WARNING
The installation of the fireplace unit must comply with the applicable Local and/or National
Electrical Codes and utility requirements. This installation should be entrusted to duly qualified
personnel where required by law.
STEP-BY-STEP INSTALLATION(Note: Please read all instructions before installing)
1. Rough in framing opening following the recommended dimensions located in
(Section A: Framing).
2. Allow 8” of service cable for connecting power supply wire to junction box on fireplace
when installing before finishing wall. Allow up to 4 feet of service cable for connecting
power supply wire to junction box on fireplace when installing after finishing wall.
Remove the outer jacket and strip the individual conductors ½” from the end.
3. Loosen the screw securing the junction box cover and remove the cover.
4. Remove knockouts if necessary or use the provided cable clamp.
5. Place unit in position in the framed opening, level with shims if necessary and attach
unit to frame using mounting flanges provided (see figure 3 on page 3).
6. Unit is factory wired for 208/240 volt power supply (see figure 1 on page 3). If 120 volt
operation is required, slide the switch and reconfigure the wiring
(see figure 2 on page 3). Wires L1, L2, N & G are attached to the rear of the junction
box cable clamp for easy access.
Note
If wiring unit to operate with NO heat a dedicated circuit may not be required.
7. Wire a dedicated, properly fused circuit with a 15amp rating for the appropriate voltage
(120, 208/240). (see Section C for factory setting wiring)
8. Make wall switch and or wall mounted thermostat connections as outlined in Section D:
Wiring.
9. Place all connectors inside the unit and secure the junction box cover to unit. Ensure
that the cable clamp grips only the jacket of service cable, thermostat and if applicable
wall switch lines.

WARNING
Ensure method of installation does NOT obscure the air intake slots on bottom front of unit
in any manner. (see diagram in Section A)
SECTION A: FRAMING Dimensions
This fireplace is a zero clearance design. No combustibles can be placed on the top surface of the fireplace.
Combustibles may be installed to the edge of the unit. Four mounting flanges on the sides of the unit are provided
to facilitate installation. Insulation and vapor barrier should be placed a minimum of 2 inches from the unit.
SECTION B: 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.
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.
Two conductor, non-metallic sheath cable with ground wire (3 wires total) is recommended for
installation of a wall mounted thermostat and/or wall switch for use on fireplace inserts. Use
appropriate wire to meet local and national electrical codes for rated power consumption. All
wire gauges should match the recommended wire sizes shown below.

voltage matches the setting of the voltage
selector switch.
NOTE:
The voltage selector switch is located
inside the exhaust panel on the top
right hand corner.
CAUTION:
When changing the voltage selector
switch from 240 volts to 120 volts
ensure that the power supply is turned
off.
NOTE:
Carefully insert a flat headed
screwdriver inside the exhaust panel
to change the switch from 240 volts
(230 position) to 120 volts (115 position).
When wiring the unit for 208 / 240 volts
the voltage selector switch should be
in the 230 volt position. (see figure 1)
When wiring the unit for 120 volts
the voltage selector switch should be
in the 115 volt position. (see figure 2)
MOUNTING FLANGES
There are two mounting flanges located
on each side of the fireplace insert.
Bend tabs and mount to framing using
suitable hardware.
