Hearth Dimensions and Firebox Locations
FIREBOX LOCATION
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 in Section 6.
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 5.2 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.
