This heater must be used on an AC ~ supply only and the voltage marked on the heater must
correspond to the supply voltage. Before switching on, please read the safety warnings and
operating instructions. Please retain this user’s guide for future reference
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 o the chimney ue.
This procedure is important for the ecient operation of the heating unit and will also reduce heat
loss up the chimney.
Ensure that all packing items are removed (read any warning labels carefully). Retain all packing
for possible future use e.g. in the event of moving or returning the appliance to your supplier.
Installing the Appliance;
1. Clean the area where the re will be installed e.g remove ash residue from an existing replace.
2. Hold the re by the sides of surround and gently manoeuvre into position.
3. Plug the re into a 13amp/240 volt outlet. Ensure that the supply cable is not trapped under
the re such that it might cause it to be damaged.
4. Ensure that the draft excluder (rubber strip) is tted to the channel on the base of the product.
Connecting the Transducer
1. Gently lift out the fuelbed and carefully set aside. (Fig 3)
2. Remove the water tank by lifting upwards and outwards. (Fig 4)
3. Remove the nozzle by unclipping and lifting upwards and outwards. (Fig 5)
4. The transducer will be inside the sump. Remove from its bag.
5. Place the Transducer unit into the sump and make the connection.
6. Locate the tab on the Transducer unit into the moulded recess in the base of the sump (Fig 6)
7. Ensure that the cable does not obstruct the Transducer disc. To prevent the cable becoming
pinched between the nozzle and the sump, place the cable in the slot in the wall of the sump.
(Fig 7)
Filling the Water Tank
1. Gently lift out the fuelbed and carefully set aside.
2. Remove the water tank by lifting upwards and outwards.
3. Place the water tank in sink and remove cap, Anti-clockwise to open. (Fig 8)
3. Fill tank with ltered tap water only. This is necessary to prolong the life of the ame and
smoke producing unit. The water should be ltered through a conventional domestic water
lter unit and the lter should be replaced regularly.
6. Screw the cap back on, do not over tighten.
7. Return the tank to the sump, with the tank cap facing down
8. Gently place the fuelbed back into position.
When the water tank is empty, the ame and smoke eect shuts o, you will hear 2 audible beeps
and the digital display will display

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.
