AIR FOR COMBUSTION AND  
VENTILATION  
Unusually tight construction is defined as construction  
where:  
a. walls and ceilings exposed to the outside 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  
WARNING: This heater shall not be installed in a  
confined space or unusually tight construction un-  
less provisions are provided for adequate combus-  
tion and ventilation air. Read the following instruc-  
tions to insure proper fresh air for this and other fuel-  
burning appliances in your home.  
b. weather stripping has been added on openable win-  
dows and doors and  
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.  
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 7.  
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.  
If your home does not meet all of the three criteria above,  
proceed to Determining Fresh-Air Flow for Fireplace Lo-  
cation on page 6.

fuel-burning appliances.  
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  
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper  
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.  
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 following ventilation  
classifications:  
1. Unusually Tight Construction  
2. Unconfined Space  
3. Confined Space  
* Adjoining rooms are communicating only if there are doorless  
passageways or ventilation grills between them.  
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.

DETERMINING FRESH-AIR FLOW FOR  
HEATER LOCATION  
A. Rework worksheet, adding the space of an adjoining 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.  
Determining if You Have a Confined or  
Unconfined Space  
B. Vent room directly to the outdoors. See Ventilation Air From Out-  
doors, page 7.  
Use this work sheet to determine if you have a confined or unconfined space.  
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.  
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining  
rooms with doorless passageways or ventilation grills between the rooms.  
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can  
support, the space is an unconfined space. You will need no additional fresh  
air ventilation.  
1. Determine the volume of the space (length x width x height).  
Length x Width x Height = ___________ cu. ft. (volume of space)  
WARNING: If the area in which the heater may be  
operated is smaller than that defined as an uncon-  
fined space or if the building is of unusually tight  
construction,provideadequatecombustionandven-  
tilation air by one of the methods described in the  
National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec-  
tion 5.3 or applicable local codes.  
Example: Space size 20 ft. (length) x 18 ft. (width) x 8 ft. (ceiling  
height) = 2880 cu. ft. (volume of space)  
If additional ventilation to adjoining room is supplied with grills or open-  
ings, 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 = (Maximum Btu/Hr the space  
can support)  
VENTILATION AIR  
Example: 2880 cu. ft. (volume of space) x 20 = 57,600 (maximum  
Btu/Hr the space can support)  
Ventilation Air From Inside Building  
This fresh air would come from an adjoining unconfined space.  
When ventilating to an adjoining unconfined space, you must  
provide two permanent openings: one within 12" of the ceiling and  
one within 12" of the floor on the wall connecting the two spaces  
(see options 1 and 2, Figure 3). You can also remove door into  
adjoining room (see option 3, Figure 3). Follow the National Fuel  
Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion  
and Ventilation for required size of ventilation grills or ducts.  
3. Add the Btu/Hr of all fuel burning appliances in the space.

