INSTALLATION

STEP-BY-STEP INSTALLATION

NOTE: Please read all instructions before installing.

Rough in framing opening following the recommended dimensions located in Section A: Framing Dimensions.
Allow 8″ (20.3 cm) of service cable for connecting power supply wire to junction box on fireplace when installing before finishing wall. Allow up to 4′ (121.9 cm) 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” (1.3 cm) from the end.
Loosen the screw securing the junction box cover and remove the cover.
Remove knockouts, if necessary, or use the provided cable clamp.
Place unit in position in the framed opening, level with shims if necessary and attach unit to frame using mounting flanges provided (Figure 3).
Unit is factory wired for 208/240V power supply. If 120V operation is required, slide the switch and reconfigure the wiring (Section C). 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.
Wire a dedicated, properly fused circuit with a 15amp rating for the appro-priate voltage (120V, 208/240V). See Section C for factory setting wiring.
Make wall switch and or wall mounted thermostat connections as outlined in Section D.
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.

SECTION A: INSTALLATION INFORMATION FRAMING DIMENSIONS

No combustibles can be placed on the top surface of the fireplace. Combustibles may be installed to the front 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″ (5.1 cm) from the unit.
CAUTION : Ensure installation does not allow fireplace to be in direct contact with building vapor barrier or insulation and meets all local building code.

TRIM MOUNTING

This fireplace comes with three trim pieces, top and two sides. The top piece is secured with screws at either end and one in the middle. The two side pieces require a tab to be inserted in the center slot then secured with a screw at the top and bottom.

MOUNTING FLANGES

NOTE: The trim should be installed before securing the firebox in the opening. There are two mounting flanges located on each side of the fireplace insert. From the inside of the unit, bend tabs outward and mount to the inside of the framing using suitable hardware.

SECTION B: GENERAL ELECTRICAL INFORMATION

RECOMMENDED POWER SUPPLY WIRE SPECIFICATIONS

For 120V 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 208V / 240V 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.
