5. For boiler located in a confined space or an unconfined space in a building of unusually tight construction, provide outdoor air. a. Outdoor air for combustion may be provided with an optional Burnham Inlet Air Accessory Kit, Part Number 611280031 (only available and suitable for use on Beckett AFG with burner enclosure cover burner). See Section V for installation details. or b. Outdoor air may be provided with the use of two permanent openings which communicate directly or by duct with the outdoors or spaces (crawl or attic) freely communicating with the outdoors. Locate one opening within 12 inches of top of space. Locate remaining opening within 12 inches of bottom of space. Minimum dimension of air opening is 3 inches. Size each opening per following: i. Direct communication with outdoors. Minimum free area of 1 square inch per 4,000 BTU per hour input of all equipment in space. ii. Vertical ducts. Minimum free area of 1 square inch per 4,000 BTU per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area. iii. Horizontal ducts. Minimum free area of 1 square inch per 2,000 BTU per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area. Alternate method for boiler located within confined space. Use indoor air if two permanent openings communicate directly with additional space(s) of sufficient volume such that combined volume of all spaces meet criteria for unconfined space. Size each opening for minimum free area of 1 square inch per 1,000 BTU per hour input of all equipment in spaces, but not less than 100 square inches. 6. Louvers and Grilles of Ventilation Ducts a. All outside openings should be screened and louvered. Screens used should not be smaller than 1/4 inch mesh. Louvers will prevent the entrance of rain and snow. b. Free area requirements need to consider the blocking effect of louvers, grilles, or screens protecting the openings. If the free area of the louver or grille is not known, assume wood louvers have 20-25 percent free area and metal louvers and grilles have 60-75 percent free area. c. Louvers and grilles must be fixed in the open position, or interlocked with the equipment to open automatically during equipment operation.
