A.  General Information

\WARNING! Risk of Shock! DO NOT

 wire 110-120 VAC 

to the ignition module or to the appliance wall switch.

 

Incorrect wiring will damage controls.

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.

•  Wire the appliance circuit using a minimum 14-2 AWG 

with ground to unswitched 110-120 VAC. This is required 

for use of optional accessories (standing pilot ignition) or 

proper operation of the appliance (IntelliFire™  ignition).

•  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.

•  Low voltage and 110-120 VAC voltage cannot be shared 

within the same wall box.

•  In some instances, the spark ignition of the appliance  

may  cause  intermittent,  non-damaging,  interference 

during the lighting sequence with a TV plugged into the 

same  circuit.      It  is  recommended  that  the  appliance 

and TV use different circuits to mitigate the interference 

potential.    If  interference  is  occurring  on  the  same 

circuit, the use of surge protectors may help alleviate 

the interference.

Accessories Requirements

•  This  appliance  may  be  used  with  a  wall  switch,  wall 

mounted thermostat and/or a remote control.

Wiring for optional Hearth & Home Technologies approved 

accessories should be done now to avoid reconstruction. 

Follow instructions that come with those accessories.

Junction Box Wiring

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 dis

-

engage it from the outer shell.  See Figure 8.1.

•  Pull the electrical wires from outside the appliance through 

the opening into the valve compartment and secure wires 

with a Romex connector. See Figure 8.1.

•  Make all necessary wire connections to the  junction box/

receptacle and reattach the junction box/receptacle to 

the outer shell.

Electrical Service and Repair

WARNING! Risk of Shock! 

Label all wires prior to dis-

connection when servicing controls. Wiring errors could 

cause improper and dangerous operation. Verify proper 

operation after servicing.

WARNING! Risk of Shock! 

Replace damaged wire with 

type 105º C rated wire. Wire must have high temperature 

insulation.
