Before switching on, please read the safety advice and operating instructions. General Information Only use filtered water in this appliance. This model is designed to be free standing and is normally positioned near a wall. Always ensure that the appliance is sitting on a level surface. Although this heater complies with safety standards, we do not recommend its use on deep pile carpets or on long hair type of rugs. 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’. 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 the stove, check that the supply voltage is the same as that stated on the heater. INSTALLATION Hold the fire by the sides of surround and gently manoeuvre into position. Place the fire against a wall and connect 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. Ensure that the supply cable exits at the back of the fire, at the right or left hand corner to suit your supply socket location and is not trapped under the fire such that it might cause it to be damaged. Do not yet switch the appliance on. Connecting the Transducer Unit + Lamps 1. Release the two red tabs by turning them by 90 degrees (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) Assembling the fire 13. Place the Fuelbed on top of the Water Tank and Mist Nozzle (Fig 9) 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. (Fig.10 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 either with or without heat. 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. Press again to give flame effect and half heat. This will be indicated by two beeps. again to give flame effect and full heat. This will be indicated by three beeps. Press 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 the Thermostat setting. 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. SETTING THE THERMOSTAT 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 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.10) 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 fire will use less water if the flame effect is set to a lower level. 5. Do not tilt or move the fire while there is water in the tank or sump. 6. Make sure that the fire is on a level floor. REMOTE CONTROL OPERATION On the control panel, Switch A (Fig.10) must be in the ‘ON’ ( I ) position in order for the remote control to operate. There are 3 buttons on the remote control. (Fig.12) To operate correctly the remote must be pointed towards the front of the grate. (Fig 17). The remote control functions are as follows: Press once to turn on Flame effect only. This will be indicated by one beep. 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. Standby This will be indicated by one beep. Maintenance GENERAL TIPS Only use filtered tap water in this appliance.
