DETERMINING FRESH-AIRFLOWFORHEATERLOCATION
Determining if you HaveaConfined orUnconfined Space*
Usethisworksheet todetermine if youhave aconfinedorunconfinedspace.
Space: Includesthe roominwhichyouwillinstallheaterplus anyadjoiningroomswithdoorlesspassageways
or ventilation grillsbetweentherooms.
1. Determinethe volumeofthespace(length×width×height).
Length×Width×Height= cu.ft. (volumeofspace)
Example: Spacesize18ft.(length)×16ft.( width)×8ft. (ceiling height)=23040cu. ft. (volumeof space)
If additionalventilation toadjoiningroomissuppliedwithgrillsoropenings,addthe volumeofthese
roomstothetotalvolumeofthespace.
2.Divide thespacevolumeby50 cubicfeet todeterminethe maximumBtu/Hr thespacecansupport.
(volumeof space) 50 cu. ft.=(MaximumBtu/Hr thespacecansupport)
Example: 2304 cu. ft. (volumeof space) 50 cu.ft.=46.1or46.100(maximumBtu/Hr thespacecansupport)
