2. General Information
Only use filtered water in this appliance.
This model is designed to be free standing and is normally positioned
near a wall, on a non combustible surface.
Always ensure the appliance is sitting on a level, non-combustible
surface.
Please note: Used in an environment where background noise is very
low, it may be possible to hear a sound which is related to the operation
of the flame effect.This is normal and should not be a cause for concern.
If this product experiences a power surge for whatever reason the
product may cut-out.This is a normal safety feature and the product will
resume operation after 30 seconds.
Once installed, never move this appliance or lay on its back, without
draining the water from sump and water tank.
If you intend not using the appliance for longer than 2 weeks, drain the
water from sump and water tank and dry the sump.
The water tank, sump, sump lid, tank cap and air filters must be cleaned
once every two weeks, particularly in hard water areas.
The appliance should never be operated if the lamps are not working.
The lamps should be regularly inspected as described under
‘Maintenance’ and ‘Changing lamps’.

3. Installation Instructions
This section describes how to set up your fire.
BEFORE YOU START
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 to the mains supply, check that the supply voltage is
the same as that stated on the appliance.
INSTALLATION
Electric Fire Baskets: Place the appliance against a wall.
Connect the power cable to the appropriate power connector at the back
of the appliance and plug the power cable into a 13amp/240volt outlet.
Do not yet switch the appliance on.
Electric Stoves: Place the stove in to position allowing a minimum of
125mm all around the stove for ventilation.
Connect the power cable to the appropriate power connector at the back
of the fire and plug the power cable into a 13amp/240volt outlet.
Do not yet switch the appliance on.
Connecting theTransducer Unit + Lamps
1. Release the two red tabs by turning them by 90 degrees (see Fig.1).
2. Lift out the Sump Nozzle (Fig.2).
3. Insert lamps into lamp holders (Fig.3), carefully locating the pins into
the holes (Fig.4).
4. Push lamps firmly into place.
5. Place theTransducer Unit into the sump and join the cable to the
connector on the sump (Fig 5).
6.To ensure that theTransducer Unit is correctly placed in the sump, the
tab on theTransducer 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 theTransducer
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).

6
Filling the WaterTank
9. Place WaterTank in sink and remove cap (turn anti-clockwise to open)
(Fig 7).
10. Fill WaterTank with filtered tap water only.This is necessary to pro-
long the life of the flame and smoke effect 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 WaterTank in the Sump, with the tank cap facing down and
the flat side of the tank facing outward (Fig 8).
Assembling the fire
13. Place the Fuelbed on top of the WaterTank.
The appliance is now ready for use.

4. Operating the Fire
This section describes how to activate your fire using either the manual
controls or remote control.
MANUAL CONTROLS
The manual controls are located beneath the hinged flap. (See Fig.9 for
Manual Control lay out).
Switch ‘A’:- Controls the electricity supply to the Fire.
Note:This switch must be in the ‘ON’ ( I ) position for the Fire to operate.
Switch ‘B’:- Press once to turn on the flame effect.This will be
indicated by an audible beep. Although the main lights operate
immediately it will take a further 30 seconds before the flame effect
starts.
(Electric Stove models only)
Press again to give flame effect and half heat.This will be
indicated by two beeps.
Press again to give flame effect and full heat.This will be
indicated by three beeps.
Press again to return to flame effect only.This will be
indicated by one beep.
Press to put fire in to standby mode.This will be indicated by one
beep.
Control Knob ‘C’:- Controls theThermostat setting. (Electric Stove Models only).
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.

8
SETTING THE THERMOSTAT (Electric Stove models only)
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.
THERMAL SAFETY CUT-OUT (Electric Stove models only)
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 a 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.
GETTING THE DESIRED FLAME EFFECT
1.The flame control knob ‘D’ (Fig.9) may be turned up or down to give a
more realistic effect.
2. Generally the flames appear more realistic when the flame control is
turned down.
3. Give the flame generator time to react to changes you may make.
4.The appliance will use less water if the flame effect is set to a lower
level (control knob ‘D’).
5. Do not tilt or move the appliance while there is water in the tank or
sump.
6. Make sure that the appliance is on a level floor.

9
Press once to turn on Flame effect only.
This will be indicated by one beep.
(Electric Stove models only)
Press once to turn on Half Heat and Flame Effect.
This will be indicated by two beeps.
Press again to turn on Full Heat and Flame Effect.
This will be indicated by three beeps.
To switch from Half or Full Heat to Flame Effect only, press
followed by
Standby.
This will be indicated by one beep.
REMOTE CONTROL OPERATION
On the control panel, Switch A (see Fig. 9) must be in the ‘ON’ ( I)
position in order for the remote control to operate.
There are 3 buttons on the remote control. (See Fig.11)To operate
correctly the remote must be pointed towards the front of the grate. (See
Fig 16).The remote control functions are as follows:
