OPERATION
MANUAL CONTROLS
(WITHOUT REMOTE OPTION)
The fireplace can be controlled by the manual
switches located on the fireplace (FIGURE 1).
Main Power Switch
Main ON/OFF switch, activates the flame effect.
Heater Control Switch
Heater ON/OFF switch, activates heater to the high
level.
MANUAL CONTROLS
(WITH REMOTE OPTION)
The fireplace can also be controlled in a similar
manner to the remote control with the manual
switches located on the fireplace (FIGURE 2).
(refer to initialization instructions on page 2)
Main Power Switch
Main ON/OFF switch supplies power to the circuit
board. When the Main ON/OFF switch is switched to
the ON position the Level 1 indicator light will flash.
On Switch
1. Pressing once on the remote control board “ON
SWITCH” activates the Level 1 function.
Level 1: The flame effect is turned on and the first
red indicator light is activated.
2. Pressing twice on the remote control board “ON
SWITCH” activates the Level 2 function.
Level 2: The flame effect remains on, the heater
is activated to the low heat setting, and
the first and second red indicator lights are
activated.
3. Pressing three times on the remote control board
“ON SWITCH” activates the Level 3 function.
Level 3: The flame effect remains on, the heater
is set to the high heat setting, and all three red
indicator lights are activated.
Off Switch
Pressing this button ONCE will turn the unit OFF.

REMOTE CONTROL
The remote control has a range of approximately 50ft. (15.25m). It
does not have to be pointed at the fireplace and can pass through
most obstacles (including walls). It is supplied with one of 243
independent frequencies to prevent interference with other units.
The frequency designation is indicated on the back of the
transmitter (FIGURE 3).
Remote Control Initialization
This procedure is required every time there is a loss of power to the
remote control in the fireplace (i.e. power failure, breaker tripped,
main power switch is turned off)
1. Ensure that power is supplied through main service panel.
2. Access the manual controls, (remove glass doors if applicable)
pull the right hand steel curtain to the side of the unit.
(FIGURE 4)
3. Locate manual controls refer to FIGURE 5.
4. Activate main power switch, (“ ” position is “ON”, “ ” position
is “OFF”) red Level 1 indicator light will flash.
5. Press and hold the ON switch marked “ ” for five seconds.
The red Level 2 indicator light will flash.
6. Press the ON button located on the remote control transmitter
(FIGURE 3). This will synchronize the remote control
transmitter and receiver.
Remote Control Usage
The remote control operates the fireplace levels sequentially. The level is increased
every time the ON button on the transmitter is pressed. The fireplace can be turned off
at any point by pressing the OFF button on the remote control transmitter.
Level 1: The flame effect is turned on and the first red indicator light is activated.
Level 2: The flame effect remains on, the heater is activated to the low heat setting,
and the first and second red indicator lights are activated.
Level 3: The flame effect remains on, the heater is set to the high heat setting, and all
three red indicator lights are activated.

RESETTING THE TEMPERTURE CUTOUT SWITCH
The heater on this fireplace is protected with a safety device to prevent overheating.
Should the heater overheat, an automatic cut out will turn the heater off and it will not
come back on without being reset. It can be reset by switching the Main Power switch
(FIGURE 1) to OFF and waiting 5 minutes before switching it to ON.
WALL MOUNTED CONTROLS
The fireplace can be installed with wall mounted controls. These controls include wall
switches and thermostats. (see installation guide for details)
A. Wall Mounted Switches
This model may be installed such that a wall mounted switch activates the flame effect
and a wall mounted heater switch activates the heater. A wall mounted switch can also
be installed to operate the heater independent of the flame.
B. Wall Mounted Thermostat
This unit may be installed such that a wall mounted thermostat can adjust the heat
temperature to your individual requirements. Turn the thermostat control clockwise all
the way to turn on the heater. When the room reaches the desired temperature, turn
the thermostat knob counter clockwise until you hear a click. Leave in this position to
maintain the room temperature at this setting. For additional heat, turn the thermostat
clockwise until you hear the click again and the heater will turn on. To turn the heater
off, turn the thermostat counter clockwise all the way, and/or turn the manual heater
switch on the unit to the OFF position.
VOLTAGE SELECTOR SWITCH LOCATION
IMPORTANT:
Ensure that the incoming power supply voltage
matches the setting of the voltage selector
switch.
NOTE:
The voltage selector switch is located
inside the exhaust panel on the top
right hand corner (FIGURE 6).
CAUTION:
When changing the voltage selector
switch from 240 volts to 120 volts
ensure that the power supply is turned
off.
NOTE:
Carefully insert a flat headed screwdriver inside the exhaust panel to change the switch
from 240 volts (230 position) to 120 volts (115 position).
