AIR FOR
COMBUSTION AND
VENTILATION
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weatherstripand caulk aroundwindowsand
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.
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
three criteria above, proceed to Deter-
mining Fresh-Air Flow for Heater Lo-
cation on page 5.
Confined and Unconfined
Spaces
The National Fuel Gas Code, ANS Z223.1
defines a confined space as a space whose
volume is less than 50 cubic feet per 1000
Btuperhour(4.8cubicmetersperkw)ofthe
aggregate input rating of all appliances in-
stalledinthatspaceandanunconfinedspace
as a space whose volume is not less than 50
cubic feet per 1000 Btu per hour (4.8 cubic
metersper kw) ofthe aggregateinputrating
of all appliances installed in that space.
Rooms communicating directly with the
spaceinwhichtheappliancesareinstalled*,
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
unlessprovisions areprovided for adequate
combustion and ventilation air.
*Adjoining rooms are communicating only
iftherearedoorlesspassagewaysorventila-
tion grills between them.
WARNING: This heater shall

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 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 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.
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: 46,100 Btu/Hr (maximum the space can support)
50,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/Hrusedis morethanthemaximumBtu/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 adjoining
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.

Example:
Gas water heater 40,000 Btu/Hr
Vent-free heater +10,000 Btu/Hr
Total =50,000 Btu/Hr
WARNING:Iftheareainwhichtheheatermaybeoperatedissmallerthanthatdefinedasanunconfinedspace
or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of
the methods described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
viceperson mustconnectheater
to gas supply. Follow all local
codes.
IMPORTANT: Checkgas line pressurebe-
fore connecting heater to gas line. Gas line
pressure must be no greater than 14 inches
of water. If gas line pressure is higher,
heater regulator damage could occur.
Installation must include an equipment
shutoff valve, ground joint union, and
plugged1/8"NPTtap.LocateNPTtapwithin
reach for test gauge hook up. NPT tap must
be upstream from heater (see Figure 12).
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
fromgoing intopipe. Excesssealant inpipe
could result in clogged heater valves.
Install sediment trap (trap) in supply line as
shown in Figure 12. Locate sediment trap
whereitiswithinreachforcleaning.Locate
sediment trap where trapped matter is not
likelytofreeze. A sedimenttraptraps mois-
ture and contaminants. This keeps them
fromgoing intoheater controls.If sediment
trap is not installed or is installed wrong,
heater may not run properly.
IMPORTANT: Hold pressure regulator
with wrench when connecting it to gas pip-
ing and/or fittings.
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.
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.
