Ventilation of boiler room must be adequate enough toprovide sufficient air to properly support combustion,venting and maintain safe ambient temperatures undernormal operating conditions.2. When the boiler is located in an unconfined space in abuilding of conventional construction frame, masonryor metal, infiltration normally is adequate to provideair for combustion and ventilation. However, in anybuilding which has been altered to conserve energyor to minimize infiltration, the boiler area shouldbe considered as a confined space. If there is anydoubt, install air supply provisions for combustionand ventilation in accordance with Chapter 5, Air forCombustion and Ventilation, of NFPA 31, Standardfor the Installation of Oil Burning Equipment. Therecommendations that follow, or applicable provisionsof the local building codes.3. When the boiler is installed in an unconfined space,in a building of unusually tight construction, air forcombustion and room ventilation must be obtainedfrom outdoors or from spaces freely communicatingwith the outdoors. A permanent opening or openingshaving a total free area of not less than 1 square inchper 5,000 BTU per hour of total input rating of allappliances shall be provided. Ducts may be used toconvey make-up air from the outdoors and shall havethe same cross-sectional area of the openings to whichthey are connected.4. When air for combustion and room ventilation is frominside buildings, the confined space shall be providedwith two permanent openings, one starting 12 inchesfrom the top and one 12 inches from the bottom of theenclosed space. Each opening shall have a minimumfree area of 1 square inch per 1,000 BTU per hour ofthe total input rating of all appliances in the enclosedspace, but must not be less than 100 square inches.These openings must freely communicate with theinterior areas having adequate infiltration from theoutside.

VENTILATION AND COMBUSTION AIR5. When the boiler is installed in a confined space andall air is provided from the outdoors, the confinedspace shall be provided with two permanent openings,one commencing within 12 inches from the top andone commencing 12 inches from the bottom of theenclosure. The openings shall communicate directly, orby ducts, with the outdoors or spaces (crawl or attic)that freely communicate with the outdoors. One of thefollowing methods must be used to provide adequateair for ventilation and combustion.A. When directly communicating with the outdoors,each opening shall have a minimum free area of 1square inch per 4,000 BTU per hour of total inputrating of all equipment in the enclosure. (Figure#4)B. When communicating with the outdoors by meansof vertical ducts, each opening shall have aminimum free area 1 square inch per 4,000 BTUper hour of total input rating of all appliances in theenclosed space. (Figure #5)C. If horizontal ducts are used, each opening shallhave a minimum free area 1 square inch per 2,000BTU per hour total input rating of all appliances inthe enclosed space. (Figure #6)D. When ducts are used, they shall be of the samecross sectional area as the free area of the area ofthe openings to which they connect. The minimumdimension of rectangular air ducts shall not be lessthan 3 inches.6. In calculating free area using louvers, grills or screensfor the above, consideration shall be given to theirblocking effect. Screens used shall not be smaller than1/4 inch mesh. If the free area through a design oflouver or grill is known, it should be used in calculatingthe size opening required to provide the free areaspecified. If the design and free area is not known, itmay be assumed that wood louvers will have 20-25%free area and metal louvers and grills will have 60-75%free area. Louvers and grills shall be fixed in the openposition or interlocked with the boiler so that they areopened automatically during boiler operation.Figure #4Figure #5Figure #67
