Always handle base assembly by grate.
2. Remove all protective packaging applied to
logs and heater for shipment.
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.
3. Check all items for any shipping damage. If
damaged, promptly inform dealer where you
bought heater.
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.

Confined Space 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 com-
municating directly with the space in which the
appliances are installed*, through openings not
furnished with doors, are considered a part of the
unconfined space.
AIR FOR COMBUSTION
AND VENTILATION
Continued
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.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.

confined or unconfined space.
Unusually Tight Construction
Space: Includes the room in which you will install
fireplace plus any adjoining rooms with doorless pas-
sageways or ventilation grills between the rooms.
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.
1. Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Unusually tight construction is defined as
construction where:
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2,560 cu. ft.
(volume of space)
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6x10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed
and
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.
b. weather stripping has been added on
openable windows and doors and
__________ (volume of space) x 20 = (Maxi-

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.
Example: 2,560 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.

IMPORTANT: If you cannot meet these minimum
clearances, you must operate heater with chimney
flue damper open. Go to Installing Damper Clamp
Accessory for Vented Operation, page 12.
Determining Minimum Mantel Clearance
If you meet minimum clearance between mantel
shelf and top of fireplace opening, a hood is not
required (see Figure 6).
If Using Mantel
You must have noncombustible material(s) above
the fireplace opening. Noncombustible materials
(such as slate, marble, tile, etc.) must be at least
1/2 inch thick. With sheet metal, you must have
noncombustiblematerialbehindit. Noncombustible
material must extend at least 8 inches up (for all
models). If noncombustible material is less than
12", you must install the fireplace hood accessory
(24" model only). Even if noncombustible material
is more than 12", you may need the hood accessory
to deflect heat away from your mantel shelf. See
Figure 5 (see page 9), Figure 6 and Figure 7 (see
page 11) for minimum clearances.
Determining Minimum Mantel Clearance

1. Apply pipe joint sealant lightly to male threads
of the fitting to be threaded into gas regulator.
Connect approved flexible gas hose to gas
regulator of heater (see Figure 11).
IMPORTANT: Hold gas regulator with
wrench when connecting flexible gas hose.
WARNING: A qualified
service person must connect
heater to gas supply. Follow
all local codes.
2. Locate masonry screws in hardware package.
3. Position heater base assembly in fireplace.
4. Place logs in their proper position on heater
base (see Installing Logs, page 16).
5. Center heater base and logs front-to-front and
side-to-side in fireplace.
CAUTION: Never connect
propane/LPheaterdirectlytothe

*ACSAdesign-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, page 31.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install sediment trap in
supply line as shown in Figure 14. Locate sediment
trap where it is within reach for cleaning. Install
in 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 wrong, heater may not run properly.
For propane/LP gas, 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 pres-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 13. Pointing the vent down
protects it from freezing rain or sleet.

BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the fitting at the entrance to the burner. These holes
may become blocked with dust or lint. Periodically
inspect these holes for any blockage and clean as
necessary. Blocked air holes will create soot.

INSPECTING BURNERS
MAIN BURNER
Check pilot flame pattern and burner flame pat-
terns often.
Periodically inspect all burner flame holes with the
heaterrunning. Allslottedburnerflameholesshould
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. Remove blockage,
blocked burner flame holes will create soot.
PILOT FLAME PATTERN
Figure 30 shows a correct pilot flame pattern.
Figure 31 shows an incorrect pilot flame pat-

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.
WARNING: Turn off heater
and let cool before cleaning.
5. Blow air into the primary air holes on the
injector holder.
CAUTION: You must keep
control areas, burner and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heaterinspectedyearlybyaquali-
fied service person. Heater may

to excessive lint from carpeting,
bedding material, pet hair, etc.
6. In case any large clumpsofdusthave nowbeen
pushed into the burner repeat steps 3 and 4.
Clean the pilot assembly also. Ayellow 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 33). 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.

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
and lint. 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.
Ports/Slots

Tube
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 donʼt follow directions on the can,
you could damage the pilot assembly.
