ADEQUATE COMBUSTION AND VENTILA-
TION AIR
This heater shall not be installed in a confined space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54),
defines a confined space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m
3
per kw) of
the aggregate input rating of all appliances installed in that
pace, 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 considered a part
of a confined space.
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
1 perm (6 x 10
11
kg per pa/sec-m