ELECTRICAL CONNECTIONS FOR POWER  
CORD  
The push-button switch and decorative wall plate assembly sup-  
plied with your fireplace is pre-mounted at the factory in the lower  
cavity of the fireplace. You may relocate this wall switch assembly  
to a more convenient location such as the side of your mantel or  
directly onto the wall near the fireplace. To mount the wall switch  
assembly, you must first cut openings in the mantel or wall where  
the switch will be located.  
This fireplace operates on 120 VAC, 60 Hz power. An electrical  
power cord is supplied with this unit.  
For Mantel Installation  
1. Determine from which side of the fireplace the power cord will  
exit. Locate the 1.5" diameter hole near the center of floor sup-  
port bracket on appropriate side of lower cavity (see Figure 7).  
Note: If you choose to relocate the wall switch assembly, do so  
before final installation into a mantel or recessing into a wall. If you  
areinstallinganoptionalbloweraccessory,installitatthesametime  
you relocate the wall switch assembly.  
2. Locate power cord. Remove wire tie or tape holding plug end  
of power cord.  
3. Power cord has 2 plastic hole bushings threaded onto it. Route  
cord's 3-prong plug through the 1.5" diameter hole in appro-  
priate floor support bracket.  
CAUTION: The wall switch assembly must never  
be mounted directly above the fireplace where heat  
may damage it. If you relocate wall switch assembly  
fromlowerfireplacecavity, itmustbemountedeither  
on side wall of mantel or on wall to side of fireplace.  
4. Push first plastic bushing completely through hole. Squeeze  
bushing as needed to do this.  
5. Install the second plastic bushing into the hole in the floor sup-  
port bracket by snapping into place.  
For Recessed Installation  
6. Route the 3-prong plug through the 1.5" hole in fireplace  
outer casing.  
If fireplace is to be recessed into a wall (see Built-In Fireplace  
Installation, page 15), we recommend mounting wall switch  
assembly to left side of fireplace. The wall switch assembly should  
be mounted approximately 12" from left edge of fireplace, and less  
than 60" from the floor. IMPORTANT: Do not locate wall switch  
assembly directly in front of wall stud - there must be room behind  
wall board for wires from switch. If you choose to locate wall  
switch assembly to right side of fireplace, the length of the cord  
restricts you to less than 6" from right edge of fireplace and less  
than 48" from floor.  
7. Install the first plastic bushing into this hole by snapping into place.  
8. After you have connected to gas supply and checked your gas  
connections (see pages 15 and 16), plug power cord into any  
convenient 3-prong grounded wall receptacle near fireplace.  
For Recessed Installation  
If an outlet is not installed in fireplace, install model GA3555 -  
Outlet Kit with Cover. This kit will supply a convenient 3-prong  
grounded electrical outlet for power. Refer to installation manual  
provided with this optional accessory for instructions on wiring.  
Note: A qualified installer must make all electrical connections.

If fireplace is to be installed into a mantel, (see Conventional  
Fireplace Installation, page 15) the wall switch assembly may be  
mounted on either side of the mantel, facing to the side. Do not locate  
wall switch assembly anywhere on the front face of the mantel.  
7. Create three openings on wall according to Template 1, page  
33. This is best done by making a pattern to work with on your  
wall. Carefully cut page 33/34 from manual and tape paper  
template vertically onto wall at preferred location. Pierce the  
paper at the centers of the 2 holes with a nail or sharp pencil,  
leaving a mark on the wall. Do the same at centers of the four  
circles near the corners of the rectangle.  
CAUTION:Becarefulofgaslinesandwiringwhen  
moving floor.  
8. Remove paper template from wall.  
9. Drill 3/8" holes at each mark.  
1. Determine the new location for the wall switch assembly. The  
wires attached to switch are six feet long.  
10. Using a straight edge and pencil, connect the outer edges of  
the 4 holes for the rectangle (see Figure 10). This will give you  
cutting lines for the rectangle you will cut in the wall.  
2. Remove 2 screws securing plastic wall switch assembly to  
bracket in fireplace lower cavity. Save screws.  
3. Remove wire tie holding coiled wire attached to wall switch  
assembly (see Figure 8).  
11. Using a keyhole saw, hack saw blade, drill, file, or other suit-  
able tool, carefully cut out the rectangular opening. Note: The  
corners of the rectangle may be round. IMPORTANT: Do not  
exceed the size of the rectangle on template.  
4. Remove wall switch assembly from bracket.  
5. Carefully pass wall switch assembly and cord through large  
elongated hole in rear of either left or right floor support bracket,  
depending on desired location of switch. Pass wall switch as-  
sembly and cord through 1.5" diameter hole in side of fire-  
place outer casing (see Figure 9).  
12. From inside the recessed opening for the fireplace, carefully  
pass wall switch assembly through the rectangular opening to  
the outside of the wall.  
13. Using wall anchors supplied in hardware package, fold wall  
anchor as shown in Figure 11.  
6. Pull wall switch assembly and cord from fireplace making sure  
wall switch assembly will reach desired mounting location  
without straining cord assembly.  
14. Insert wall anchor, wings first, into hole. Tap anchor flush to wall.  
15. For thin walls (1/2" or less), insert red key into wall anchor.  
Push red key to “pop” open anchor wings. See Figure 12.  
IMPORTANT: Do not hammer key! For thick walls (over 1/2"  
thick), do not pop open wings.  
If you are mounting wall switch assembly to a wall, continue  
reading. If you are mounting your wall switch assembly to the side  
of the mantel, see page 11.

