PRE-INSTALLATION

Before You Start

Check appliance for any concealed damage.

DETAILED INSTALLATION STEPS

1. Complete the framing opening to the dimen-

sions specifi ed 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 fi replace.

- Loosen four screws to remove the junction
box cover plate.

- Disconnect and remove the 120 Volt power
cord from the fi replace wires.

- Position the fi replace into the framed-in
opening. Attach fi replace to frame using
nailing fl anges provided.

- Complete the wiring to the fi replace 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
fi replace.

- Loosen four screws to remove the junction
box cover plate.

- Disconnect and remove the 120 Volt power
cord from the fi replace wires.

- Position the fi replace into the framed-in
opening. Attach fi replace to frame using
nailing fl anges provided.

- Complete the wiring to the fi replace as
shown on Page 11.

- Place all wire connectors inside the junction
box.

- Attach junction box cover plate with four
screws.

The fi replace 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.

4. (If applicable) Make wall mount wall switch
or wall thermostat connections as outlined
on Pages 11 & 12.

5. Perform a function test. See Manual Control

Panel Operation on Page 6 and Remote
Control Operation on Page 7.

ELECTRICAL CONNECTIONS

Refer to the electrical diagrams on Pages 10
to 14.

WARNING

Electrical wiring must comply
with local building codes and
other applicable regulations to
reduce the risk of fi re, electrical
shock and injury to individuals.

IMPORTANT

Any electrical re-wiring of this
appliance must be done by a
qualifi ed electrician.

WARNING

Do not use this fi replace if any
part of it has been underwater.
Immediately call a qualified
service technician to inspect the
fi replace and replace any part of
the electrical system which has
been under water.

FINAL FINISHING

Materials such as brick and tile can be extended
down to the top of the fi replace. Do not extend
down, covering the outlet or glass enclosure
panel (optional kit).

There are a wide variety of “fi nished looks” for
these fi replaces, from formal wall decor with
elaborate mantels to rustic wood paneling or
warm brick facings.

Accent Trim Installations

Note: Ensure the circuit breakers for the power
supply are turned on.

This appliance can be operated either from the
manual control panel (see Figures 4 & 5) or
by using the remote control, wall switch or wall
thermostat (optional kits).

The manual controls are located on the fi rebox
fl oor on the front left (see Figure 5). If an
optional glass enclosure is installed, it must
be removed to access.

Main Power ON/OFF Switch

When the main power switch is turned on, power
is supplied to the fi replace. This switch must be
on for all other switches to operate.

Heater ON/OFF Switch

When this switch is turned on, the heater will
emit heat in the temperature range selected (see
Figure 6; G, H & I). The fi replace can operate
with or without heat.

Flame / Ember On/Off Switch:

Turns lights on inside ember bed and fl ame
cylinder.

An optional accent trim kit is available from your
dealer (see Page 18). These options give the
appliance an attractive fi nished look.

Hearth

An aesthetically pleasing fi replace hearth can
be installed, if desired (see hearth protection
on Page 5).

BREAK-IN PERIOD:

During the fi rst few initial uses of this heater,
there may be a release of a slight, harmless odor.
This odor is a normal occurrence caused by the
initial heating of the internal heating elements
and should not reoccur.
