FIREBOX LOCATION

Carefully select the best location for installation of your

vent-free rebox. The following factors should be taken

into consideration:

• Clearance to side wall, ceiling, woodwork and windows.

See “Clearances/Height Requirements on page 8. Mini-

mum 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 com-

bustion air.

• Location should be out of high trafc 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 rebox

or restrict the ow of combustion and ventilation air.

• Minimize modications to existing construction. Refer

to Figure 5.2 for location suggestions.

• Do not install in the vicinity where gasoline or other

ammable liquids may be stored. The vent free rebox

must be kept clear and free from these combustible

materials.