Installation Items Needed  
Mounting Wall Switch Assembly to Side of Mantel  
Beforeinstallingfireplace,makesureyouhavetheitemslistedbelow.  
• external regulator (supplied by installer, for propane/LPunits only)  
7. Create three openings in the mantel wall according to Tem-  
plate 2, page 33. This is best done by making a pattern to work  
with on the mantel. Carefully cut page 33/34 from manual and • piping (check local codes)  
tape paper template vertically onto mantel wall at preferred  
location. Pierce the paper at the centers of the 2 holes with a  
nail or sharp pencil, leaving a mark on the wall. Do the same  
at centers of the four circles near the corners of the rectangle.  
• sealant (resistant to propane/LP gas)  
• equipment shutoff valve *  
• test gauge connection *  
• sediment trap  
8. Remove paper template from mantel wall.  
• tee joint  
9. Drill 1/8" pilot holes at each mark for top and bottom screw  
holes. Drill 3/8" holes at each mark for centers of four circles  
near corners of rectangle.  
• pipe wrench  
• approved flexible gas line with gas connector (if allowed by lo-  
cal codes) (not provided)  
10. Using a straight edge and pencil, connect the outer edges of the 4  
holes for the rectangle (see Figure 10, page 10). This will give  
you cutting lines for the rectangle you will cut in the mantel wall.  
* A CSA design-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, pages 30 and 31.  
11. Using a keyhole saw, hack saw blade, drill, file, or other suit-  
able tool, carefully cut out the rectangular opening. Note: The  
corners of the rectangle may be round. IMPORTANT: Do not  
exceed the size of the rectangle on template.  
For propane/LP units, the installer must supply an external regula-  
tor. 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, heater regulator  
damage could occur. Install external regulator with the vent point-  
ing down as shown in Figure 14, page 12. Pointing the vent down  
protects it from freezing rain or sleet.  
12. Carefully pass wall switch assembly through rectangular open-  
ing from inside mantel (see Figure 13).  
13. Position wall switch assembly vertically over opening with  
decal lettering upright. Make sure wires freely pass through  
wall without binding. Align holes in wall plate with 1/8" pilot  
holes in mantel wall.

Installation Items Needed  
• 5/16" hex socket wrench or nut-driver  
• Phillips screwdriver  
We recommend that you install a sediment trap in supply line as  
showninFigure15.Locatesedimenttrapwhereitiswithinreachfor  
cleaning. Installinpipingsystembetweenfuelsupplyandfireplace.  
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.

FOR YOUR SAFETY  
READ BEFORE LIGHTING  
WARNING: If you do not follow these instructions  
exactly, a fire or explosion may result causing prop-  
erty damage, personal injury or loss of life.  
A. Using Supplied Wall Switch Assembly  
1. Set manual ignition bypass switch on the control panel to  
the OFF position (automatic ignition position).  
A. This appliance has a pilot which lights automatically when  
using the supplied wall switch or remote control. If you  
have a power outage, the pilot may be lighted by hand with  
push-button piezo ignitor. When lighting the pilot, the fol-  
lowing warnings must be followed.  
2. Press ON/OFF button. Hold for 6 seconds. Gas valve will  
open and electronic ignition will begin sparking to light  
pilot. LED will light. Note:You may be running this heater  
for the first time after connecting to gas supply or at the  
start of your heating season. If so, the ON/OFF button may  
need to be pressed again. This will allow air to bleed from  
gas system. If several attempts to light pilot fail, contact a  
qualified service person or gas supplier for repairs. Until  
repairs are made, light and operate manually (see Manual  
Lighting Instructions for Electric Power Outage, pages 19  
and 20).  
B. BEFORE LIGHTING smell all around the appliance area  
for gas. Be sure to smell next to the floor because some gas  
is heavier than air and will settle on the floor.  
WHAT TO DO IF YOU SMELL GAS  
• Do not try to light any appliance.  
• Do not touch any electric switch; do not use any phone in  
your building.  
3. When pilot flame is lit, the thermocouple is heated by the  
flame. When thermocouple becomes hot (5 to 15 seconds),  
main burner will automatically light on high flame.  
• Immediately call your gas supplier from a neighbor’s  
phone. Follow the gas supplier’s instructions.  
• If you cannot reach your gas supplier, call the fire de-  
partment.

