OUTDOOR AIR THROUGH TWO HORIZONTAL

DUCTS

FIGURE 13. FRESH AIR FROM TWO HORIZONTAL DUCTS

The confined space shall be provided with two permanent

horizontal ducts, one commencing within 12 inches (300

mm) of the top and one commencing within 12 inches

(300 mm) of the bottom of the enclosure. The horizontal

ducts shall communicate directly with the outdoors. See

.

Each duct opening shall have a minimum free area of 1

square inch per 2,000 Btu/hr (1100 mm

2

per kW) of the

aggregate input rating of all appliances installed in the

enclosure.

When ducts are used, they shall be of the same cross

sectional area as the free area of the openings to which

they connect. The minimum dimension of rectangular air

ducts shall be not less than 3 inches.

OUTDOOR AIR THROUGH TWO VERTICAL DUCTS

The illustrations shown in this section of the manual are

a reference for the openings that provide fresh air into

confined spaces only.

DO NOT

refer to these illustrations for the purpose of

vent installation. See

for complete

venting instructions.

The confined space shall be provided with two permanent

vertical ducts, one commencing within 12 inches (300

mm) of the top and one commencing within 12 inches

(300 mm) of the bottom of the enclosure. The vertical

ducts shall communicate directly with the outdoors. See

Each duct opening shall have a minimum free area of 1

square inch per 4,000 Btu/hr (550 mm

2

per kW) of the

aggregate input rating of all appliances installed in the

enclosure.

When ducts are used, they shall be of the same cross

sectional area as the free area of the openings to which

they connect. The minimum dimension of rectangular air

ducts shall be not less than 3 inches.

AIR FROM OTHER INDOOR SPACES

The confined space shall be provided with two permanent
