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 ener gy 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.
AIR FOR COMBUSTION
AND VENTILATION
Continued
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/NFP A 54, Section 5.3, 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 5 through 7 will help you
classify your space and provide adequate ventilation.
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 out-
side atmosphere have a continuous
water vapor retarder with a rating of one
perm (6 x 10
with openings gasketed or sealed
b. weather stripping has been added on
openable windows and doors
c. caulking or sealants are applied to ar-
eas such as joints around window and
door frames, between sole plates and
floors, 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 m ust provide additional fresh air .
See
Ventilation Air From Outdoor s
If your home does not meet all of the three
criteria above, proceed to

and
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 per hour (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
per hour (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 FIREPLACE 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
fireplace 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:
(width) x 8 ft. (ceiling height) = 2,560 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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example:
51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free fireplace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas fireplace logs _________ Btu/Hr
Other gas appliances* + ________ Btu/Hr
Total = ________ Btu/Hr
* Do not include direct-vent gas appliances. Di-
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
Space size 20 ft. (length) x 16 ft.
2,560 cu. ft. (volume of space) x 20 =
AIR FOR COMBUSTION
AND VENTILATION
Continued
Example:
Gas water heater _____________ Btu/Hr
Vent-free fireplace _____________ Btu/Hr
Total _____________ Btu/Hr
4. Compare the maximum Btu/Hr the space can
support with the actual amount of Btu/Hr used.
________
________
Example:
Btu/Hr (maximum the space can support)
Btu/Hr (actual amount of Btu/Hr used)
51,200 Btu/Hr (maximum the space
can support)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the 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 adjoin-
ing 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.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors.
C. Install a lower Btu/Hr fireplace, 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 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,

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified service person must connect fireplace to gas supply. Follow all
local codes.
CAUTION: Never connect propane/LP fireplace directly to the
propane/LP supply. This fireplace
requires an external regulator (not
supplied). Install the external regulator between the fireplace and
propane/LP supply.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This gas
is commonly known as wellhead gas.
Installation Items Needed
Before installing fireplace, 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 propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
• approved flexible gas line with gas connector
(if allowed by local codes) (not provided)
* 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. See Accessories, pages 32 through 34.

INSTALLATION
Continued
For propane/LP units, 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. 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 17. 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 fireplace. If pipe is too small, undue
loss of volume 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 fireplace (see Figure 18).
IMPORTANT:
accessible location. The equipment shutoff valve is
for turning on or shutting off the gas to the appliance.
Check your building codes for any special requirements for locating equipment shutoff valve
to fireplaces.
Apply pipe joint sealant lightly to male NPT threads.
This will prevent excess sealant from going into
pipe. Excess sealant in pipe could result in clogged
fireplace valves. Never use sealant on flare threads.
Install equipment shutoff valve in an
External
Regulator
Propane/LP
Supply Tank
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
W e recommend that you install a sediment trap in
supply line as shown in Figure 18. Locate sediment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
fireplace. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace gas controls. If sediment trap
is not installed or is installed wrong, fireplace may
not run properly.

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot flame pattern. Figure 35 shows an incorrect pilot flame pattern. The
incorrect pilot flame is not properly heating the
thermocouple. When the thermocouple cools, the
heater will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 35
• turn heater off (see To Turn Off Gas to Appli-
ance, page 18)
• see Troubleshooting, pages 23 through 26
Note:
The pilot flame on natural gas units will
have a slight curve, but flame should be blue and

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and circulating air passageways of fireplace clean. Inspect these areas
of fireplace before each use.
Have fireplace inspected yearly
by a qualified service person.
Fireplace 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 INJECTOR 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 flame. 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 qualified service person.
W e 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. Y our 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, pilot, and primary air inlet
holes on injector holder for dust and dirt (see
Figure 38).
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.
