Electrical Information

A. Recommendation for Wire
This appliance requires 110-120 VAC to be wired to the junc-
tion box for proper operation of the appliance (Intellifi re igni-
tion).
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.
B. Connecting to the Appliance
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 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.
• Low voltage and 110 VAC voltage cannot be shared within
the same wall box.
C. Intellifi re Ignition System Wiring
This appliance requires a 110 VAC supply to the appliance
junction box for operation. A wiring diagram is shown in Fig-
ure 10.2.
This appliance is equipped with an Intellifi re control valve
which operates on a 3 volt system.
This appliance is supplied with a battery pack and a WSK-
MLT Multi-Function Wall Switch which requires the installa-
tion of the supplied junction box. It is highly recommended
that the junction box be wired at this time to avoid recon-
struction.
The battery pack requires two D cell batteries (not included).
Batteries can be placed in the battery pack at any time.
CAUTION
Battery polarity must be correct or module damage will
occur.

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 10.4).
• Install the supplied Romex™ connector in the cover
plate.
• Feed the necessary length of wire through the
connector.
• 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 appliance:
• Remove the screw attaching the junction box/receptacle to
the outer shell, rotate the junction box inward to disengage
it from the outer shell (see Figure 10.1).
• 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.
