If the appliance is damaged, check with the supplier before installation and operation.
Do not use outdoors.
Do not use in the immediate surroundings of a bath, shower or swimming pool.
Do not locate the heater immediately below a fi xed socket outlet or connection box.
This appliance is not intended for use by children or other persons without assistance
or supervision if their physical, sensory or mental capabilities prevent them from
using it safely. Children should be supervised to ensure that they do not play with the
appliance.
Do not use this heater in series with a thermal control, a program controller, a timer or
any other device that switches on the heat automatically, since a fi re risk exists when
the heater is accidentally covered or displaced.

Unplug the heater when not required for long periods.
Although this heater complies with safety standards, we do not recommend its use on
deep pile carpets or on long hair type of rugs.
The appliance must be positioned so that the plug is accessible.
If the supply cord is damaged it must be replaced by the manufacturer or service agent
or a similarly qualifi ed person in order to avoid a hazard.
Keep the supply cord away from the front of the heater.
WARNING: In order to avoid a hazard due to inadvertent resetting of the thermal cut-
out, this appliance must not be supplied through an external switching device, such
as a timer, or connected to a circuit that is regularly switched on and off by the utility.
WARNING: In order to avoid overheating, do not cover the heater. Do not place material

General.

Unpack the stove carefully and retain the packaging for possible future use, in the event of
moving or returning the stove to your supplier. The stove incorporates a fl ame effect, which can
be used with or without heating, so that the comforting effect may be enjoyed at any time of the
year. Using the fl ame effect on its own only requires little electricity.
These models are designed to be free standing and are normally positioned near a wall.
Before connecting the stove check that the supply voltage is the same as that stated on the
heater.
Please note: 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 fl ame effect. This is normal and should not
be a cause for concern.
If this product experiences a power surge for whateve reason the product may cut-out. This is a
normal safety feature and the product will resume operation after 30 seconds.
Electrical connection.
WARNING – THIS APPLIANCE MUST BE EARTHED.
This stove must be used on an AC ~ supply only and the voltage marked on the heater must
correspond to the supply voltage.
Before switching on, please read the safety warnings and operating instructions.
PLEASE RETAIN THIS USER'S GUIDE FOR FUTURE REFERENCE
Do not put Opti-myst plastic components into a dishwasher.
Only slide out the drawer when the water tank needs to be fi lled or a lamp needs to
be changed otherwise you will inadvertently alter the water level and the fl ame effect
operation.
Only use fi ltered tap water in this appliance.
Always ensure that the appliance is sitting on a level fl oor.
If you intend not using the appliance for longer than 2 weeks, drain the water from sump
and water tank and dry the sump.
Once installed, never move this stove or lay on its back, without draining the water from
sump and water tank.
The water tank, sump, sump lid, tank cap and air fi lters must be cleaned once every two
weeks, particularly in hard water areas.
The appliance should never be operated if the lamps are not working.
The lamps should be regularly inspected as described under 'Maintenance' and
'Changing lamps'.
Installation Instructions
Ensure that all packing items are removed (read any warning labels carefully).
Retain all packing for possible future use, in the event of moving or returning the
appliance to your supplier.
To reduce heat losses and to prevent any chimney updraught affecting the operation
of your fi re we recommend that the chimney fl ue is blocked off, ensuring that there is a
slight gap for ventilation.

To install the appliance;

Place the stove against a wall and connect the stove to your electricity supply.
Plug the stove into a 13amp/240volt outlet.
Before switching on the appliance, please read the following instructions.
Before using the product fi rstly fi ll the water tank (See 'Maintenance', 'Filling the water
tank').

Manual Controls.

The stove Manual controls are located behind the doors.
(See Fig.2 for Manual Control lay out)
Switch 'A':- Controls the electricity supply to the heater.
Note: This switch must be in the 'ON' (
heat. This will be indicated by one beep. Although the main lights operate immediately it will take
a further 30 seconds before the fl ame and smoke effect starts.
Switch 'B':- Press 1kw to turn on half heat.
Switch 'D':- Press 2kw to turn on full heat.
Control Knob 'C':- Controls the intensity of the fl ame and smoke effect.
Turnng the control knob to the left increases the fl ame effect, turning the control knob to the right
will decrease the fl ame effect.
When the water tank is empty the main lamps go out. See instructions under 'Maintenance',
'Filling the water tank'. When this procedure is complete, the main lamps will illuminate but it will
take 30 seconds before the fl ames return.
Depending on room temperature and humidity upon initial start up there may be some
condensation on the inside of the stove. This can be overcome by turning the fl ame
control knob down and leaving the doors of the stove slightly ajar, until the glass warms
up.
Thermal safety cut-out
A thermal safety cut-out is incorporated in the fan heater to prevent damage due to overheating.
This can happen if the heat outlet was restricted in any way. If the cut-out operates, unplug the
heater from the socket outlet and allow approximately 10 minutes before reconnecting. Before
switching the heater back on remove any obstruction that may be restricting the heat outlet, then
continue normal operation.
Tips for using your appliance.
1. Only pull out the drawer when it's time to refi ll the water tank or change a lamp, otherwise it
may lead to excess water in the sump and reduced fl ame effect. If this happens empty the water
from the sump as instructed under 'Maintenance'.
2. With the fl ame setting on minimum the unit will use approximately 40ml of water per hour and
will last 3 times as long than when it is at maximum fl ame setting.
3. Do not tilt or move the stove while there is water in the tank or sump.
4. Make sure that the stove is on a level fl oor.
5. The fl ame control knob 'C' Fig.2 may be turned up or down to give a more realistic effect. Do
not assume that the setting should be on maximum because sometimes the fl ames and smoke
effect appear more real when the fl ame control knob is turned down.
6. Give the fl ame and smoke generator some time to react to changes you may make on the
fl ame control knob.
7. If condensation occurs on the inside surfaces, reduce the amount of smoke and fl ames
produced and leave the doors slightly ajar.
Maintenance

ANY MAINTENANCE
Fitment and replacing lamps.
If a large amount of the smoke appears grey or colourless it may be that one or more lamps
have failed.
You can check for lamp failure as follows.
1. Leaving the fl ame effect on, open the door fully and gently pull the drawer fully out. (See
Fig.3)
2. View the lamps from a distance in front of the stove and observe which lamp needs to be
changed.
3. Put Switch 'A' in the 'OFF' (0) position, and unplug the stove from the mains.
4. Leave the appliance for 20 minutes to allow the lamps to cool down before removing them.
5. Remove the water tank by lifting upwards and place in a sink.
6. Remove the sump as described in the Cleaning Section.
7. Remove the defective lamp, by gently lifting vertically and disengaging the pins from the
lamp holder, (See Fig.4 and 5). Replace with a Dimplex Opti-myst, 12V, 50W, Gu5.3 base, 8º
beam angle, coloured lamp. (Purchased from www.dimplex.co.uk under the section 'After Sales
Service', details of how to purchase the lamps are contained therein.)
