OPERATION
This vent-free fireplace is clean burning. It requires
no outside venting. There is no heat loss out a vent
or up a chimney. Heat is generated by both realistic
flames and glowing embers. When used without the
blower, the fireplace requires no electricity making
it ideal for emergency backup heat.

THERMOASTAT CONTROL
This fireplace has a thermostat sensing bulb and
control valve. The thermostat controls the heat
output and flame height. This maintains a consis-
tent room temperature. Even the lowest setting
provides realistic flames and glowing embers from
two burners. Selecting higher comfort settings al-
lows fireplace to run longer, producing greater heat
output.At lower comfort settings, the fireplace will
run less. This results in increased heating comfort.
This can also result in lower gas results.

WARNING: This firebox shall
not be installed in a confined
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tionandventilationair. Readthe
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
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.
Today’s 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.
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, page 8.
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 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.
Exhaust fans, fireboxes, 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:
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.
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.
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.

Use this work sheet to determine if you have a
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:
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.
A. Rework worksheet, adding the space of an adjoin-
ingroom. Iftheextraspaceprovidesanunconfined
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation
Air From Inside Building, page 9.

width x height).
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors, page 9.
Length x Width x Height =__________cu. ft.
(volume of space)
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
Example: Space size 22 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 3168 cu. ft.
(volume of space)
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
an unconfined space. You will need no additional
fresh air ventilation.
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.

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" 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 17. Pointing the vent down
protects it from freezing rain or sleet.

Installation Items Needed
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).

•
5/16" hex socket wrench or nut-driver

sealant (resistant to propane/LP gas, not pro-
vided)
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.
1. Remove fireplace screen. Remove one screw
that holds fireplace screen in place for ship-
ping. This screw is located near top left side
of screen. Discard screw. Lift fireplace screen
up and pull out to remove.
Check your building codes for any special re-
quirements for locating equipment shutoff valve
to fireplaces.
2. Remove screws that attach log base assembly
to fireplace (see Figure 19). Carefully lift up
log base assembly and remove from fireplace
(see Figure 19).
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.
Note: If adding the G8000 series brick liner acces-
sory, install it now. Follow instructions in G8000
accessory kit.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
CAUTION: Do not pick up
log base assembly by burner.
Thiscoulddamageburner. Only
handle base by grates.
We 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.
3. Route gas line (provided by installer) from
equipment shutoff valve to fireplace. Route
flexible gas supply line through one of the
access holes.

insPecTinG bUrners
Continued
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.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
orotherfineparticlesareburned
by fireplace, causing brief
patches of orange flame.
If front burner flame pattern is incorrect, as shown
in Figure 32 on page 19
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.

CAUTION: You must keep
control areas, burner and cir-
culating 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.
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.
