DETAILED INSTALLATION STEPS
1. Complete the framing opening to the dimen-
sions specified in Figure 2.
2. Ensure that there is a minimum of 8" of
service cable for connection to the junction
boxon the fireplace. Remove theouter jacket
and strip the individual wires 1/2" from the
end.
3. Loosen the screw securing the junction box
cover and remove the cover.
4. Position the fireplace into the framed-in
opening. Attach fireplace to frame using
nailing flanges provided.
5. Complete the wiring to the fireplace for the
appropriate voltage (120 V or 240 V), as
shown on Pages 10 & 11. Wires L1, L2, N
& G are attached to the rear of the junction
box cable clamp for easy access.
Table 2
ELECTRICAL CONNECTIONS
Refer to the electrical diagrams on Pages 10
to 14.
This appliance is an electric fireplace designed
to be framed in with combustible materials (up
to the edge of the appliance). A drywall lip at
the top of the fireplace and 4 nailing flanges
on the sides of the appliance is provided to
facilitate installation.
6. 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 over-
loading 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.
7. (If applicable) Make wall mount wall switch
or wall thermostat connections as outlined
on Pages 11 & 12.
8. Place all connectors inside the fireplace and
replace the junction box cover, ensuring
that the cable clamp grips only the jacket
of service, and if applicable, wall switch or
thermostat lines.
9. Perform a function test. See Manual Control
Panel Operation on Page 6 and Remote
Control Operation on Page 7.
Hearth Protection: A hearth is not mandatory,
but it is recommended for aesthetic purposes.
Secure the hearth extension to the floor to
prevent possible shifting. Do no block the air-
flow beneath the appliance (read the following
WARNING).
WARNING

ging or loose insulation, the
appliance must not be installed
againstvaporbarriersorexposed
insulation. Localized overheat-
ing could occur and a fire coudld

barrier should be placed a
minimum of 2 inches from the
appliance.
WARNING
This appliance is mounted on
rubber feet to ensure adequate
aircirculation beneathfireplace.
Donot block airflow at the bottom
air intakes.
IMPORTANT
Cold climate installation recom-
mendation: when installing this
fireplace againsta non-insulated
exterior wall or chase, it is
mandatory that the outer walls
be insulated to conform to appli-
cable insulation codes.
WARNING
Electrical wiring must comply
with local building codes and
other applicable regulations to
reduce the risk of fire, electrical
shock and injury to individuals.
IMPORTANT
Any electrical re-wiring of this
appliance must be done by a
qualified electrician.
WARNING
Do not use this fireplace if any
part of it has been underwater.
Immediately call a qualified
service technician to inspect the
fireplace and replace any part of
the electrical system which has
been under water.

TROUBLESHOOTING
SYMPTOM POSSIBLE
CAUSES
WHO PERFORMS
CORRECTIVE ACTION
CORRECTIVE ACTION
1. Fireplace turns off and
will not turn on.
Fireplace has
overheated.
Homeowner The appliance is protected with a
safety device to prevent it from
overheating. If the fireplace should
overheat, a thermal switch will
disconnect power to the unit and
will not come back on without
being reset. Reset it by turning
the main power switch off and
waiting 5 minutes then turning it
back on.
2. Flame is fixed
(unmoving).
Wiring may be loose
or the flame motor
may be defective.
Qualified Service Technician Inspect all wiring for loose
connections. If the wire
connections are good, replace the
flame motor.
3. Dim or poorly visible
flame or log set and
ember is not glowing.
Light bulb(s) burnt out
or wiring is loose.
Homeowner Inspect all wiring for loose
connections and repair or replace
if necessary. Inspect light bulbs
and replace if necessary.
4. Flame sputters. Flame motor is
defective.
Qualified Service Technician Replace flame motor.
5. Remote control does not
work.
Low batteries.
Unit switch and/or
wall switch in “ON”
position.
Homeowner Replace AA batteries in remote
control. If problem persists, there
may have been a loss of power to
the unit as a possible result from a
power failure (i.e. breaker tripped).
Turn off main power on/off switch
(see Figure 4) and/or optional wall
switch (if applicable).
6. Circuit breaker trips or
fuse blows when the unit
is turned on.
Improper circuit
current rating.
Qualified Service Technician Check the house circuit to ensure
it is on a dedicated circuit with
proper Amp. rating. If the circuit
breaker continues to trip (or blown
fuses), inspect wiring for a loose
connection or a dead short. Repair
or replace wiring and/or
connectors as necessary.
