AIR FOR
COMBUSTION AND
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-m

2

) 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-
tions for plumbing, 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 

De-

termining Fresh Air Flow For Heater
Location, page 5.

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 com-
bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, 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.

 WARNING: This heater shall

not be installed in a confined
space unless provisions are pro-
vided for adequate combustion
and ventilation air. Read the fol-
lowing instructions to insure
proper fresh air for this and other
fuel-burning appliances in your
home.

PROVIDING ADEQUATE
VENTILATION

The following is exerpts from National
Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Venti-
lation.

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 4 through 6 will
help you classify your space and provide
adequate ventilation.

Confined and Unconfined Space

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 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 in-
stalled*, 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
if there are doorless passageways or ventila-
tion grills between them.
