free area of 1 sq. in./1000 Btu/hr of the

 

total input rating of all gas utilization

 

equipment in the space, but not less than

 

100 sq. inches. One opening shall com-

 

mence within 12 inches of the top, and

 

one opening shall commence within 12

 

inches of the bottom of the enclosure.

 

-Combining spaces in different stories. The volumes of spaces in different sto- ries shall be considered as communicat- ing spaces where such spaces are con- nected by one or more openings in doors or floors having a total minimum free area of 2 sq. in./1000 Btu/hr of total input rating of all gas utilization equipment.

Outdoor Combustion Air

BEST PRACTICE

Isolating the combustion appliance room from the rest of the building and bring- ing in uncontaminated outside air for combustion and ventilation is always preferred.

Openings used to supply combustion and ven- tilation air shall be sized and located in accor- dance with the following:

One Permanent Opening Method.

One permanent opening, commencing within 12 in. of the top of the enclosure, shall be provided. The equipment shall have clearances of at least 1 inch from the sides and back and 6 in. from the front of the appliance. The opening shall direct- ly communicate with the outdoors or shall com- municate through a vertical or horizontal duct to the outdoors or spaces that freely communicate with the outdoors and shall have a minimum free area of the following:

-1sq. in./3000 Btu/hr of the total input rating of all equipment located in the enclosures, and

Fig. 2: Equipment Located in Confined Spaces; One Permanent Air Inlet

Two Permanent Openings Method.

Two permanent openings, one commencing within 12 in. of the top and one commencing within 12 in. of the bottom of the enclosure, shall be provided. The openings shall commu- nicate directly, or by ducts, with the outdoors or spaces that freely communicate with the out- doors, as follows:

-Where directly communicating with the outdoors or where communication to the outdoors is through vertical ducts, each opening shall have a minimum free area of 1 sq. in./4000 Btu/hr of total input rat- ing of all equipment in the enclosure. See Fig. 3 page 10.

-Where communicating with the out- doors is through horizontal ducts, each opening shall have a minimum free area of not less than 1 sq.in./2000 Btu/hr of total input rating of all equipment in the enclosure. See Fig.4 page 10.
