STEP-BY-STEP INSTALLATION

1. Rough in framing opening following the recommended dimensions (Section A: Framing).

2. Allow 8” of service cable for connecting to the junction box on the fireplace. Remove the outer jacket and strip
the individual conductors ½” from the end.

3. Loosen the screw securing 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 opening, level with shims if necessary and attach unit to frame using nailing flanges
provided.

6. Unit is factory wired for 208/240 volt power supply. If 120 volt operation is required, slide the switch and
reconfigure the wiring as covered in section C wiring. Wires L1, L2, N & G are attach ed to the rear of the
junction box cable clamp for easy access.

7. Wire a dedicated, properly fused circuit with a 20amp rating for the appropriate voltage (120, 208/240).

8. Make wall mounted thermostat connections as outlined in Section C: Wiring.

9. Place all connectors inside the unit and replace the junction box cover, ensuring that the cable clamp grips only
the jacket of service or thermostat.

This fireplace is a zero clearance design. Combustibles may be installed to the edge of the unit. A drywall lip at the top
of the unit and four nailing flanges on the sides of the unit are provided on each unit to facilitate installation. Insulation
and vapor barrier can be placed a minimum of 2 inches from the unit.

SECTION B: RECOMMENDED POWER SUPPLY WIRE SPECIFICATIONS

For 120 volt installations use two conductors, non-metallic sheath cable with ground wire for the incoming power supply
on EBU fireplace inserts. Use the appropriate wire to meet local and national electrical code s for rated power
consumption.

For 208 / 240 volt installations use three conductors, non-metallic sheath cable with ground wire for the incoming power
supply on EBU fireplaces. Use the appropriate wire to meet local and national electrical codes for rated power
consumption.

Two conductors, non-metallic sheath cable with ground wire is recommended for installation of a wall mounted
thermostat on EBU fireplaces. Use appropriate wire to meet local and national electrical codes for rated power
consumption. Thermostat switch wire gauge must match the recommended wire sizes shown below.

SECTION C: WIRING

NOTE: The unit is factory configured for 208/240 volt operation
NOTE: All wiring must be completed prior to installing the unit.
NOTE: Ensure that the power conversion switch is in the proper position for the required supply voltage prior to

connecting the unit to power supply.

240 VOLT INSTALLATIONS

1. Locate the switch on the top corner of the unit.

2. Ensure that the switch is in the 230 volt position.

3. Loosen the screw securing the junction box cover and remove the cover.

4. Remove the knockouts (if necessary) or use the provided cable clamp.

5. Pull out the four wires marked L1, L2, N, and G.

6. Connect the black L1 wire from the unit to the L1 from the power supply. Connect the red L2 wire from the unit
to the L2 from the power supply. Connect the white N wire from the unit to the neutral from the power supply.
Connect the green ground wire from the unit to the ground from the power supply.

7. When the unit has been configured for the appropriate power supply voltage, ensure that all connections are
tight. Insert all the wiring into the unit and secure with a cable clamp.

TO RECONFIGURE FROM 240 VOLT TO 120 VOLT

1. Locate the switch on the top corner of the unit.

2. Flip the switch from 230 volt to 115 volt configuration.

3. Loosen the screw securing the junction box cover and remove the cover.

4. Remove the knockouts (if necessary) or use the provided cable clamp.

5. Pull out the four wires marked L1, L2, N, and G.

6. Connect the black L1 wire from the unit to the L1 from the power supply. Connect the red L2 and white N wi res
to the neutral from the power supply. Connect the green ground wire from the unit to the ground from the power
supply.

7. When the unit has been configured for the appropriate power supply voltage, ensure that all connections are
tight. Insert all the wiring into the unit and secure with a cable clamp.
