tion ventilation and dilution of flue gases. However, in

buildings of tight construction (for example, weather

stripping, heavily insulated, caulked, vapor barrier, etc.),

additional air may need to be provided using the meth-

ods described in 5.3.3-b or 5.3.4.

Space, Unconfined. For purposes of this Code, a space

whose volume is not less than 50 cubic feet per 1,000

BTU per hour of the aggregate input rating of all

appliances installed in that space. Rooms communicat-

ing directly with the space in which the appliances are

installed through openings not furnished with doors, are

considered a part of the unconfined space.

5.3.3 Equipment Located in Confined Spaces:

(a) All Air from Inside the Building: The confined space

shall be provided with two permanent openings

communicating directly with an additional room(s)

of sufficient volume so that the combined volume of

all spaces meets the criteria for an unconfined space.

The total input of all gas utilization equipment in-

stalled in the combined space shall be considered in

making this determination. Each opening shall have

a minimum free area of 1 square inch per 1,000 BTU

per hour of the total input rating of all gas utilization

equipment in the confined space, but not less than

100 square inches. One opening shall be within 12

inches of the top and one within 12 inches of the

bottom of the enclosure (See Figure 1).

(b) All Air from Outdoors: The confined space shall be

provided with two permanent openings, one com-

mencing within 12 inches of the top and one com-

mencing within 12 inches of the bottom of the enclo-

sure. The openings shall communicate directly, or by

ducts, with the outdoors or spaces (crawl or attic) that

freely communicate with the outdoors.

1. When directly communicating with the outdoors,

each opening shall have a minimum free area of 1

square inch per 4,000 BTU per hour of total input

rating of all equipment in the enclosure (See

Figure 2).

2. When communicating with the outdoors through

vertical ducts, each opening shall have a mini-

mum free area of 1 square inch per 4,000 BTU per

hour of total input rating of all equipment in the

enclosure (See Figure 3).
