D. Flame Intensity Control
Adjusts the intensity of the ame and smoke effect when the
heater has been activated.
Turning the control knob clockwise decreases the intensity
of the ame and smoke effect. Turning the control counter-
clockwise will increase the ame and smoke effect.
!NOTE: Give the ame generator some time to react to
changes you may make on the ame control knob.
!NOTE: When the water tank is empty the unit will turn
off after 30 seconds. See instructions under Maintenance
Section for relling tank. When this procedure is complete,
the main lamps will illuminate but it will take 30 seconds
before the ames return.
Resetting the Temperature Cutoff Switch
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 On/ Off Switch to Off
and waiting 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 (Figure 5A). There are 3
buttons on the remote control. (Figure 2)
!NOTE: To operate correctly the remote control must be
pointed towards the remote control sensor.
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

OPERATION
Figure 1
WARNING: This electric rebox must be properly in-
stalled before it is used.
!NOTE: When the unit 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 ame effect.
This is normal and should not be a cause for concern.
!NOTE: Always ensure that the appliance is in a level
position.
The manual controls for the unit are located below the con-
trol cover in front of the log grate (Figure 1).

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 ame effect. This will be
indicated by an audible “beep”. Although the lights turn on
immediately it will take 30 seconds before the ame effect
starts.

MAINTENANCE
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of re, elec-
tric shock or damage to persons.
Filling the water tank
When the water tank is empty, the ame effect shuts off
and you will hear 2 audible beeps, follow these steps.
CAUTION: Allow at least ve minutes for components to
cool before disassembling the unit to rell.
1. Turn the On/Off switch to the off position (0) (Figure 1)
2. Gently remove the log set and place it carefully on the
ground.
3. Remove the rell container by lifting upwards and
outwards.
4. Rell the container with tap water.
!NOTE: Normal tap water can be used in the Opti-
myst®as long as the tap water is not considered to be
hard water. In the event your tap water is hard, you may
use softened 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 rell container to the sump, with the tank
cap facing down and the at side of the tank facing
outward.
7. Gently place the log set back into position.
8. Turn the On/Off switch to the off position (I). (Figure
1)
If you do not intend on using the unit for longer than 2
weeks, empty and drain the unit of water, and dry all of
the water containing components.
Replacing the Light bulbs
If a large amount of the smoke appears grey or colourless it
may be that one or more of the light bulbs have burnt out.
CAUTION: Allow at least twenty minutes for light bulbs
to cool before touching bulbs to avoid accidental burning of
skin.
1. Leaving the ame effect on, remove the log set and wa-
ter tank and lift out the top cover (Figure 3).
2. View the lamps from a distance in front of the re and
observe which lamp needs to be changed.
3. Turn the unit off, and unplug the unit.
4. Leave the appliance for 20 minutes to allow the lamps
to cool down before removing them.
5. Remove the defective bulb, by gently lifting vertically
and disengaging the pins from the lamp holder.
!NOTE: Replacement light bulbs can be obtained by
contacting Dimplex Customer Service at 1-888-346-7539.
6. Carefully insert the two pins of the new bulb into the
two holes in the lamp holder. Push lamp rmly in place.
7. Replace the top cover, rell container and log set.
Cleaning
It is recommended that all of the components that contain
water are cleaned with soap and water on a biweekly ba-
sis. A small brush has been included to assist in cleaning
difcult items/areas, i.e. the transducer.
CAUTION: Do not put plastic components in the dish-
washer.
