AIR FOR
COMBUSTION AND
VENTILATION
WARNING: Thls heater shall
not be installed In a confined
space unless provlslons are pro-
vlded for adequate combustion
and ventilation air. Read the fol-
lowing Instructions to Insure
proper fresh air for thls and other
fuel-bumlng appliances In your
home.
Today's homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new constniction methods
help reduce heat loss in homes. Home owners
weather stripand caulk aroundwindows and
doors tokeep the cold airout 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 tobreathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustiun and ventilation.
Exhaust fans, fn'eplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air fur these appliances. This
will insure proper venting of vented fuel-
bunting appliances.
PROVIDING ADEQUATE
VENTILATION
The following is excerpts from National
Fuel Gas Code. NFPA 54/ANSl Z223.1,
Section 5.3, Air for Combustion and Venti-
lation.
Allspaces in homes fall into one ofthe three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 4through 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-
tlnuous water vapor retarder wlth
aretlng of one perm (6 x 10-" kg
per pe.sec-m =)or less wlth open-
Ings gasketed or sealed and
b. weather atrlpplng has been
added on openable windows and
doors and
c. caulking or sealants are applled
to areas such as lolnts around
wlndow end door frames, be-
tween sole plates and floors, be-
tween well-ceiling Jolnts, be-
tween wall panels, at penetra-
tlons for plumblng, electrical, and
gas llnes, and at other oponlngs.
If your home meats 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 meat all of the
three crltada above, proceed to Deter-
mining Frssh-AIr Flow for Heater Lo-
eatlon on page 5.
Confined and Unconfined
Spaces
The National Fuel Gas Code (ANSI Z223.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubic feet per 1000 Btu per hour (4.8 cubic
meters per kw) of the aggregate input rating
of all appliances installed in that space and
an unconfined space as a space whose vol-
ume is not less than 50 cubic feet per 1000
Btu per hour (4.8 cubic meters per kw) of the
aggregate input rating of all appliances in-
stalled inthat space. Rooms communicating
directly with the space in which the appli-
ances are installed*, through openings not
furnished with doors, are considered a part
of the unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
*Adjoining rooms are communicating only
ifthere are doorless passageways or ventila-
tion grills between them.

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: Includes the room in which you will install heater 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 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling heigh 0 = 2304 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: 2304 cu. ft. (volume of space) + 50 cu. ft. = 46.1 or 46,100 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space,
Vest-free heater Btu/Hr
Gas water heater* Btu/Hr Example:
Gas furnace Btu/Hr Gas water heater 40,000 Btu/Hr
Vented gas heater Btu/Hr Vent-free heater +10,000 Btu/Hr
Gas fireplace logs Btu/Hr Total = 50,000 Btu/Hx
Other gas appliances* + Btu/Hr
Total =Bto/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 BttffHr 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: 46,100 Btu/Hr (maximum the space can support)
50,000 Bto/Hr (actual amount of Btu/Hr used)
The space in the above example is aconfined space because the actualBtu/Hr used is more thanthe max'maumBtu/Hr the space cansupport.
You must provide additional fresh air. Your options are as follows:
A, Rework worksbeet, 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. lustall alower Bto/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.
I Ak WARNING: ifthe area in which the heater may be operated is smaller than that defined asen uncenflned space,
provide adequate combustion and ventilation sir by one of the methods described in the NatIonalFuel Gas Code,
ANSI Z223.1, 1992, Section 5.3 or applicable local codes.

CONNECTING TO GAS
SUPPLY
NOTICE: A qualified service per-
son must connect heater to gas
supply. Follow all local codes.
_k CAUTION: Never connect
heater directly to the propane/LP
supply. This heater requires an
external regulator (not supplied).
Install the external regulator be-
tween the heater and propane/I.P
supply.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
12. Pointing the vent down protects it from
freezing rain or sleet.
Installation must include a manual shutoff
valve, ground joint 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 13).
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 heater valves.
_CAUTION: Use plpejolnt seel-
ant that Is resistant to liquid pe-
troleum (LP) gas.
3/8"NP
Ground Joint Union
Install sediment trap insupply line asshown
inFigure 13. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter 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.
