PRE-INSTALLATION
Before You Start
Check appliance for any concealed damage.
DETAILED INSTALLATION STEPS
1. Complete the framing opening to the dimen-
sions specified in Figure 2.
2. Prepare the connections to power source:
120 Volt Connections - Locate the power
cord on the left side of the unit and connect
it to the outlet installed during the framing
(see Figure 2). Verify that the power to the
receptacle is off.
Hard wired installation:
Ensure that there is a minimum of 8" of the
service cable for connection to the junction
box on the fireplace.
- Loosen four screws to remove the junction
box cover plate.
- Disconnect and remove the 120 Volt power
cord from the fireplace wires.
- Position the fireplace into the framed-in
opening. Attach fireplace to frame using
nailing flanges provided.
- Complete the wiring to the fireplace as
shown on Page 10.
- Place all wire connectors inside the junction
box.
- Attach junction box cover plate with four
screws.
240 Volt Connections - Ensure that there
is a minimum of 8" of the service cable
for connection to the junction box on the
fireplace.
- Loosen four screws to remove the junction
box cover plate.
- Disconnect and remove the 120 Volt power
cord from the fireplace wires.
- Position the fireplace into the framed-in
opening. Attach fireplace to frame using
nailing flanges provided.
- Complete the wiring to the fireplace as
shown on Page 11.
- Place all wire connectors inside the junction
box.
- Attach junction box cover plate with four
screws.
The fireplace wires L1, L2, N, N1, N2 and
G are attached to the rear of the junction
box cable clamp for easy access.
3. Wire a dedicated, properly fused circuit with
an Amp rating for the appropriate voltage
(120 V - 15 Amps or 240 V - 20 Amps).
A dedicated circuit is required to prevent
overloading a house circuit in cases of having
multiple appliances on the same circuit.
Use an outlet that is protected by a ground
fault circuit interrupter where required by
electrical code.
(If applicable) Make wall mount wall switch
4.
or wall thermostat connections as outlined
on Pages 11 & 12.
5. Perform a function test. See Manual Control
Panel Operation
Control Operation
on Page 6 and Remote
on Page 7.
