DETERMINING FRESH-AIR FLOW FOR
DETERMINE IF YOU HAVE UNUSUALLY TIGHT CONSTRUCTION OR UNCONFINED SPACE
Use this worksheet to determine if you have unusually tight construction or unconfined space.
SPACE: Includes the room in which you will install heater plus adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height =_________cu.ft.(volume of space)
EXAMPLE: 20 ft.(Length) x 16 ft.(Width) x 8 ft.(ceiling Height)=
2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the
volume of these rooms to the total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr the
space can support.
_________(volume of space)/50 cu. ft. =maximum BTU/Hr the space can support)
EXAMPLE: 2560 cu. ft. (volume of space /50 cu. Ft .= 51.2 or
51200 (maximum BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel burning appliances in the space.
