Continued

Note: 

Your  fireplace is designed to be used

in zero clearance installations. Wall or fram-
ing material can be placed directly against
any exterior surface on the rear, sides, or top
of your  fireplace, except where stand-off
brackets are integrally attached. If stand-off
brackets are attached to your fireplace, these
brackets can be placed directly against wall
or framing materials.

Figure 5 - Installing Hood to Firebox

 CAUTION: This fireplace cre-

ates warm air currents. These cur-
rents move heat to wall surfaces
next to fireplace. Installing fire-
place next to vinyl or cloth wall
coverings or operating fireplace
where impurities (such as to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls.

NOTICE: A qualified service per-
son must install fireplace. Follow
all local codes.

 WARNING: Never install the

fireplace
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,

clothing, or other flammable
objects are less than 36 inches
from the front, top, or sides of
the fireplace

• in high traffic areas
• in windy or drafty areas

NOTICE: This heater is intended
for use as supplemental heat.

mary heat source. If you have a
central heating system, you may

while using heater. This will help
circulate the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
