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 fire-

box next to vinyl or cloth wall

coverings or operating firebox

where impurities (such as, but

not limited to, tobacco smoke,

aromatic candles, cleaning flu-

ids, 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

create the easiest installation (see Built-In Firebox

Installation, page 9).
