Section 2: Recommended Power Supply Wire Specifications
For 120 volt installations use two conductor,
non-metallic sheath cable with ground wire
(3 wires total) for the incoming power supply
on fireplace inserts. Use the appropriate wire
to meet local and national electrical codes for
rated power consumption.
Two conductor, non-metallic sheath cable with
ground wire (3 wires total) is recommended
for installation of a wall mounted thermostat
for use on fireplace inserts.
Recommended Wire and
Fusing Requirements
For 208/240 volt installations use three
conductor, non-metallic sheath cable with
ground wire (4 wires total) for the incoming
power supply on fireplace inserts. Use the
appropriate wire to meet local and national
electrical codes for rated power consumption.
Use appropriate wire to meet local and
national electrical codes for rated power con-
sumption. All wire gauges should be
12 gauge with a dedicated 15 amp breaker.

Section 3: Voltage Selector Switch Location
Important:
Caution:
Ensure that the incoming power supply
voltage matches the setting of the
voltage selector switch!!!!!!
When changing the voltage selector switch
from 240 volts to 120 volts ensure that the
power supply is turned off.
The voltage selector switch is located inside
the exhaust panel on the top left hand
corner. Carefully insert a flat headed screw-
driver inside the exhaust panel through the
hole in the mesh to change the switch from
240 volts (230 position) to 120 volts (115
position). The unit ships with the switch in the
115v position.
When wiring the unit for 208/240 volts the
voltage selector switch should be in the 230
volt position. (see figure 2)
When wiring the unit for 120 volts the voltage
selector switch should be in the 115 volt
position. (see figure 2)
