than or equal to calculated peak heating load (heat loss)

for building or area(s) served by boiler and associated

hot water heating systems� Use heat loss calculations

based on approved methods� See Table 6, page 27�

space shall be provided with two permanent openings,

one commencing within 12 inches from the top and

one commencing 12 inches from the bottom of the

enclosure� The openings shall communicate directly, or

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

that freely communicate with the outdoors� One of the

following methods must be used to provide adequate

air for ventilation and combustion�

A� 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

#3�

6 - VENTILATION & COMBUSTION AIR

B� When communicating with the outdoors by means

of vertical ducts, each opening shall have a

minimum free area 1 square inch per 4,000 Btu per

hour of total input rating of all appliances in the

enclosed space� See Figure #4�

C� If horizontal ducts are used, each opening shall

have a minimum free area 1 square inch per 2,000

Btu per hour total input rating of all appliances in

the enclosed space� See Figure #5�

D� When ducts are used, they shall be of the same

cross sectional area as the free area of the area of

the openings to which they connect� The minimum

dimension of rectangular air ducts shall not be less

than 3 inches�

In calculating free area using louvers, grills or screens

for the above, consideration shall be given to their
