CAUTION: Log heaters
installed in this firebox create
warm air currents. These cur-
rents move heat to wall surfaces
next to firebox. Installing firebox
next to vinyl or cloth wall cover-
ings or operating firebox where
impurities (such as, but not
limited to, tobacco smoke, aro-
matic candles, cleaning fluids,
oil or kerosene lamps, etc.) in
the air exist, may discolor walls
or cause odors.
IMPORTANT:
Vent-free gas log heaters add
moisture to the air. Although this is beneficial,
installing firebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See
Air for Combustion
and Ventilation
, page 7.
WARNING: A qualified ser-
vice person must install firebox.
Follow all local codes.
WARNING: Never install the
firebox
• in a bedroom or bathroom*
• in a recreational vehicle
• where curtains, furniture,
clothing or other flammable
objects are less than 42" from
the front, top or sides of the
firebox
• in high traffic areas
• in windy or drafty areas
* Unless the installed log set is
rated at 10,000 Btu/Hr or less.
