INSTALLING DAMPER CLAMP ACCESSORY
FOR VENTED OPERATION
Note: When used as a vented decorative, appliance must be installed only
in a solid-fuel burning fireplace with a working flue and constructed of non
-
combustible material.
If your heater is a non-thermostatically-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 Figure
10). The damper clamp will keep damper open. Installation instructions 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.

INSTALLING HEATER ASSEMBLY
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. Raise fireplace
floor with non
-combustible material. Make sure material is secure.
CAUTION: Do not pick up heater assembly by logs. This could dam-
age
unit. Only handle assembly by grates.
IMPORTANT: Make sure the heater burners are level. If heater is not level,
heater will not work properly.
