NOTICE: If your installation does
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel.
FLOOR CLEARANCES
A. If installing appliance on the floor level, you
must maintain the minimum distance of 14"
to combustibles (see Figure 8).
B. If combustible materials are less than 14" to
the fireplace, you must install appliance at
least 5" above the combustible flooring (see
Figure 9).

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
Note:
When used as a vented heater, appliance
must be installed only in a solid-fuel burning fire-
place with a working flue and constructed of non-
combustible material.
If you choose to use your heater as a manually-
controlled model (no remote control installed), 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 op-
eration.
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 34). This will insure vented
operation (see Figure 10, page 12). The damper
clamp will keep damper open. Installation instruc-
tions are included with clamp accessory.
See chart below for minimum permanent flue
opening you must provide. Attach damper clamp
so the minimum permanent flue opening will be
maintained at all times.