B. Using Hand-Held Wireless Remote Control  
1. Set manual ignition bypass switch on control panel to OFF  
position (automatic ignition position).  
Because this fireplace has an electronic ignition system, in the  
event there is a loss of power, it will be necessary to manually  
light the pilot with the piezo ignitor. After the pilot is lit, the  
main burner will light automatically.  
2. Wait five (5) minutes to clear out any gas. Smell for gas  
around heater and near floor. If you smell gas, STOP! Fol-  
low “B” in the safety information on warnings plate. If you  
don’t smell gas, go to the next step.  
1. Follow steps 1 through 3 under Normal Lighting Instructions,  
pages 18 and 19.  
3. Point remote control toward the lower front of fireplace  
and push both buttons at the same time. Hold for 6 sec-  
onds. The gas valve will open and electronic ignition will  
begin sparking to light the pilot. Note: You will be able to  
hear a clicking sound during this process. LED on wall  
switch will light.  
2. Set manual ignition bypass switch on control panel to ON  
position (manual ignition position). See Figure 39.  
3. The pilot is attached to the rear of the front burner. You  
will be able to see the pilot and spark electrode without  
removing the screen or logs.  
Note: You may be running this heater for the first time  
after connecting to gas supply or at the start of your heat-  
ing season. If so, the ON button may need to be pressed  
again. This will allow air to bleed from gas system. If sev-  
eral attempts to light pilot fail, contact a qualified service  
person or gas supplier for repairs. Until repairs are made,  
light and operate manually (see Manual Lighting Instruc-  
tions for Electrical Power Outage).

4. Place the magnetic manual override handle, provided with  
this unit, on the end of the gas valve stem (see Figure 39,  
page 19).  
OPERATING  
FAN  
This blower has three settings: ON, OFF, and AUTO. In the ON  
position, the blower will operate constantly. In the OFF posi-  
tion, the blower will not operate. In the AUTO position, the  
blower will start when the thermostat senses a sufficient in-  
crease in firebox temperature.  
5. Turn the override handle fully counterclockwise  
to  
the PILOT position. The handle will not stop but will begin  
to slip when you have fully turned to the PILOT position.  
6. While holding the valve handle in the PILOT position, press  
and release piezo ignitor button (see Figure 39, page 19).  
This will light the pilot. If needed, keep pressing ignitor Note: Your fireplace and thermostat blower will not turn on  
button until pilot lights.  
and off at the same time. The fireplace may run for several  
minutes before the blower turns on. After the heater modulates  
to the pilot position, the blower will continue to run. The blower  
will shut off after the firebox temperature decreases.  
7. When pilot flame is lit, hold manual override handle until  
thermocouple heats (approximately 5 to 15 seconds). If pi-  
lot goes out, repeat process. If several attempts to light the  
pilot fail, contact a qualified service person or gas supplier  
for repairs.  
Note: It is safe to operate fireplace with blower turned off.  
However,theblowerhelpsdistributeheatedairfromthefireplace.  
8. When thermocouple is heated, release override handle. The  
main burner will immediately light on high flame. Adjust  
flame size by turning override handle.

Check pilot flame pattern and burner flame patterns often.  
PILOT FLAME PATTERN  
Note: It is safe to operate fireplace with blower turned off.  
However,theblowerhelpsdistributeheatedairfromthefireplace.  
Follow installation instructions included with the blower  
accessory.  
Figure 41 on page 21 shows a correct pilot flame pattern. Figure 42,  
page 21, shows an incorrect pilot flame pattern. The incorrect pilot  
flame is not touching the thermocouple. This will cause the thermo-  
couple to cool. When the thermocouple cools, the heater will shut  
down.  
If pilot flame pattern is incorrect, as shown in Figure 42, page 21  
• turn heater off (see To Turn Off Gas to Appliance, page 19 or col-  
umn 1)  
• see Troubleshooting, pages 23 through 25  
Note: The pilot flame on natural gas units will have a slight curve,  
but the flame should be blue and have no yellow or orange color.

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 Figure 47). With the unit off, lightly blow  
air through the air inlet hole. The access hole for propane/LP pilot  
is on the front of the burner carriange as shown in Figure 47. The  
access hole for natural pilot is behind the pilot bracket on the top of  
burner carriage (see Figure 47). You may blow through a drinking  
straw if compressed air is not available.
