CHANGING LAMPS
If the flame and smoke effect 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, lift out the fuelbed and water tank.
2. It should be possible to view the lamps with the nozzle in place and observe which one needs to be changed.
3. Put Switch 'A' in the 'OFF' (0) position, and unplug the fire from the mains.
4. Leave the appliance for 20 minutes to allow the lamps to cool down before removing them.
5. Remove the sump as described in the Cleaning Section.
6. Remove the defective lamp, by gently lifting vertically and disengaging the pins from the lamp holder,
(See Fig.4 and 4a).
Replace with a Dimplex Optimyst, 12V, 45W, Gu5.3 base, 8º beam angle, coloured lamp.

CLEANING
Warning – Always press Switch 'A' to the 'OFF' (0) position (See Fig.10) and disconnect from the power supply before
cleaning the fire.
We recommend cleaning the following components once every week, particularly in hard water areas:-
Water Tank, Sump, Nozzle, Tank cap and seal, Air filter.
For general cleaning use a soft clean duster – never use abrasive cleaners.
To remove any accumulation of dust or fluff, the soft brush attachment of a vacuum cleaner should occasionally be
used.
Water tank
1. Remove water tank, as described earlier, put into sink and empty water.
2. Using the supplied brush gently rub the inside surfaces of the cap paying particular attention to the rubber ring in
the outer groove and the centre rubber seal.
3. Put a small quantity of washing up liquid into the tank, refit the cap and shake well, rinse out until all traces of
washing up liquid are gone.
