LOCATION OF FIREBOX
Carefully select the best location for installation of your
vent-free fi rebox. 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 maintained.
• 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
combustion air.
•
DO NOT INSTALL THIS FIREBOX IN A BED-
ROOM OR BATHROOM.
• Location should be out of high traffi c or windy or
drafty areas.
•
DO NOT INSTALL WHERE CURTAINS, FURNITURE, CLOTHING OR OTHER FLAMMABLE OBJECTS

• Never obstruct the front opening of the vent-free fi rebox or restrict the fl ow of combustion and ventilation air.
• Minimize modifi cations to existing construction. Refer to Figure 3 below for location suggestions.
