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 con- structed of noncombustible material.

If your heater is a non-thermostatically-controlled model, you may use this heater as a vented product. There are three reasons for oper- ating 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 ac- cessory (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 noncombustible material. Make sure material is secure.

CAUTION: Do not pick up heater assembly by logs. This could damage unit. Only handle assembly by grates.

IMPORTANT: Make sure the heater burners are level. If heater is not level, heater will not work properly.
