foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods

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.
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-
tionsfor plumbing,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
three criteria above, proceed 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
unlessprovisionsareprovidedforadequate
combustion and ventilation air.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet 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)
54,000 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.

CONNECTING TO GAS
SUPPLY
WARNING:Aqualifiedservice
person must connect heater to
gassupply.Followalllocalcodes.
Theinstallermustsupplyanexternalregulator.
The external regulator will reduce incoming
gas pressure. You must reduce incoming gas
pressure between 11 and 14 inches of water. If
youdonotreduceincominggaspressure,heater
regulator damage could occur. Install external
regulatorwiththeventpointingdownasshown
inFigure 13.Pointingtheventdown protectsit
from freezing rain or sleet.
Installsedimenttrapinsupplylineasshown
in Figure 14. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
menttrap where trapped matter isnot 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.
IMPORTANT: Holdpressureregulatorwith
wrench when connecting it to gas piping
and/or fittings
Installation must include an equipment
shutoffvalve,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 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. Excess sealant in pipe
could result in clogged heater valves.
CAUTION:Neverconnectheater
directly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe 3/8"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
CAUTION:Usepipejointseal-
