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.

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
