FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: This heater shall not be installed in a
confi ned space or unusually tight construction un-
less provisions are provided for adequate combus-
tion and ventilation air. Read the following instruc-
tions to insure proper fresh air for this and other
fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com-
bustion and Ventilation. All spaces in homes fall into
one of the three following ventilation classifi cations:
1. Unusually Tight Construction
2. Unconfi ned Space
3. Confi ned Space
This heater must not be installed in a confi ned space or
unusually tight construction unless provisions are pro-
vided for adequate combustion and ventilation air. The
information on pages 4 through 6 will help you classify
your space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you
must provide additional fresh air. See Ventilation Air
from Outdoors, page 6.
Unusually tight construction is defi ned as construction
where:
a. Walls and ceilings exposed to the outside atmo-
sphere have a continuous water vapor retarder with
a rating of one perm (6 x 10
less with openings gaskets or sealed and
b. Weather stripping has been added on openable win-
dows and doors, and
c. Caulking or sealants are applied to areas such as
joints around windows and door frames, between
wall-ceiling joints, between wall panels, at penetra-
tions for plumbing, electrical, and gas lines, and at
other openings.
If your home does not meet all of the three criteria
above, see Determing the Type of Heater Location
Space, page 5.
Confi ned Space and Unconfi ned Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
defi nes a confi ned space as a space whose volume is
less than 50 cubic feet per 1,000 Btu per hour (4.8 m
per kW) of the aggregate input rating of all appliances
installed in that space, and an unconfi ned space as a
space whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m
input rating of all appliances installed in that space.
Rooms communicating directly with the space in which
the appliances are installed*, through openings not fur-
nished with doors, are considered a part of the uncon-
fi ned space.
