INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
NOTE: When used as a vented heater, appliance must be installed only in a solid-fuel
burning replace with a working ue constructed of noncombustible material. You may
use this heater as a vented product. There are three reasons for operating your heater as
a vented model:
1.
The replace does not meet the clearance 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 ue
damper. You must install the damper clamp accessory (not provided). This will ensure
vented operation (see Figure 9). The damper clamp will keep damper open. Installation
instructions are included with clamp accessory.
