B. Standing Pilot Ignition System Wiring

• The standing pilot ignition system wiring DOES NOT
require a 120 VAC supply to operate.
• To power appliance with 120VAC to operate a fan or
remote control, an outlet box may be installed in a bottom
back corner of the existing solid fuel masonry or factory
builtfi replace to plug in the cord assembly or the supplied
power cord may be routed out onto the hearth to a nearby
outlet.
NOTICE: DO NOT wire 120 VAC to the millivolt valve! This
will damage the valve.
• If using a thermostat use one compatible with a millivolt
gas valve system:
- Install the thermostat in the location as indicated in the
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.

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.
• This appliance comes standard with a 120 VAC cord
assembly which has a female plug in to accommodate all
control options and accessories. See Figure 10.5. This
is required for use of optional accessories (standing pilot
ignition) or proper operation of the appliance (IntelliFire
Ignition). An outlet box may be installed in a bottom back
corner of the existing solid fuel masonry or factory built
fi replace to plug in the cord assembly, or the supplied
power cord may be routed out onto the hearth to a nearby
outlet.
• A 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 120 VAC voltage cannot be shared
within the same wall box.
WARNING! Risk of Shock or Explosion! DO NOT wire
120V to the valve or to the appliance wall switch. Incor-
rect wiring will damage controls.
• Determine if the appliance uses an Intellifi re ignition
system or standing pilot ignition system.
• Open the control access panel or remove the decorative
front.
• A red or black ignitor button (as shown in Figure 10.1)
indicates this appliance is standing pilot ignition.

C. IntelliFire Ignition System Wiring

• Wire an outlet box (120VAC) in the bottom back corner of
the existing solid fuel masonry or factory built fi replace to
plug in the cord assembly. The supplied cord assembly
may also be routed out onto the hearth to a nearby outlet.
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 10.2, IPI Wiring Diagram.
• This appliance is equipped with an IntelliFirecontrol valve
which operates on a 3 volt system.
• Plug the 3 volt AC transformer plug into the cord assembly
to supply power to the unit OR install 4 AA 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.
ON/OFF Switch
• An ON/OFF switch is included with the appliance
surround and should be attached to surround/facing.
(See Installation instructions for remote control/fronts).
• If desired an additional wall switch or thermostat may
be added to system.
