulator damage could occur. Install
external regulator with the vent pointing down

the vent down protects it from freezing rain
or sleet.
Install sediment trap in supply line as shown
in Figure 13, page 14. 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.
Note: The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
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 flame pattern and burner flame pattern often.
Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance,
page 20) or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot flame pattern.
Figure 25 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermocouple to cool, which shuts the heater off.
If pilot flame pattern is incorrect, as shown
in Figure 25
• turn heater off (see To Turn Off Gas to Appliance, page 18)
• see Troubleshooting pages 21 through 23.
WARNING: If yellow tipping
occurs, your heater could produce increased levels of carbon
monoxide. If the burner flame
pattern shows yellow tipping,
follow instructions below.
Notice: Do not mistake orange flames with
yellow tipping. Dirt or other fine particles enter
the heater and burn causing brief patches of
orange flame.
Figure 24 - Correct Pilot Flame Pattern
Figure 25 - Incorrect Pilot Flame Pattern
BURNER FLAME PATTERN
Figure 26 shows a correct burner flame pattern. Figure 27 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than 1/2 the heat
shield height.
If burner flame pattern is incorrect, as shown
in Figure 27
• turn heater off (see To Turn Off Gas to Appliance, page 18)
• see Troubleshooting pages 21 through 23.

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 qualified service technician. 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 flame. 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 qualified 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.
20
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 flame indicates dust and dirt in the
pilot assembly. There is a small pilot air inlet
about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 28). With
the unit off, lightly blow air through the air
inlet. You may blow through a drinking straw
if compressed air is not available.
