When the water tank 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 return.
Setting the Thermostat
Plug in and switch on the fire to the full heat setting. Turn the Control Knob 'C' fully away from you (max temperature setting)
to warm the room rapidly. When the room temperature has reached the desired level, turn the thermostat knob back slowly
until the thermostat just clicks off. The heater will then maintain the room temperature at the chosen level.
Note: Should your heater fail to come on when the thermostat is at a low setting, this may be due to the room temperature
being higher then the thermostat setting
Thermal safety cut-out
A thermal safety cut-out is incorporated in the fan heater to prevent damage due to overheating. This can happen if the heat
outlet was restricted in any way. If the cut-out operates, unplug the heater from the socket outlet and allow approximately 10
minutes before reconnecting. Before switching the heater back on remove any obstruction that may be restricting the heat
outlet, then continue normal operation.
Caution: In order to avoid hazard due to inadvertent resetting of the thermal cutout, this appliance must not be supplied
through an external switching device, such as a timer, or connected to a switch that is regularly switched on and off by the
utility.
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 fixed level on the wall.
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 to a low setting.
6. Give the flame generator some time to react to changes you may make on the flame control knob.

1. Leaving the flame effect on, lift out the fuelbed and water tank. (See Fig.3) and lift out the nozzle (See Fig.4)
2. View the lamps from a distance in front of the fire and observe which lamp needs to be changed.
3. Press switch 'A' to off (0) position (See Fig.2), 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 water tank by lifting upwards and place in a sink.
6. Remove the sump as described in the Cleaning Section.
7. Remove the defective lamp, by gently lifting vertically and disengaging the pins from the lamp holder, (See Fig.4 and 4a).
Replace with an Opti-myst, 12V, 50W, Gu5.3 base, 8º beam angle, coloured lamp. (To purchased replacement lamps go to the
