MAINTAINING YOUR OPTIMYST FIRE
Maintaining your
Optimyst Fire
Carry out some simple, regular maintenance on your
Optimyst fire by cleaning the transducer and water
bottle with warm water.
Use filtered water wherever possible – lime scale in hard
water areas will stop the transducer working.
Only use the water tank provided to refill the sump unit.
Remind the customer to register for their additional
warranty at dimplex.co.uk/register.
Don’t allow the water to stand, unused in the fire for
more than two weeks.
Don’t use de-ionised water
FAQs
How often must I refill the water in an Optimyst fire?
Optimyst fires can operate for 8-10 hours on a single fill of water.
Will an Optimyst add to the humidity of the room?
Not significantly – it is the equivalent of having someone else with
you in the same room breathing normally.
What is the power consumption of an Optimyst fire when using
the flame eect only?
Optimyst fire uses 200 watts when operating in flame only mode.
How often should I clean an Optimyst fire?
Cleaning every 2 weeks will help ensure smooth running.
Troubleshooter
The Stove door is misting up.
Sometimes on start up the stove door can mist up. This will
stop when the temperature of the stove rises. You can resolve
this by opening the stove door slightly and turning the flame
eect down.
The light comes on but there is no flame eect?
Check that the transducer is sat correctly in the sump unit
and the wires are connected. If they are and your flame
eect doesn’t work, you will require a new transducer.
The flame eect is beginning to look dull?
Check that all of the lamps are illuminated and clean. If any
lamps are o, check that they are fitted properly. If they
remain o, they will need to be replaced. For replacement
bulbs, please contact Dimplex.
No Heat: (No heat from electric fire).
Your thermostat may be set too high - therefore the electric
fire thinks the room temperature is adequate and that no
heat is needed.
Depending on the model you have:-
Turn the electric fire ON by pressing the on/standby button.
Press the M (Mode Button) until the display reads °C
- this is the thermostat setting.
Using the + button increase the temperature to its highest setting.
Now, using the Mode button select the HEAT setting
and press the + button to turn the heater on.
Turn thermostat control knob to the right to increase the
temperature setting

1. Switch the fire o on the unit and at the mains.
2. Remove the fuel bed, water bottle and the nozzle assembly
by twisting the red twist clips either side (left hand clockwise
& right hand anticlockwise) or push release clips on the front
of the nozzle assembly. IMAGE 1.
3. Unplug the old transducer. IMAGE 2.
4. Place the new transducer into the sump, ensuring that the
transducer is correctly placed – the tab on the transducer
should be lined up with the moulded recess in the sump
and the unit should be sitting flat. IMAGE 3.
5. Join the cable to the connector on the sump on the right
hand side. IMAGE 4.
6. Ensure that the cable is not placed above the disc on the
transducer unit. IMAGE 5.
7. To prevent the cable becoming pinched between the nozzle
and the sump, place the cable in the provided slot in the
right hand side wall of the sump. IMAGE 5.
8. Replace the sump nozzle and secure it by turning the two
red/black tabs by 90 degrees (left hand anti clockwise and
right hand clockwise, or clicked back into place if your fire
has the push fit clips. IMAGE 6.
9. Once everything has been put back together, please wait
for 5 minutes before turning the fire back on at the mains
and at the fire. This will allow the fire to reset and allow
the fire to function correctly.
