FLOOR CLEARANCES
A. If installing appliance on the floor level, you

fireplace, you must install appliance at least 5"
above the combustible flooring (see Figure 10).
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 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 com-
bustibles 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 or-
der, see Accessories, page 43). This will insure
vented operation (see Figure 11). The damper
clamp will keep damper open. Installation instruc-
tions are included with clamp accessory.
