PREPARING FOR INSTALLATION
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 (.3 kw) of gas input
per hour. An unvented room heater is recommended as a supplemental heater (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 en-
hances 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 the proper size for the application, including adequate combustion air and
circulation air.
2. If there is high humidity, a dehumidier 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
This heater shall not be installed in a room or space unless the required volume of indoor combustion
air is provided by the method described in the Nation Fuel Gas Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8-10 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw)
of the aggregate input rating of all appliances installed in that space and an unconning space as a
space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate
input rating of all appliances installed in that space. Rooms connecting directly with the space in
which the appliances are installed*, through openings not furnished with doors, are considered a
part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
* Adjoining rooms are connecting only if there are doorless passageways or ventilation
grills between them.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and venti-
lation. However, in buildings of unusually tight construction, you must provide additional
fresh air.
Unusually tight construction is dened as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed
and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames,
between sole plates and oors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air.
See “Ventilation Air From Outdoors” (page 9). If your home does not meet all of the
three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned 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 × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 cu. ft. (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. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space
can support)
3. Add the BTU/hr of all fuel burning appliances in the space.
Vent-free heater _________ BTU/hr
Gas water heater* ________BTU/hr
Gas furnace _____________BTU/hr
Vented gas heater ________BTU/hr Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 BTU/hr
*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.
_______ BTU/hr (maximum the space can support)
_______ BTU/hr (actual amount of BTU/hr 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 conned 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
unconned 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 unconned. If the actual BTU/hr
used is less than the maximum BTU/hr the space can support, the space is an unconned space.
You will need no additional fresh air ventilation.

PREPARING FOR INSTALLATION
WARNING: If the area in which the heater may be operated does not meet the required
volume for indoor combustion air, combustion 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.

CONNECTING TO GAS SUPPLY
WARNING: A qualied service technician must connect heater to gas supply. Follow all local
codes.
CAUTION: Never connect heater directly to the gas supply. This heater requires an external
regulator (not supplied). The external regulator between the gas supply and heater must be installed.
Gas supplier provides external regulator for natural gas.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known
as wellhead gas.
The installer must supply an external regulator for liquid propane. The external regulator is
provided by the gas supplier for natural gas. The external regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure to between 11 and 14 in. of water column for propane
and between 6 and 14 in. of water column for natural gas. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install external regulator with the vent pointing down as
shown in Fig. 15. Pointing the vent down protects it from freezing rain or sleet.
* Purchase the optional equipment shutoff valve from your local Home Center store.
INSTALLATION
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 ½ in. diameter
or greater to allow proper volume gas to heater. If pipe is too small, loss of pressure
will occur. Installation must include an equipment shutoff valve, union, and plugged
1/8-in. NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must
be upstream from heater (See Fig. 15).
IMPORTANT: Install 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.

1) A variety of options are possible for routing the Gas Connection Lines depending on where
your Gas Supply line is located.
NOTICE: Most building codes do not permit concealed gas connections. Check your local build-
ing code prior to using a Flexible Gas Line for this installation.
2) Identify the gas inlet on the Heater that corresponds to the fuel type for your installation. Re-
move the threaded plug by turning counterclockwise.
Install a 90 degree tting - not included). Be sure to use a gas resistant sealant on the 3/8 NPT
tting. Position the tting so the inlet line can be attached without binding.
3) Install the Gas Line to the 90 Deg. tting and attach to the Shut Off Valve.
4) Check all connections for gas leaks.
CAUTION: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We
recommend that you install a sediment trap in a supply line. Locate sediment trap
where it is within reach for cleaning and not likely to freeze. Install in the piping
system between fuel supply and heater. A sediment trap traps moisture and contaminants.
This keeps them from going into heater controls. If sediment trap is not installed or is
installed incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when
connecting into gas piping and/or ttings. NG Models: 6 in. to 14 in. W.C. Gas

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 person. 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.
BURNER ORIFICE HOLDER AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean
burning ame. Keep these holes clear of dust, dirt, lint and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes 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 PSI. Your local
computer store, hardware store or home center may carry compressed air in a can. 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.
BURNER FLAME PATTERN
Figure 29 shows a correct burner ame pattern. Figure 30 shows an incorrect burner ame pattern.
The incorrect burner ame pattern shows sporadic, irregular ame tipping. The ame should not be
dark or have an orange/reddish tinge.
Note: When using the heater the rst time, the ame will be orange for approximately one hour until
the log cures.
If burner ame pattern is incorrect, as shown in Figure 30
• turn heater off (see To Turn Off Gas to Appliance, page 23).
• see Troubleshooting, page 27.
