NOTICE: This firebox in com-
bination 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 circulat-
ing blower while using heater.
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 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
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 5.
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 fram
-
ing material can be placed against any exterior
surface on the rear, sides or top of your firebox,
except where standoff spacers are integrally at
-
tached. 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 cre
-
ate the easiest installation (see
Built-In or Internal
Wall Firebox Installation
, page 9).
