3 Volt Transformer

This appliance comes with a factory installed 3 volt trans- former.

Operation with Battery Back-up

This appliance comes with a factory installed battery back- up.

Appliance Requirements

This appliance requires that 110-120 VAC be wired to the factory installed junction box. Maintain correct polarity when wiring the junction box.

!WARNING: DO NOT CONNECT 110-120 VAC TO THE GAS CONTROL VALVE OR THE AP- PLIANCE WILL MALFUNCTION AND THE VALVE WILL BE DESTROYED.

Optional Accessories

Optional remote control kits require that 110-120 VAC be wired to the factory installed junction box before the fire- place is permanently installed.

Heat-Zone and Heat-Out kits are approved with this fire- place as heat management accessories.

Wall Switch

Position the wall switch in the desired position on a wall. Run a maximum of 25 feet (7.8 m) or less length of 18 A.W.G. minimum wire and connect it to the fireplace ON/ OFF switch pigtails.

!WARNING: DO NOT CONNECT 110-120 VAC TO THE WALL SWITCH OR THE CONTROL VALVE WILL BE DESTROYED.

CAUTION: LABEL ALL WIRES PRIOR TO DISCONNEC- TION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERA- TION. VERIFY PROPER OPERATION AFTER SERVICING.
