LOCATION OF FIREBOX
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 .
See “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 .
• Minimize modifications to existing construction . Refer to
Figure 2 below for location suggestions .
• Do not install in the vicinity where gasoline or other
flammable liquids may be stored . The vent-free firebox
must be kept clear and free from these combustible
materials .
