INSTALLING HEATER BASE
ASSEMBLY
CAUTION: Do not remove the
data plates attached to the heater
base assembly. The data plates
contain important warranty and
safety information.
WARNING: You must secure
this heater to fireplace floor. If
not, heater will move when you
adjust controls. Moving heater
may cause a gas leak.
WARNING: If installing in a
sunken fireplace, special care
is needed. You must raise the
fireplace floor to allow access
to heater control panel. This
will insure adequate air flow
and guard against sooting and
controls being damaged. Raise
fireplace floor with noncombus-
tible material. Make sure material
is secure.
CAUTION: Do not pick up
heater base assembly by the
burner. This could damage
heater. Only handle base as-
sembly by grates.

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning fireplace with a working flue and con-
structed of noncombustible material.
For Massachusetts Residents Only:
Instal-
lation of this gas log set as a vented appliance
in the Commonwealth of Massachusetts re-
quires the damper be permanently removed
or welded in the fully open position.
If your heater is a manually-controlled model,
you may use this heater as a vented product.
There are three reasons for operating your
heater in the vented mode.
1. The fireplace does not meet the clearance
to combustibles requirements for vent-
free operation.
2. State or local codes do not permit vent-
free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see
Accessories,
page
27). This will insure vented operation (see Fig-
ure 10). The damper clamp will keep damper
open. Installation instructions are included
with clamp accessory.
See chart for minimum permanent flue open-
ing you must provide. Attach damper clamp
so the minimum permanent flue opening will
be maintained at all times.
