The following formula can be used to determine the maximum heater rating (per the definition of unconfined space) that is al-
lowed in your space:
Maximum BTU/Hr. =
x 1000
Example A: Consider two connecting rooms with an open area between, with the following dimensions: L1 = 151/2 ft., L2 = 12 ft., W
= 12 ft., H = 8 ft.
x
1000
=
52,800
BTU/Hr.
Example B: If there were a door between the two rooms the calculation would be based only on the room with the heater.
x 1000 = 29,760 BTU/Hr.

Bringing in Outside (or “Make-up”) Air
Many building code jurisdictions require that outside or “make-up” air be provided when installing a fireplace of this type. This
requirement can be satisfied by the proper installation of an ‘outside air kit’ which is not provided. The final determination of the
suitability of any particular kit must be made by the installer.
If an outside air supply is desired it should be added to the room in which the
H Series
Vent Free Gas Fireplace is installed,
not to
the chase
enclosing the fireplace.
If outside air is introduced into the chase, competing air pressures could compromise the operation of the fireplace.
