AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall
not be installed in a room or space
unless the required volume of in­door combustion air is provided
by the method described in the

National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable

local codes. Read the following
instructions to insure proper
fresh air for this and other fuel­burning appliances in your home.

Today’s homes are built more energy efcient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out 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

efcient, your home ne eds to breathe. Fresh

air must enter your home. All fuel-burning ap­pliances need fresh air for proper combustion
and ventilation.

Exhaust fans, replaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate 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, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space
The information on pages 8 through 10 will help

you classify your space and provide adequate

ventilation.

Unusually Tight Construction

The air that leaks around doors and windows

may provide enough fresh air for combustion
and ventilation. However, in buildings of un­usually tight construction, you must provide
additional fresh air.

www.SuperiorFireplaces.com

Unusually tight construction is dened as

construction where:
a. walls and ceilings exposed to the out-

side atmosphere have a continuous
water vapor retarder with a rating of

one perm (6 x 10

less with openings 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, between sole plates

and oors, between wall-ceiling joints,

between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.

If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 10.

If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Firebox Location.

Conned and Unconned Space

The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 denes a conned space as a space

whose volume is less than 50 cubic feet per

1,000 Btu per hour (4.8 m3 per kw) of the ag­gregate input rating of all appliances installed

in that space and an unconned space as a
space whose volume is not less than 50 cubic

feet per 1,000 Btu per hour (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicating

directly with the space in which the appliances

are installed*, through openings not furnished

with doors, are considered a part of the un­conned space.

* Adjoining rooms are communicating only if

there are doorless passageways or ventilation
grills between them.

AIR FOR COMBUSTION AND VENTILATION

Continued

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 22 ft. (length) x 18 ft.

(width) x 8 ft. (ceiling height) = 3,168 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 = (Maxi-

mum Btu/Hr the space can support)

Example: 3,168 cu. ft. (volume of space) x 20 =

63,360 (maximum Btu/Hr space can support)

3. Add the Btu/Hr of all fuel burning appliances
in the space.

Vent-free replace _________ Btu/Hr
Gas water heater* _________ Btu/Hr

Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas replace 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.

Example:

Gas water heater _________ Btu/Hr
Vent-free replace + _________ Btu/Hr

Total = _________ Btu/Hr

40,000
39,000
79,000

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: 63,360 Btu/Hr (maximum the

space can support)

79,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the example is a conned space

because the actual Btu/Hr used is more than the

maximum Btu/Hr the space can support. 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

unconned space, remove door to adjoining
room or add ventilation grills between rooms.

B. Vent room directly to the outdoors. See

C. Install a lower Btu/Hr replace, if lower Btu/

Hr size makes room unconned.

www.SuperiorFireplaces.com

If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the

space is an unconned space. You will need

no additional fresh air ventilation.

WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combus­tion and ventilation air shall be
provided by one of the methods
described in the National Fuel

Gas Code, ANSI Z223.1/NFPA 54,

the International Fuel Gas Code,
or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 4). You can also remove door

into adjoining room (see option 3, Figure 4 ).

Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation

grills or ducts.
