For Intermittent Pilot Ignition (IPI) Wiring
Appliance Requirements
This appliance requires that 110-120 VAC be wired to the
junction box. Maintain correct polarity when wiring the junc-
tion box.
Operation using Battery Power
This appliance has an optional battery operation. The sys-
tem is fully functional with the use of two “D” size batteries
without ordinary 110-120 VAC power.
Wiring to the battery pack should be left disconnected in
order to conserve battery life. In the case of a loss of power,
simply connect red and black wire leads to activate battery
power (connect red to red, black to black). The appliance
can be used as necessary. Once power (110 VAC) is re-
stored, disconnect red and black wire leads to extend bat-
tery life.

Optional Accessories
Optional fan and remote control kits require that 110-120
VAC be wired to the appliance junction box.
Wall Switch
Position the wall switch in the desired position on the wall.
An assembly of 18 ft of 20 AWG is provided with the fire-
place to connect the wall switch to the appliance. Instead of
the supplied assembly, wire with a length of 25 ft or less and
a gauge of 20 AWG through 14 AWG is acceptable. The
wire needs a jacket with a temperature rating of 140

or higher. At the appliance connect the wire to the ON/OFF
switch pigtails.
CAUTION: LABEL ALL WIRES PRIOR TO DISCONNEC-
TION WHEN SERVICING CONTROLS. WIRING ERRORS
