Operation
Electric Fireplace Manual Control
The manual controls for the unit are located behind the
control panel on the front of the rebox (Figure 1). A switch
is in the ON position when the side with the markings on it
(i.e. I, or II) is pushed in.
A - 3 Position On/Off Switch
(I) Manual mode
Controls the electricity supply to the heater and ame
manually.
(II) Remote mode
Allows the control of electricity supply to the heater and ame
through the use of the supplied remote control.
!NOTE: This switch must be in the ON (I) position for
heater to operate with or without heat.
B - Low Heat Switch
(I) Provides 715 Watt heat output.
C - High Heat Switch
(II) Provides 1430 Watt heat output with Switch B.
!NOTE: If Switches B and C are in the off position, only
the ame effect will turn on when Switch A is activated.
Remote Control
The replace is supplied with an integral on/off remote
control.
!NOTE: Ensure that the replace’s 3 Position On/Off
Switch is set to the remote control setting (I.E.. II).
To operate: push ON button to turn replace on; push OFF
button to turn replace off (Figure 2).
!NOTE: Remote control operates main power supply. Heat
must still be controlled by switches on replace.
Battery Installation/Replacement

remote transmitter and remove battery cover (Figure 2).
2. Properly orientate and install one (1) 12 Volt (A23) battery
into the remote control.
3. Replace the battery cover.
Resetting The Temperature Cutoff Switch
Should the replace 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 Switch A (Figure 1 A) to
OFF and waiting ve (5) minutes before switching the unit
back on.
CAUTION: If you need to continuously reset the heater,

Light Bulb Replacement
Allow at least ve (5) minutes for light bulbs to cool before
touching bulbs to avoid accidental burning of skin.
Light bulbs need to be replaced when you notice a dark
section of the ame. There are two (2) bulbs behind the log
set which generate the ames and embers.
Disconnect power before attempting any maintenance or
cleaning to reduce the risk of electric shock or damage to
persons.
Helpful Hints
It is a good idea to replace all light bulbs at one time if they
are close to the end of their rated life. Group replacement
will reduce the number of times you need to open the unit to
replace light bulbs.
Lower Light Bulb Requirements
Quantity of two (2) clear chandelier or candelabra bulbs with
an E-12 (small) socket base, 60 Watt rating.
Do not exceed 60 Watts per bulb
To access the light bulb area (Figure 3):
1. Remove the one (1) silver Phillips screw on the Access
Panel at the rear of the rebox and remove panel.
2. Examine the bulbs to determine which bulbs require
replacement.
3. Hold the socket while unscrewing the bulb.
4. Hold the socket while screwing in the new bulb.
5. Reattach Access Panel with the screw removed in step 1.
!NOTE: The top tab of the Access Panel will tuck inside
the rebox and the metal plate attached to the Access
Panel will slide in, over the top of the light bulbs.
Mirror Replacement
If the replace was operating prior to servicing allow at least
ve (5) minutes for light bulbs and heating element to cool off
to avoid accidental burning of skin.
Disconnect power before attempting any maintenance or
cleaning to reduce the risk of electric shock or damage to
persons.

1. Pull replace away from the wall far enough to access
the back of the unit.
2. Remove one (1) Phillips screw from each of the two (2)
brackets which attach the upper part of the rebox to the
mantel, and remove the three (3) Phillips screws along
the bottom edge (Figure 4).
