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 Dimensions.

2. Allow 8″ (20.3 cm) of service cable for connecting power supply wire to a junction box on the fireplace when installing before finishing the wall. Allow up to 4′ (121.9 cm) of service cable for connecting power supply wire to a junction box on the fireplace when installing after finishing wall. Remove the outer jacket and strip the individual conductors ‘A” (1.3 cm) 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 (Figure 2).

6. 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.

7. Wire a dedicated, properly fused circuit with a 15amp rating for the appropriate voltage (120V, 208/240V). See Section C for factory setting wiring.

8. Make wall switch and or wall-mounted thermostat connections as outlined in Section D.

9. Place all connectors inside the unit and secure the junction box cover to the unit. Ensure that the cable clamp grips only the jacket of service cable, thermostat and if applicable wall switch lines.

WARNING: Ensure the method of installation does NOT obscure the air intake slots on the bottom front of the unit in any manner. (See diagram in Section A).
