®

CHECK GAS TYPE

Use proper gas type for the fireplace unit
you are installing. If you have conflicting
gas types, do not install fireplace. See dealer
where you purchased the fireplace for proper
fireplace according to your gas type.

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.

 WARNING: A qualified ser-

vice person 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 framing
material can be placed directly against any
exterior surface on the rear, sides, or top of
your fireplace, except where standoff spacers
are integrally attached. If standoff spacers are
attached to your fireplace, these spacers can be
placed directly against wall or framing mate-
rial. See framing details on pages 4 and 5.

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.
