AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
not be installed in a confined
space or unusually tight con
struction unless provisions are
provided for adequate combus
tion and ventilation air. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Todayʼs 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 effi
cient, 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, Section 5.3, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three fol
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 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.

AIR FOR COMBUSTION
AND VENTILATION
Continued
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 10-11 kg per pa-sec-m2)
or less with openings gasketed or
sealed and
b. weather stripping has been added on
openable windows 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
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 8.
If your home does not meet all of the three
criteria above, proce ed to Determini ng Fresh-Air Flow For Fireplace Location.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA
54 defines a confined space as a space whose vol-
ume 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 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 door
less 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. (length) x 16 ft.
(width) x 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. 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: 2560 cu. ft. (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.
Vent-free heater ___________
Gas water heater* ___________
Gas furnace ___________
Vented gas heater ___________
Gas fireplace logs ___________
Other gas appliances* + ___________
Total = ___________
* Do not include direct-vent gas appliances. Di
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
Example:

The space in the above example is a confined space
because the actual Btu/Hr used is more than the maxi
mum 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, page 8.
B. Vent room directly to the outdoors. See Ventila

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 45° male flare fitting
5/8"-18 UNF (Unified National
Fine Thread) inlet connection and
the flexible gas line provided.
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.
For propane/LP units, 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, fireplace regulator damage could occur.
Install external regulator with the vent pointing
down as shown in Figure 23. Pointing the vent
down protects it from freezing rain or sleet.
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" or greater diameter 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 24).
IMPORTANT: Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on and shutting off the gas to
the appliance.
Check your building codes for any special re
quirements 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.
WARNING: Use pipe joint
sealant that is resistant to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 24. 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 fire
place controls. If sediment trap is not installed or is
installed wrong, fireplace may not run properly.

THERMOSTAT
CONTROL OPERATION
The thermostatic control used on this fireplace
differs from standard thermostats. Standard
thermostats simply turn on and off the burner.
The thermostat used on this fireplace senses the
room temperature. The thermostat adjusts the
amount of gas flow to the burner. This increases
or decreases the burner flame height. At times
the heater will cycle back on when room tem
perature drops below the set temperature.
The control knob can be set to any heat level
between HI and LO.
Note: The thermostat sensing bulb measures
the temp er at ure of air nea r the firep la ce
cabinet. This may not always agree wit h
room tempera ture (depending on hous ing
construction, installation location, room size,
open air temperatures, etc.). Frequent use of
your fireplace will let you determine your own
comfort levels.
MANUAL LIGHTING
PROCEDURE
1. Follow steps 1 through 5 under Lighting
Instructions, page 20.
2. With control knob pressed in, strike match.
Hold match to pilot until pilot lights.
3. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob. Now follow step 8 under
Lighting Instructions, page 20.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 32 shows a correct pilot flame pattern.
Figure 33 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not properly heating the
thermocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the fireplace
will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 33
• turn fireplace off (see To Turn Off Gas to Ap
pliance, page 20)

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.
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. You can use a
vacuum cleaner in the blow position. If using com
pressed 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
36).
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.
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 as
sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 37). 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.

fireplace will be the responsibility of the owner.
