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

Changing a

Transducer

5 6

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.
