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 Vanguard firebox is designed to
be used in zero clearance installations. 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 fram-
ing materials.
Use dimensions shown for rough openings to
create the easiest installation (see
Built-In or
Internal Wall Firebox Installation
, page 9).
