Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weatherstripandcaulkaround windowsand

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.
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
notbeinstalledinaconfinedspace
or unusually tight construction
unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code, NFPA 54/ANS Z223.1, Sec-
tion5.3,AirforCombustionandVentilation.
Allspacesinhomesfallintooneofthethree
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 4 through 6 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 6 .
If your home does not meet all of the
threecriteriaabove,proceedto Deter-
mining Fresh-Air Flow for Heater Lo-
cation, page 5.
Confined and Unconfined Space
The National Fuel Gas Code, ANS Z223.1
defines a confined space as a space whose
volume is less than 50 cubic feet per 1,000
Btu per hour (4.8 m3per kw) of the aggre-
gate input rating of all appliances installed
in that space and an unconfined space as a
space whose volume is not less than 50
cubicfeetper1,000Btuperhour(4.8m3per
kw) of the aggregate input rating of all
appliances installed in that space. Rooms
communicating directly with the space in
whichtheappliancesareinstalled*,through
openings not furnished with doors, are con-
sidered a part of the unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unlessprovisionsare provided foradequate
combustion and ventilation air.

DETERMINING FRESH-AIR FLOW FOR HEATER 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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween
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. 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. = 51.2 or 51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater ______________ 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)
73,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/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 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.
C. Install a lower Btu/Hr heater, 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.

CLAMP ACCESSORY FOR
VENTED OPERATION
Note: When used as a vented heater, appli-
ance must be installed only in a solid-fuel
burning fireplace with a working flue and
constructed of noncombustible material.
If your heater is a manually-controlled
model, you may use this heater as a vented
product. There are three reasons for operat-
ing your heater in the vented mode.
1. The fireplace does not meet the clear-
ance to combustibles requirements for
vent-free operation.
2. State or local codes do not permit vent-
free operation.
3. You prefer vented operation.
Ifreasonsnumber1or2aboveapplytoyou,
you must permanently open chimney flue
damper.Youmustinstallthe damperclamp
accessory (to order, see Accessories, page
24). This will insure vented operation (see
Figure 10). The damper clamp will keep
damper open. Installation instructions are
included with clamp accessory.
See chart below for minimum permanent
flue opening you must provide. Attach
damper clamp so the minimum permanent

Installation Items Needed
Beforeinstallingheater,makesureyouhave
the items listed below.
• external regulator (supplied by installer,
see Figure 13)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap

WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.
Installation must include an equipment
shutoffvalve,union, andplugged 1/8"NPT
tap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream
from heater (see Figure 14).
IMPORTANT: Installanequipmentshutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
fromgoingintopipe. Excesssealantinpipe
could result in clogged heater valves.
CAUTION:Usepipejointseal-
ant that is resistant to liquid pe-
troleum (LP) gas.
We recommend that you install a sediment
trap in supply line as shown in Figure 14.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
betweenfuelsupplyandheater.Locatesedi-
menttrapwheretrappedmatter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.
CAUTION: Avoid damage to
gascontrol.Holdgascontrolwith
wrenchwhenconnectingittogas
piping and/or fittings.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incominggaspressuretobetween11and14
inchesofwater.Ifyoudonotreduceincom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
