aulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and floors, between wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical and gas
lines and other openings.
The following formula can be used to determine the maxi-
mum heater rating per the definition of unconfined space:
BTU/Hr = (L
1
+ L
2
) Ft x (W) Ft x (H) Ft
50
Consider two connecting rooms with an open area
between, with the following dimensions:
L
1
= 15
1
/
2
Ft., L
2
= 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (15
1
/
2
+ 12) x (12) x (8)
50
If there were a door between the two rooms the calculation
would be based only on the room with the heater.
BTU/Hr = (15

/

) x (12) x (8)
