AIR FOR

COMBUSTION

AND

VENTILATION

 WARNING

This heater shall not be installed in a confined space unless
provisions are provided for adequate combustion and ventilation
air. 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 efficient 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 fuel-burning appliances.

Confined Space and Unconfined Space

The National Fuel Gas Code (ANSIZ2123.1, 1992 Section 5.3) defines a confined
space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour
(4.8 m

3

 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 per hour (4.8 m

3

 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 consid-
ered a part of the unconfined space.

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

PROVIDING ADEQUATE VENTILATION

The following is exerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 5 through 7 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 continu-

ous water vapor retarder with a rating of one perm 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, 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 the three criteria above, you must provide addi-
tional fresh air. See 

Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to page 6.
