The following formula can be used to determine the maximum heater rating per the definition of unconfined space:

BTU/Hr = (L

+ L

) Ft x (W) Ft x (H) Ft
0

Consider two connecting rooms with an open area between, with the following dimensions:

Ft., L

= 1 Ft., W = 1 Ft., H = 8 Ft.

BTU/Hr = (1

+ 1) x (1) x (8)

If there were a door between the two rooms the calculation would be based only on the room with the heater.

unconfined space or if the building is of unusually tight construction, provide adequate

combustion and ventilation air by one of the methods described in the National Fuel

Gas Code, ANSI Z223.1, NFPA54, Section 5.3 or applicable local codes.
