INSTALLATION
NOTICE: This firebox in combination with unvented
log sets are intended for use as supplemental heat.
Use along with your primary heating system. Do not
install them as your primary heat source. If you have
a central heating system, you may run system’s cir
-
culating blower while using appliance. This will help
circulate the heat throughout the house. In the event
of a power outage, you can use unvented logs as your
primary heat source.
WARNING: A qualified service 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 flam
-
mable objects are less than 42" from the front, top
or sides of the firebox
• in high traffic areas
• in windy or drafty areas
CAUTION: Log appliances installed in this firebox
create warm air currents. These currents move heat
to wall surfaces next to firebox. Installing firebox next
to vinyl or cloth wall coverings or operating firebox
where impurities (such as, but not limited to, tobacco
smoke, aromatic candles, cleaning fluids, oil or kero-
sene lamps, etc.) in the air exist, may discolor walls
or cause odors.
IMPORTANT:
Vent-free gas log appliances 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 6.
IMPORTANT:
Make sure the firebox is level. If firebox is not level, log
set will not work properly.
Note: Your firebox is designed to be used in zero clearance instal-
lations. Wall or framing material can be placed against any exterior
surface on the rear, sides or top of your firebox, except where standoff
spacers are integrally attached. If standoff spacers are attached to
your firebox, these spacers can be placed directly against wall or
framing materials.
Use dimensions shown for rough openings to create the easiest
installation (see Built-In Firebox Installation, page 9).
