Carefully select the best location for installation of your
vent-free firebox. The following factors should be taken
into consideration:
•
Clearance to side wall, ceiling, woodwork and windows.
Refer to “Clearances/Height Requirements on Page 8.
Minimum clearances to combustibles
must be main-
tained.
•
Location must not be affected by drafts caused by
kitchen exhaust fans, ceiling fans, return air registers
for forced air furnaces / air conditioners, windows or
doors.
•
Installation must provide adequate ventilation and com-
bustion air.
•
Location should be out of high traffic or windy or drafty
areas.

DO NOT INSTALL WHERE CURTAINS, FURNITURE,
CLOTHING OR OTHER FLAMMABLE OBJECTS ARE
LESS THAN 42" FROM FRONT OF HEATER.

Never obstruct the front opening of the vent-free firebox
or restrict the flow of combustion and ventilation air.
