INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION

Note: When used as a vented heater, appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of noncombustible material.

If you choose to use your heater as a manually-controlled model (no remote control installed), 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 re- quirements 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 26). 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 BASE ASSEMBLY

visit CAUTION: Do not remove the data plates attached to the heater base assembly. The data plates contain important warranty and safety information.

Manual background WARNING: You must secure this heater to fire- place floor. If not, heater will move when you adjust controls. Moving heater may cause a gas leak.

Manual backgroundWARNING: 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 and con- trols being damaged. Raise fireplace floor with non- combustible material. Make sure material is secure.

Manual background CAUTION: Do not pick up heater base assembly by the burner. This could damage heater. Only handle base assembly by grates.
