! NOTE: When the engine is used in an environment
where background noise is very low, it may be possible to
hear a sound which is related to the operation of the flame
effect. This is normal and should not be a cause for concern.
! NOTE: Always ensure that the appliance is fixed to the
wall in a level position.
The manual controls for the wall mount engine are located
on the bottom of the unit. (Figure 1)
A. On/Off Switch
Supplies power to the engine.
B. Thermostat Control
To adjust the temperature to your individual requirements,
turn the thermostat control backwards all the way to turn on
the heater. When the room reaches the desired temperature, turn the thermostat knob forward until you hear a click.
Leave thermostat in this position to maintain the room temperature at this setting. For additional heat, turn clockwise
until you hear the click again and the heater will turn on.
C. Mode Selector Switch
Press once to turn on the flame effect. This will be indicated
by an audible “beep”. Although the lights turn on immediately it will take 30 seconds before the flame effect starts.
• Press again to give flame effect and full heat. This will
be indicated by two “beeps”.
• Press again to return to flame effect only. This will be
indicated by one “beep”.
• Press
to put fire in to standby mode. This will be
indicated by one “beep”.
D. Flame Intensity Control
Adjusts the intensity of the flame and smoke effect when the
heater has been activated.
Turning the control knob towards you decreases the intensity of the flame and smoke effect. Turning the control knob
away from you will increase the flame and smoke effect.
! NOTE: Give the flame generator some time to react to
changes you may make on the flame control knob.
! NOTE: When the water tank is empty the unit will turn
off after 30 seconds. See instructions under Maintenance
Section for refilling tank. When this procedure is complete,
the main lamps will illuminate but it will take 30 seconds
before the flames return.
Should the heater overheat, an automatic cut out will turn
the fireplace off and it will not come back on without being
reset. It can be reset by switching the On/ Off Switch to Off
and waiting ten (10) minutes before switching the unit back
on.
CAUTION: If you need to continuously reset the heater,
unplug the unit and call Dimplex North America Limited at
1-888-346-7539 for technical support. Please have your
model and serial number ready when calling.
Remote Control
The On/Off Switch must be in the ‘ON’ ( I ) position in order
for the remote control to operate. There are 3 buttons on
the remote control. (Figure 2)
! NOTE: To operate correctly the remote control must be
pointed towards the heater outlet.
The remote control functions are as follows:
Press once to turn on Flame effect only. This will be
indicated by one beep.
Press once to turn on Full heat and Flame effect. This
will be indicated by two beeps.
Standby - This will be indicated by one beep.
! NOTE: Once the mist has been activated, the unit will
have to be turned Off, using either the momentary button,
on the unit, or the Off button on the remote control, then
back on to return to Level 1 - Logs and Light only operation.
Battery Replacement

water or distilled water with 1/8 tsp of salt (0.5 mL) added to
the water reservoir. (The addition of additional salt should
only be when you notice that the unit is not producing mist
as expected.)
5. Screw the cap back on, do not overtighten.
6. Return the refill container to the sump, with the tank
cap facing down and the flat side of the tank facing
outward.
7. Gently place the media tray and rock media back into
