10 Electrical Information

A. Recommendation for Wire

This appliance requires 110-120 VAC to be wired to the junc- tion box either for use of optional accessories (standing pilot ignition) or for proper operation of the appliance (Intellifire ignition).

Open the control access panel to view wiring system and gas valve. If this appliance has a red or black ignitor button this appliance has a standing pilot ignition system. If there is no red or black ignitor button, this appliance has an Intellifire ignition system.

Note: This appliance must be electrically wired and grounded in accordance with local codes or, in the absence of local codes, with National Electric Code ANSI/NFPA 70-latest edition or the Canadian Electric Code CSA

C22.1.

WARNING

Shock Risk

Explosion Risk

Do NOT wire 110V to valve.

Do NOT wire 110V to wall switch

•Incorrect wiring will damage millivolt values.

•Incorrect wiring will override IPI safety lockout and may cause explosion.

•This appliance may be used with a wall switch, wall mounted thermostat and/or a remote control.

•If using thermostat use one compatible with a millivolt gas valve system.

•Follow parameters for locating thermostat (see individual thermostat instructions) to ensure proper operation of appliance.

•Use low resistance thermostat wire for wiring from ignition system to the wall switch and thermostat.

•Keep wire lengths short as possible by removing any excess wire length.

•Low voltage and 110 VAC voltage cannot be shared within the same wall box.

C. Intellifire Ignition System Wiring

This appliance requires a 110 VAC supply to the appliance junction box for operation. (See Figure 10.1 for a wiring dia- gram and Figure 10.3 for junction box wiring.)

This appliance is equipped with an Intellifire control valve which operates on a 3 volt system.

This appliance is supplied with a battery pack and a 3 volt AC transformer, which requires the installation of the sup- plied junction box. It is highly recommended that the junction box be installed at this time to avoid reconstruction.

The battery pack requires two D cell batteries (not included). Batteries cannot be placed in the battery pack while using the 3 volt AC transformer. Conversely, the transformer must be unplugged if the battery pack is used.

CAUTION

Battery polarity must be correct or module damage will occur.

Optional Accessories Requirements

Wiring for optional accessories should be done now to avoid reconstruction.

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

CAUTION

Shock Risk

•Replace damaged wire with type 105° C rated wire.

•Wire must have high temperature insulation.
