AIR FOR
COMBUSTION AND

Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weatherstripand caulkaround windowsand
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient,yourhomeneedstobreathe.Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
WARNING: This heater shall

tionair.Readthefollowinginstruc-
tions to insure proper fresh air for
this and other fuel-burning appli-
ances in your home.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
FuelGasCode,ANSIZ223.1/NFPA54,Sec-
tion5.3,AirforCombustionandVentilation.
Allspacesinhomesfallintooneofthethree
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 win-
dows 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 de-
fined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6 x 10-11 kg
per pa-sec-m2) or less with open-
ings 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, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,electrical,and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors , page 7 .
If your home does not meet all of the
threecriteriaabove,proceedto Deter-
mining Fresh-Air Flow For Fireplace
Location , page 6.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION
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.
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 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. 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)
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (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. Direct-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.
_________________ 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)
Thespace intheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
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 adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.
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.
WARNING:Iftheareainwhichtheheatermaybeoperatedissmallerthanthatdefinedasanunconfinedspace
or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of
themethodsdescribedinthe NationalFuelGasCode,ANSIZ223.1/NFPA54,Section5.3 orapplicablelocalcodes.
Example:
Gas water heater 30,000 Btu/Hr
Vent-free fireplace +26,000 Btu/Hr

CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
IMPORTANT: Check gas line pressure
before connecting fireplace to gas line. Gas
line pressure must be no greater than 14
inchesofwater.Ifgaslinepressureishigher,
fireplace regulator damage could occur.
Installation must include an equipment
shutoffvalve, union,and plugged1/8" NPT
tap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream
from fireplace (see Figure 23).
IMPORTANT: Installanequipmentshutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on and
shutting off the gas to the appliance.
Check your building codes for any special
requirementsforlocatingequipmentshutoff
valve to fireplaces.
ApplypipejointsealantlightlytomaleNPT
threads. This will prevent excess sealant
fromgoing into pipe. Excess sealantin pipe
could result in clogged fireplace valves.
We recommend that you install a sediment
trap in supply line as shown in Figure 23.
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
likelytofreeze. Asediment traptraps mois-
ture and contaminants. This keeps them
from going into fireplace controls. If sedi-
ment trap is not installed or is installed
wrong, fireplace may not run properly.
WARNING: Never connect
fireplace to private (non-utility)
gas wells. This gas is commonly
known as wellhead gas.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
yourlocalcodes.Usepipeof1/2"
or greater diameter to allow
propergas volume to fireplace. If
pipe is too small, undue loss of
volume will occur.
CAUTION:Usepipejointseal-
ant that is resistant to liquid pe-
troleum (LP) gas.
* Purchase the optional CSA design-certi-
fied equipment shutoff valve from your
dealer. See Accessories, pages 26 and 27.
