Installation Instructions
This section describes how to set up your fire.
Before installing this appliance in an existing chimney, we recommend that;
1. You have your chimney cleaned by a competent chimney sweep.
2. You block off the chimney flue.
This procedure is important for the efficient operation of the heating unit and will also reduce heat loss up the chimney.
1. Ensure that all packing items are removed (read any warning labels carefully) and retain all packing for possible
future use e.g. in the event of moving house or returning the appliance to your supplier.
2. Before connecting the stove, check that the supply voltage is the same as that stated on the heater.
Place the stove against a wall and connect the stove to your electricity supply.
Connect the power cable to the appropriate power connector at the back of the fire
Plug the power cable into a 13amp/240volt outlet. Do not yet switch the appliance on.
Connecting the Transducer Unit + Lamps
1. Release the two red tabs by turning them by 90 degrees (see Fig 2)
2. Lift out the Sump Nozzle (Fig 3)
3. Insert lamps into lamp holders (Fig 4), carefully locating the pins into the holes (Fig 4a)
4. Push lamps firmly into place
5. Place the Transducer Unit into the sump and join the cable to the connector on the sump (Fig 5)
6. To ensure that the Transducer Unit is correctly placed in the sump, the tab on the Transducer Unit should be lined
up with the moulded recess in the sump (Fig 5a).
7. Ensure that the cable is not placed above the disc on the Transducer Unit (Fig 5b). To prevent the cable becoming
pinched between the nozzle and the sump, place the cable in the slot in the wall of the sump.
8. Replace the Sump Nozzle and secure it by turning the two red tabs by 90 degrees (Fig 6)
Filling the Water Tank
9. Place Water Tank in sink and remove cap (turn anti-clockwise to open) (Fig 7)
10. Fill Water Tank with filtered tap water only. This is necessary to prolong the life of the flame and smoke
producing unit. The water should be filtered through a conventional domestic water filter unit and the filter should be
replaced regularly. Distilled water must not be used.
11. Screw the cap back on – do not overtighten.
12. Place the Water Tank in the Sump, with the tank cap facing down and the flat side of the tank facing outward (Fig 8)

Turning the control knob to the left will decrease the temperature setting, turning the control knob
to the right will increase the temperature setting.
Control Knob ‘D’:- Controls the intensity of the flame effect.
Turning the control knob to the left increases the flame effect, turning the control knob to the right will
decrease the flame effect.
Ensure the fire is plugged in and switch it on to the full heat setting. Turn the Control Knob ‘C’ fully to the right (max
temperature setting) to warm the room rapidly. When the room temperature has reached the desired level, turn
the thermostat knob back slowly until you hear the thermostat just click 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
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 or if the chimney flue has not been blocked off effectively.. 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
