12 Electrical Information

A. Wiring Requirements

NOTICE: 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.

•A 110-120 VAC circuit for this product must be protected with ground-fault circuit-interrupter protection, in compliance with the applicable electrical codes, when it is installed in locations such as in bathrooms or near sinks.

•Wire the appliance junction box to 110-120 VAC. This is required for use of optional accessories (standing pilot ignition) or proper operation of the appliance (Intellifire ignition).

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

•This appliance is inoperable without the WSK-MLT Multi- Function Wall Switch supplied with the appliance.

•See Section D for locating the wall switch to ensure proper operation of the 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.

WARNING! Risk of Shock or Explosion! DO NOT wire 110V to the valve or to the appliance wall switch. Incorrect wiring will damage controls.

B. Intellifire Ignition System Wiring

•Wire the appliance junction box to 110 VAC for proper operation of the appliance.

WARNING! Risk of Shock or Explosion! DO NOT wire IPI controlled appliance junction box to a switched circuit. Incorrect wiring will override IPI safety lockout.

•Refer to Figure 12.2, Intellifire Pilot Ignition (IPI) Wiring Diagram.

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

•Plug the 3-volt AC transformer into the appliance junction box to supply power to the unit OR install two D cell batteries (not included) into the battery pack before use.

NOTICE: Batteries should not be placed in the battery pack while using the transformer. Remove batteries before using the transformer, and unplug the transformer before installing the batteries. Battery polarity must be correct or module damage will occur.

C. Electrical Service and Repair

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

WARNING! Risk of Shock! Replace damaged wire with type 105° C rated wire. Wire must have high temperature insulation.

D. Junction Box Installation

If the box is being wired from the OUTSIDE of the appli- ance:

•Remove the cover plate located on the outer shell - right side (see Figure 12.1).

•Install the supplied Romex™ connector in the cover plate.

•Make all necessary wire connections and reattach the cover plate to the outer shell.

If the box is being wired from the INSIDE of the appli- ance:

•Remove the screw attaching the junction box/receptacle to the outer shell, rotate the junction box inward to disengage it from the outer shell.

•Pull the electrical wires from outside the appliance through this opening into the valve compartment.

•Feed the necessary length of wire through the connector.

•Make all necessary wire connections to the junction box/ receptacle and reassemble the junction box/receptacle to the outer shell.
