Important Safety Advice:
When using electrical appliances, basic
precautions should always be followed to reduce
the risk of fire, electrical shock and injury to
persons, including the following:
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 stove immediately below a fixed
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 stove in series with a thermal
control, a program controller, a timer or any other
device that switches on the heat automatically,
since a fire risk exists when the stove is
accidentally covered or displaced.
Ensure that furniture, curtains or other
combustible material are positioned no closer than
1 metre from the stove.
In the event of a fault unplug the stove.
Unplug the stove when not required for long
Although this stove 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
qualified person in order to avoid a hazard.
Keep the supply cord away from the front of the
WARNING: In order to avoid overheating, do not
cover the stove. Do not place material or garments
on the stove, or obstruct the air circulation around
the stove.
The stove carries the Warning symbol
indicating that it must not be covered.
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 Remote Control and
batteries are packed separately in the carton.
The stove incorporates a flame 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 flame effect
on its own only requires little electricity.
These models are designed to be free standing and are
normal positioned near a wall.
Before connecting the stove check that the supply voltage
is the same as that stated on the stove.
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 flame effect. This is
normal and should not be a cause for concern.
Electrical connection.
This stove must be used on an AC ~ supply only and the
voltage marked on the stove must correspond to the
supply voltage.
Before switching on, please read the safety warnings and
operating instructions.
Do not put Opti-myst plastic components into a
Only slide out the drawer when the water tank needs
to be filled or a lamp needs to be changed otherwise
you will inadvertently alter the water level and the
flame effect operation.
Only use filtered tap water in this appliance.
Always ensure that the stove is sitting on a level floor.
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
The water tank, sump, sump lid, tank cap and air filters
must be cleaned once every two weeks, particularly in
hard water areas.
The stove 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 sffecting the operation of your fire we
recommend that the chimney flue is blocked off,
ensure that there is a slight gap for ventilation.
To install the appliance;
Place the stove against the wall and connect the stove to
your electricity supply.
Plug the stove into a 13amp/24volt outlet.
Before switching on the appliance, please read the
following instructions.
Before using the manual controls firstly fill the water
tank (See ‘Maintenance’, ‘Filling the water tank’).
Manual Controls.
The Opti-myst Manual controls are located behind the
(See Fig.2 for Manual Control lay out)
Switch ‘A’:- Controls the electricity supply to the stove.
Note: This switch must be in the ‘ON’ ( I ) position for the
stove to operate with or without heat.
Switch ‘B’:- Controls the function of the fire.
Press once to turn on flame effect. This will be
indicated by one beep.
Although the main lights operate immediately it will
take a further 30 seconds before the flame effect
Press again to give flame effect and half heat.
This will be indicated by two beeps.
Press again to give flame effect and full heat.
This will be indicated by three beeps.
Press again to return to flame effect only.
This will be indicated by one beep.
Press to put stove in to standby mode.
This will be indicated by one beep.
Control Knob ‘C’:- Controls the intensity of the flame
Turning the control knob to the left increases the
flame effect, turning the control knob to the right
will decrease the flame effect.
Control Knob ‘D’:- Controls the Electronic Thermostat
Turning the control knob to the left will decrease
the temperature setting, turning the control knob to
the right will increase the temperature setting.
When the water 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 flames
Depending on room temperature and humidity there may
be some condensation on the inside of the stove. This can
be overcome by turning the flame control knob down and
leaving the doors of the stove slightly ajar, until the glass
warms up.
Electronic Thermostat
The thermostat controls the heat output according to the
room temperature. This ensures that the stove will not
produce heat unnecessarily when the room is warm.
To set the temperature you require, turn the thermostat
control knob ‘D’ (See Fig.2) to the right until the desired
temperature is reached. Alternatively to heat a cold room
quickly, turn the thermostat control knob ‘D’ (See fig.2) up
fully. When the room has reached the desired temperature,
turn the thermostat control knob ‘D’ (See Fig.2) to the left
until the desired heat setting is achieved.
The stove will now automatically operate at this
Remote Control Operation
On the control panel, Switch A (see Fig.2) must be in the
‘ON’ ( I ) position in order for the remote control to operate. There are 3 buttons on the remote control. (See Fig.7)

Any battery may leak electrolyte if mixed with a different
battery type, if inserted incorrectly, if all the batteries are
not replaced at the same time, if disposed of in a fire, or if
an attempt is made to charge a battery not intended to be
Thermal safety cut-out
A thermal safety cut-out is incorporated in the fan stove
to prevent damage due to overheating. This can happen if
the heat outlet was restricted in any way or if the chimney
flue has not been blocked off effectively. If the cut-out
operates, unplug the stove from the socket outlet and
allow approximately 10 minutes before reconnecting.
Before switching the stove 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 its time to refill the
water tank or change a lamp, otherwise it may lead to
excess water in the sump and reduced flame effect. If this
happens empty the water from the sump as instructed
under ‘Maintenance’.
2. With the flame 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 flame 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 floor.
5. The flame control knob ‘C’ Fig.2 may be turned up or
down to give a more realistic effect.
6. Sometimes the flames appear more real when the flame
control knob is turned down.
7. Give the flame generator some time to react to
changes you may make on the flame control knob.
Changing 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 flame effect on, open the doors fully, gently
pull the drawer fully out by the tab. (See Fig.3)
2. View the lamps from a distance in front of the stove and
observe which lamp needs to be changed.
