Unvented (vent-free) universal firebox

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 impuri-
ties (such as, but not limited to, to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
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 benefi-
cial, 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 installations. Wall or framing
material can be placed against any exte-
rior 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).
