DETERMINING FRESH-AIRFLOWFORHEATERLOCATION
Determining if you haveaConfined orUnconfined Space*
Usethisworksheet todetermine if youhave aconfinedorunconfinedspace.
Space: Includesthe roominwhichyouwillinstallheaterplus anyadjoiningroomswithdoorlesspassageways

1. Determinethe volumeofthespace(length×width×height).
Length×Width×Height= cu.ft. (volumeofspace)
Example: Spacesize20ft. (length)×16ft.( width)×8ft. (ceiling height)=2560cu. ft. (volumeof space)
If additionalventilationtoadjoiningroomissupplied withgrillsoropenings,addthevolumeoftheserooms

2.Dividethespacevolumeby50 cubicfeettodeterminethemaximumBtu/Hrthespacecansupport.
(volumeof space) 50 cu. ft.=(MaximumBtu/Hr thespacecansupport)
Example: 2560 cu. ft. (volumeof space) 50 cu.ft.=51.2or 51.200(maximumBtu/Hr thespacecansupport)
