Maintenance - Dimplex DANVILLE Opti-myst DNV20AB Manual

Tips for using your appliance.
1. The Opti-myst flame and smoke effect will last for approximately 9hrs when the product is turned to full flame, and
approximately 12hrs when set at minimum. These times are a guideline only and can vary.
2. Do not tilt or move the fire while there is water in the tank or sump.
3. Make sure that the fire is on a level floor.
4. The flame control knob 'D' Fig.2 may be turned up or down to give a more realistic effect.
5. Sometimes the flames appear more real when the flame control knob is turned down.
6. Give the flame generator some time to react to changes you may make on the flame control knob.

Changing lamps.
If 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, lift out the fuelbed and water tank. (See Fig.3)
2. It should be possible to view the lamps with the nozzle (See Fig.4) in place and observe which one needs to be
changed.
3. Put Switch 'A' in the 'OFF' 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 Opti-myst, 12V, 45W, 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.)

Cleaning.
WARNING – ALWAYS DISCONNECT FROM THE POWER SUPPLY BEFORE CLEANING THE HEATER.
We recommend cleaning the following components once every 2 weeks, 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 to clean the outlet grille of the fan heater.

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.
