This heater must be used on an ~alternating current supply (~) only and the voltage marked on

the heater must correspond to the supply voltage.

Do not use this appliance in series with a thermal control, a program controller, a timer or any

other device that switches on the heat automatically, since a re risk exists when the appliance

is accidentally covered or displaced.

DO NOT use the heater on deep pile carpets or the long hair type of rugs, or less than 750mm

(30”) away from any overhanging surface. Keep combustible materials such as drapes and

other furnishings clear from the front, sides and rear of the heater. Do not use heater to dry

A fan heater can provide heating in cold weather. A distance of 1 metre (3 feet) must be maintained

between the front of the heater and any surrounding furniture, overhanging curtains or other

obstructions.

To reduce heat loss and to prevent any chimney up draft aecting the operation of your inset re

we recommend they the chimney ue is sealed o.

hear a sound which is related to the operation of the ame eect. This is normal and should not

be a cause for concern.

The sump and the water tank in this product are treated with a biocidal product, Silver Biocide

in order to control harmful or unwanted organisms. This conforms with the latest relevant ISO

garments on the appliance, or obstruct the air circulation around the appliance, for instance by

curtains or furniture, as this could cause overheating and a re risk.

The appliance carries a DO NOT COVER warning

Warning: In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this

appliance must not be supplied through an external switching device, such as a timer, or

connected to a circuit that is regularly switched on and o by the utility.

This heater must be used on an AC ~ supply only and the voltage marked on the heater must

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

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.
