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 (30ml) of water for every 1,000 BTU’s (.3KW’s) of gas input per hour.
Unvented room heaters are recommended as a supplemental heater (for a room), rather than a primary
heat source (for 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 insure that water vapor does not become a problem.
1. Be sure the heater is sized properly for the application, including adequate 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: 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.
PRODUCING ADEQUATE 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.
Confined and Unconfined Space
Aconfined space is a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8 cubic
meter per kilowatt) of the aggregate input rating of all appliances installed in that space and an
unconfining space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8
cubic meter per kilowatt) 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.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.
* Adjoining rooms are communicating 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 ventilation.
However, in buildings of unusually tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a
rating of one perm (6×10-11kg 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 doors and
c) caulking or sealants are applied to areas such as joints around window and door frames, between sole
plates and floors, between wall-ceiling joints, between wall panels, at penetrations f or 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 (below).
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet 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 × Width × Height=_____________ cu. ft. (volume of space)
Example: Space size 20ft. (length) × 16ft. (width) × 8ft. (ceiling height) = 2560cu. 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.
7

2. Divide the space volume by 50 cubic feet 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)
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 Example:
Vented gas heater BTU/hr Gas water heater 30,000 BTU/hr
Gas heater logs BTU/hr Vent-free heater + 26,000 BTU/hr
Other gas appliances* + BTU/hr Total = 56,000 BTU/hr
Total = 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 that 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 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 8.
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.
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.
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. NFPA 54/ANSI Z223.1,
Air for Combustion and Ventilation for required
size of ventilation grills or ducts.
Figure 2 - Ventilation Air Inside Building
8

Ventilation Air from Outdoors
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 Gas
Code, NFPA 54/ ANSI Z223.1. 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 unconfined space. The combined spaces must have enough fresh air to
supply all appliances in both spaces.
INSTALLATION
NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary
heating system. Do not install this heater as your primary heat source. If you have a central heating system,
you may run system's circulating blower while using the heater. This will help circulate the heat throughout
the house.
WARNING: A qualified technician person must install the heater. Follow all local codes.
WARNING: Never install the heater.
in a bedroom or bathroom
in a recreational vehicle
where curtains, furniture, clothing, or other flammable objects are less than 42 inches
from the front, top, or sides of the heater
in high traffic areas
in windy or drafty areas
CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces next to heater.
Installing heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco
smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may cause walls to
discolor.
WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling, and
adjoining side and back walls.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms
without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and
Ventilation, pages 7 through 9.
CHECK GAS TYPE
Use only the type of gas indicated on the plate. If your gas supply cannot meet that requirement, do not install
heater.
CLEARANCES TO COMBUSTIBLES
Carefully follow the instructions below. This fireplace is a freestanding unit designed to set directly on the floor
or on a mantel base.
IMPORTANT: You must maintain minimum wall and ceiling clearances during installation. The minimum
clearances are shown in Figure 4, page 10. Measure from outermost point of fireplace.
Figure 3 – Ventilation Air from Outdoors
9

Minimum Wall and Ceiling Clearances
(See Figure 4)
A. Clearances from outermost point of fireplace to
any combustible side wall should not be less
than 12 inches.
B. Clearances from the fireplace to the ceiling
should not be less than 48 inches.
CONNECTING TO GAS SUPPLY
WARNING: A qualified 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.
INSTALLATION ITEMS NEEDED
Before installing heater, make sure you have the items listed below.
piping (check local codes)
sealant (resistant to propane/LP gas)
equipment shutoff valve*
test gauge connection**
sediment trap
tee joint
pipe wrench
Flexible Gas hose (check local code)
* A CSA design-certified equipment shutoff valve with 1/8
" NPT tap is an acceptable alternative to test gauge
connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead
gas.
Figure 5 -Gas Regulator Location and Gas Line Access into Fireplace Cabinet
Figure 4 – Minimum Clearance to Wall and Ceiling
10

INSTALLATION CONTINUED
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 inches of water
column for propane and between 5 and 10.5 inches of water
column for natural gas. If you do not reduce incoming
pressure, heater regulator damage could occur.
lnstall external regulator with the vent pointing down as shown
in Figure 6. Pointing the vent down protects
it from freezing rain or sleet.
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, a loss of
pressure will occur. 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 7).
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.
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 as shown in Figure 7. Locate sediment trap where it is within reach for
cleaning. Install in the piping system between fuel supply and heater. Locate 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 incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping
and/or fittings.

to inspect the appliance and to replace any part of the control system and any gas control which has been
under water.
Note: Please wait one minute after shutting off fireplace to allow the electronic module to reset before starting
again.
THERMOSTATIC CONTROL OPERATION
Note: The thermostatic control valve used on this model differs from standard thermostats. Standard
thermostats simply turn the burner on and off. The thermostat sensing bulb on the control valve used on this
heater senses changes in room temperature and will vary the flame accordingly. When the room temperature
exceeds the set temperature the burner will shut off completely. The unit will cycle back on as the room

incorrect pilot flame is not touching the
thermocouple. This will cause the thermocouple
to cool. When the thermocouple cools, the heater
will shut down.
If the pilot flame is incorrect, as shown in Figure16.
Turn heater off (see To Turn off Gas to Appliance,
page 16) See troubleshooting, page 19~21.
BURNER FLAME PATTERN

CARE AND MAINTENANCE
WARNING: Disconnect power before attempting any maintenance or cleaning to reduce the risk of fire,
electric shook or personal injury. Turn off heater and let cool before cleaning.
WARNING: Failure to keep primary air openings of burners clean may result in sooting and property
damage.
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 person. Heater
may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
CLEANING ODS/IGNITOR AND BURNER
Clean with a vacuum cleaner.
CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 500 hours of operation. 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. 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, pilot and primary air inlet holes on
injector holder for dust and dirt (see figure 19).
3. Blow air through the ports/slots and holes in the burner.
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
(see Figure19).
6. In case any large clumps of dust have now been pushed
into the burner, repeat steps 3 and 4.
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 hole about two inches from where the pilot
flame comes out of the pilot assembly (see figure 20). With
the unit off, lightly blow air through the air inlet hole. You
may blow through a drinking straw if compressed air is not
available.
CABINET
Air Passageways
Use a vacuum cleaner or pressurized air to clean.
Exterior
Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
LOGS
If you remove logs for cleaning, refer to Installing Logs (page 14) to properly replace logs.
Replace logs if broken or chipped (dime-sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be
open with yellow flame present. All round burner flame holes should be open with a small blue flame present.
Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater
and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot.
