The following formula can be used to determine the maximum
heater rating per the definition of unconfined space:
BTU/HR = (L1+L2) Ft x (W) Ft x (H) Ft x 1000
50
Consider two connecting rooms with an open area between,
with the following dimensions:(See Fig. 2, Example)
L1=15-1/2 Ft., L2=12 Ft., W=12 ft., H=8Ft
50
=52800 BTU/HR
If there were a door between the two rooms the calculation
would be based only on the room with the heater.
BTU/HR=(15-1/2) x (12) x (8) x 1000
50
=29760 BTU/HR
