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.

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.
