DeterminingifYou Have aConfined orUnconfined Space
Usethisworksheettodetermineif you have aconfinedor unconfinedspace.
Space: Includesthe roominwhichyouwillinstallheaterplus anyadjoiningroomswithdoorlesspassageways
orventilationgrillsbetweentherooms.
1. Determine thevolumeof thespace(length×width×height).
Length×Width×Height= cu.ft.(volumeofspace)
Example:Spacesize 20ft. (length)×16ft. (width)×8ft. (ceiling height)=2560cu.ft. (volumeofspace)
If additionalventilationtoadjoiningroomissupplied withgrillsor openings,addthevolumeofthese

2.Dividethespacevolumeby50 cubicfeettodeterminethemaximumBtu/Hrthespacecansupport.
(volumeofspace) 50 cu.ft.=(MaximumBtu/Hr the spacecansupport)
Example:2560cu.ft.(volumeofspace) 50cu.ft.=51.2or51,200(maximumBtu/Hr the spacecansupport)
AIRFORCOMBUSTIONANDVENTILATION
