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 fuel-burning 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 efficient, your home needs
to breathe. Fresh air must enter your home. All fuel-burning appliances
need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, 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 fuel­burning 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
classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space
The information on pages 5 through 6 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.

Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the outside atmosphere have a

continuous water vapor retarder with a rating of one perm (6 x

-11

10

kg per pa-sec-m2) or 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 floors, 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 these three criteria, you must provide ad­ditional fresh air. See Ventilation Air From Outdoors, page 6.

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

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined
space as a space whose volume is less than 50 cubic feet per 1,000
Btu/hr (4.8 m3 per kw) of the aggregate input rating of all appliances
installed in that space and an unconfined space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu/hr (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 unconfined space.

* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.

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: Includes the room in which you will install fireplace 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 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. Multiply the space volume by 20 to determine the maximum Btu/
Hr the space can support.

_______ (volume of space) x 20 = (Maximum Btu/Hr the space

can support)

Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum

Btu/Hr the space can support)

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

Vent-free fireplace 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.

Example:
Gas water heater 40,000 Btu/Hr
Vent-free fireplace + 30,000 Btu/Hr
Total = 70,000 Btu/Hr

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)
70,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined 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 unconfined space, remove door to adjoin­ing room or add ventilation grills between rooms. See Ventilation
Air From Inside Building.

B. Vent room directly to the outdoors. See Ventilation Air From

Outdoors.

C. Install a lower Btu/Hr fireplace, 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.

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 From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling and
one within 12" of the floor. Connect these items directly to the out­doors or spaces open to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation for required size of
ventilation grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic
if attic has a thermostat-controlled power vent. Heated air entering
the attic will activate the power vent.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined space. When
ventilating to an adjoining unconfined space, you must provide two
permanent openings: one within 12" of the ceiling and one within
12" of the floor on the wall connecting the two spaces (see options
1 and 2, Figure 2). You can also remove door into adjoining room
(see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation for required size
of ventilation grills or ducts.
