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 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.
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
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 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 these three
criteria, you must provide additional
fresh air. See
doors
, page 8
If your home does not meet all of the three
criteria above, proceed to

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 m
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
3
m
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) = 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.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example:
35,840 (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.

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)
35,840 Btu/Hr (maximum the space
can support)
40,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above 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. Y ou will need no additional fresh air ventilation.
WARNING: If the area in
which the fireplace 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

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.
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 20).
IMPORTANT:
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 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.
Install equipment shutoff valve in
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This gas is
commonly known as wellhead gas.
IMPORT ANT:
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 .
For natural gas, check gas line pressure
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 19. 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
fireplace. If pipe is too small, undue loss of volume will occur.

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 receiv er
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 fir eplace off. This feature is not a vailable 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 r eceiver
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
Make sure the heater switch is on AUTO and
set the temperature adjustment on wall thermostat to the desired setting. The thermostat
has been electronically calibrated at the factory
and requires no adjustment or leveling.
Upon installation, the thermostat must be allowed to stabilize at room temperature for a
minimum of 30 minutes for proper operation.
See installation instructions on pages 19 and 20.
OPTIONAL GWMS2 WALL
MOUNTED SWITCH
Make sure the heater switch is on A UTO. This wall
switch works just like the conventional light switch.
Flip the switch up for on and down for off.
Note:
Make sure that this switch is not in a position to be mistaken for a light switch. This may
result in the fireplace being inadvertently tur ned
on without the proper precautions being taken.
See installation instructions on pages 19 and 20.
OPERATING
BLOWER
This blower has three settings: ON, OFF, and
AUTO. In the ON position, the blow er will operate constantly. In the OFF position, the
blower will not operate. In the AUTO position,
the blower will start when the thermostat senses
a sufficient increase in firebox temperature.
Note:
Your fireplace and thermostat blower
will not turn on and off at the same time. The

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 46 shows a correct pilot flame pattern. Figure 47 shows an incorrect pilot flame pattern. The
incorrect pilot flame is not touching 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 47
• turn fireplace off (see To Turn Off Gas to Appli-ance, page 22 for Thermostat-Controlled Models
or page 24 for Remote-Ready Models)
• see Troubleshooting, pages 29 through 32
Note:
The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.

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.
CLEANING 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. 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 50).
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 assembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figures 51 or 52 depending 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.
