NOTICE

Clearance to venting is for single wall vent pipe. If Type L vent is used, clearance may be reduced to the minimum required by the vent pipe manufacturer.

C.PROVIDE COMBUSTION AND VENTILATION AIR. Local and National Codes may apply and should be referenced.

WARNING

Adequate combustion and ventilation air must be provided to assure proper combustion and to maintain safe ambient air temperatures.

Do not install boiler where gasoline or other flammable vapors or liquids, or sources of hydrocarbons (i.e. bleaches, fabric softeners, etc.) are used or stored.

Do not install boiler in laundry room, or, in vicinity of clothes dryer to prevent inadequate air supply to burner and lint contamination of burner air intake openings.

1.Determine volume of space (boiler room). Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the space.

Volume(ft3) = Length(ft) x Width(ft) x Height(ft)

2.Determine total input of all appliances in the space.

Add inputs of all appliances in the space and round the result to the nearest 1000 BTU per hour.

3.Determine type of space. Divide Volume by total input of all appliances in space. If the result is greater than or equal to 50 ft3/1000 BTU per hour, then it is considered an unconfined space. If the result is less than 50 ft3/1000 BTU per hour then the space is considered a confined space.

4.For boiler located in an unconfined space of a conventionally constructed building, the fresh air infiltration through cracks around windows and doors normally provides adequate air for combustion and ventilation.

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.
