FIREPLACE

INSTALLATION

NOTICE: This heater is intended

for use as supplemental heat. Use

this heater along with your pri-

mary heating system. Do not in-

stall this heater as your primary

heat source. If you have a central

heating system, you may run

system’s circulating blower while

using heater. This will help circu-

late the heat throughout the

house. In the event of a power

outage, you can use this heater

as your primary heat source.

NOTICE: A qualified service per-

son must install fireplace. Follow

all local codes.

 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.

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

spacers are integrally attached. If stand-off

spacers are attached to your fireplace, these

spacers can be placed directly against wall

or framing material. See framing details on

page 4.

Place the fireplace into position and shim

with noncombustible material if needed.

Nail the side flanges to the framing to secure

the unit in place. There are two floor brack-

ets included with each unit. Use these as an

alternative method of securing the fireplace.

IMPORTANT: 

Make sure fireplace is level

before securing. If fireplace is not level it

will not work properly.
