AIR FOR  
COMBUSTION  
AND  
WARNING  
WARNING ICON  
G
001  
This heater shall not be installed in a confined space 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.  
VENTILATION  
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.  
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 is excerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,  
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 6 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.  
Unusually tight construction is defined as construction where:  
a. walls and ceilings exposed to the outside atmosphere have a continu-  
ous water vapor retarder with a rating of one perm (10-6 per-pa-m2) 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 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 addi-  
tional fresh air. See Ventilation Air From Outdoors, page 9.  
If your home does not meet all of the three criteria above, proceed to page 7.  
Confined and Unconfined Space  
The National Fuel Gas Code (ANSIZ223.1, 1992 Section 5.3) 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 unconfining 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 communicating directly with the space in which the  
appliances are installed*, through openings not furnished with doors, are consid-  
ered 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  
AIR FOR  
COMBUSTION  
AND  
Determining if You Have a Confined or Unconfined Space  
Use this worksheet 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.  
VENTILATION  
1. Determine the volume of the space (length x width x height).  
Continued  
Length x Width x Height =  
___________________  
cu. ft. (volume of space)  
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =  
2560 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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space  
can support.  
____________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr  
the space can support)  
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =

used.  
_________________ Btu/Hr (maximum the space can support)  
_________________ Btu/Hr (actual amount of Btu/Hr used)  
Example: 51,200 Btu/Hr (maximum the space can support)  
56,000 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 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, page 8.  
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 9.  
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. You will need no additional fresh air ventilation.

CONNECTING  
TO GAS  
NOTICE  
A qualified service person must connect fireplace to gas supply.  
Follow all local codes.

WARNING  
WARNING ICON  
G
001  
Never connect fireplace to private (non-utility) gas wells. This gas is  
commonly known as wellhead gas.  
IMPORTANT: 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, fireplace regulator damage could occur.  
CAUTION  
WARNING ICON  
G
001  
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 pressure will occur.  
Installation must include a manual 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 16).  
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant  
from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.  
CAUTION  
WARNING ICON  
G
001  
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.  
Install sediment trap in supply line as shown in Figure 16. Locate sediment trap  
where it is within reach for cleaning. 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 controls. If sediment trap is not installed or is  
installed wrong, fireplace may not run properly.

may result causing property damage, personal injury or loss of life.  
A. This appliance has a pilot which must be lighted by hand. When lighting  
the pilot, follow these instructions exactly.  
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.  
• 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 department.  
C. Use only your hand to push in or turn the gas control knob. Never use  
tools. If the knob will not push in or turn by hand, don’t try to repair it,  
call a qualified service technician or gas supplier. Force or attempted  
repair may result in a fire or explosion.  
D. Do not use this appliance if any part has been under water. Immediately call  
a qualified service technician to inspect the appliance and to replace any  
part of the control system and any gas control which has been under water.  
LIGHTING INSTRUCTIONS  
WARNING

THERMOSTAT CONTROL OPERATION  
The thermostatic control used on this fireplace differs from standard thermo-  
stats. Standard thermostats simply turn on and off the burner. The thermostat  
used on this fireplace senses the room temperature. The thermostat adjusts the  
amount of gas flow to the burner. This increases or decreases the burner flame  
height. At times the room may exceed the set temperature. If so, the burner  
will shut off. The burner will cycle back on when room temperature drops  
below the set temperature.  
The control knob can be set to any heat level between HI and LO.  
Note: The thermostat sensing bulb measures the temperature of air near the  
fireplace cabinet. This may not always agree with room temperature (depend-  
ing on housing construction, installation location, room size, open air tempera-  
tures, etc.). Frequent use of your fireplace will let you determine your own  
comfort levels.  
MANUAL LIGHTING PROCEDURE  
1. Follow steps 1 through 5 under Lighting Instructions, pages 19 and 20.  
2. With control knob pressed in, strike match. Hold match to pilot until pilot  
lights.  
3. Keep control knob pressed in for 30 seconds after lighting pilot. After 30  
seconds, release control knob.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that  
fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper  
installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a
