VENTILATION & COMBUSTION AIR

shall be provided. Ducts may be used to convey 

make-up air from the outdoors and shall have 

the same cross-sectional area of the openings 

to which they are connected.

3. When air for combustion and room ventilation 

is  from  inside  buildings,  the  confined  space 

shall be provided with two permanent openings, 

one starting 12 inches from the top and one 12 

inches from the bottom of the enclosed space. 

Each opening shall have a minimum free area 

of 1 square inch per one thousand (1,000) BTU 

per hour of the total input rating of all appliances 

in the enclosed space, but must not be less 

than one hundred (100) square inches. These 

openings  must  freely  communicate  with  the 

interior areas having adequate infiltration from 

the outside. See 

figure #4

.

4. When the boiler is installed in a confined space 

and all air is provided from the outdoors, the 

confined  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 out-

doors. One of the following methods must be 

used to provide adequate air for ventilation and 

combustion.

A. When directly communicating with the out-

doors, 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
