AIR FOR COMBUSTION
AND VENTILATION
WARNING: This fireplace
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 in
sure 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.

AIR FOR COMBUSTION
AND VENTILATION
Continued
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.
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
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 these three
criteria, 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, proceed to Determining 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
volume is less than 50 cubic feet per 1,000 Btu
per hour (4.8 m
-11
kg per pa-sec-m2) or
3
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.
* 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: Space size 16 ft. (length) x 14 ft.
-
(width) x 8 ft. (ceiling height) = 1792 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.
__________ ( vo l u me o f s p ac e ) x 20 =
(Maximum Btu/Hr the space can support)
Example: 1792 cu. ft. (volume of space) x 20 =
35,840 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.

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.
WARNING: A qualified service
person must connect fireplace to
gas supply. Follow all local codes.
WARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonly
known as wellhead gas.
IMPORTANT: For natural gas, check gas line
pressure before connecting fireplace to gas line.
Gas line pressure must be no greater than 14 inches
of water. If gas line pressure is higher, heater
regulator damage could occur.
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.
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, fireplace regulator damage could occur.
Install external regulator with the vent pointing
down as shown in Figure 22. 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" or greater diameter
to allow proper gas volume to fire
place. 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 heater (see Figure 23).
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.
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.

Safety Features
When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the fireplace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1.
If the average room temperature exceeds 82
degrees Fahrenheit (28 degrees Centigrade),
the hand-held remote control will perform a
safety override and shut the fireplace off. This
feature is not available in the MANU mode.
2. The receiver continuously receives signals
from the hand-held remote to control the
room temperature. If the hand-held remote
is misplaced, obstructed, or for any reason
cannot transmit to the receiver, the receiver
will shut off the fireplace after 8 minutes.
Key Pad Lock Feature
This feature allows the user to lock/unlock
the keypad on the hand-held remote in the
MANU or AUTO mode to prevent inadvertent
operation (i.e. children operating the hand-held
remote control, etc.). The keypad is locked in
either on or off. Press the POWER and LOCK
buttons together to turn the unit on or off.
OPTIONAL GWMT1 WALL
MOUNTED THERMOSTAT

requires no adjustment or leveling.
Upon installation, the thermostat must be al
lowed to stabilize at room temperature for a
minimum of 30 minutes for proper operation.
See installation instructions on page 19.
OPTIONAL GWMS2 WALL
MOUNTED SWITCH
Make sure the heater switch is on AUTO. This wall
switch works just like the conventional light switch.
Flip the switch up for on and down for off.

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,
pet hair, bedding material, 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 fireplace 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 donʼt 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 56, page 29).

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 Figures 57 or 58 depend
ing on model). 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.
