Installation Instructions
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.
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 fire will be installed.
2. Remove wall bracket from the back of the appliance, by removing the 2 screws that the wall bracket
is fixed with. From the base of the fire chassis, a minimum distance from the floor of 300mm -
600mm, from the side wall of 625mm and 150mm minimum form the top of the product to any shelf
above it. (Fig 1)
3. Fix the wall bracket to the wall making sure it is level, using the wall plugs and screws supplied for
block walls.
4. Hang the appliance o the fixed wall bracket. Rotate the safety fixing bracket on the base of the
product so that the fixing hole is exposed. Mark this hole and remove the appliance from the wall.
5. Fix plug to the wall in the marked position.
6. Hang the appliance back on the wall fixing bracket and fix the appliance in place using the screw
supplied through the safety fixing bracket.
7. Make sure the unit is switched OFF.
8. Plug the fire into a 13amp/240 volt outlet. Ensure that the supply cable is not trapped under the fire
such that it might cause it to be damaged.
Connecting the Transducer
1. Gently lift out the fuel-bed and carefully set aside. (Fig 4)
2. Remove the water tank by lifting upwards and outwards. (Fig 5)
3. Remove the nozzle by un-clipping and lifting upwards and outwards. (Fig 6)
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 7A)
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 7B)
Filling the Water Tank

producing unit. The water should be filtered through a conventional domestic water filter unit and the
filter should be replaced regularly.
5. Screw the cap back on, do not over tighten.
6. Return the tank to the sump, with the tank cap facing down.
7. Gently place the fuel-bed back into position.

Adaptive Start
The built-in electronics in this appliance hava a learning function with regards to how long it takes to
heat up a room. Having learnt how quickly it can heat up your room, the appliance is able to turn on
at just the right time in order to get the room up to a comfortable temperature when you want it. For
example, if you get up at 7am, you would normally have to guess when to turn the heating on in order
for it to pre-heat the room in time. Depending on how cold it is outside, this could mean the room is still
cold when you have to get out of bed, or mean that its been warm for half an hour before it needed to
be. Adaptive Start means that if you select 21ºCat 7am, the heater will turn on exactly when it needs to
in order to meet this target, running for shorter periods of time when the weather is mild, and ensuring
the room is nice and warm in the winter.
The Adaptive Start function will automatically activate when you use the Timer Mode.
