Introduction This heater has been designed for fitting in the space behind the plinth of floor standing kitchen units or other fitted furniture units. It is recommended that the heater is not installed under cupboards used for storing perishable goods. It can be accommodated in plinths with a minimum height of 12Omm, and is suitable for cupboards of 500mm width and above. Installation The installation of this appliance should be carried out by a competent electrician and be in accordance with the current IEE wiring regulations. Before undertaking installation work, ensure the electricity supply is disconnected from any relevant fixed wiring. The heater is more easily fitted during the installation of new furniture units, or on existing furniture units if they can be temporarily moved from their position against the wall. If an existing furniture unit cannot be moved, then it may be necessary to remove the back of the unit in order to gain access to carry out the wiring installation. Before installing the unit consider the location with respect to the following; • The electrical supply and cable length. • Position heater to deliver heat effectively without causing personal discomfort from overheating while standing at work surfaces etc. • Minimum plinth height of 120mm and minimum furniture unit width of 500mm.

Cutting the aperture in the Plinth Cut aperture in furniture unit plinth to This must be dimensions shown. positioned so that the minimum distance from the bottom of the aperture to the TOP surface of any floor covering is not less than 12mm and not more than 25mm. If an overhang above the heater is greater than 75mm, then a distance of at least 100mm must be maintained between the overhang and the uppermost part of the heater. Note: If fitted in corner with adjacent cupboards to left hand side of heater then a distance of at least 150mm must be maintained between the left hand end of the heater and the front of the adjacent cupboard door. * This dimension must be maintained above the top surface of any floor covering material. All dimensions in millimetres. 2. Power supply connection Check that the supply voltage details on the heater are in accordance with your electricity supply. A 2.5 metre length of inter-connecting cable is supplied. The 6 core inter-connecting cable should be routed from the plinth space to the connection box, ensuring that the cable is left with enough slack to allow removal of the appliance for maintenance. The cable must be protected from any sharp edges. a.) Remote Control Switch Panel Determine desired position for remote control switch panel above work bench i.e. 900mm minimum above floor level. It is designed for use with either a surface mounted or flush mounted box as listed in the Table opposite. The left hand column of the Table indicates the type of conduit/trunking required, if any, and the right hand column indicates the corresponding two gang box for the control switch panel.

Connect remote 2 (Plastic) control switch panel to the six core inter-connecting cable, in accordance with the wiring diagram. If the 2.5 metre length of cable supplied is insufficient and a substitute cable is used, Ensure that the conductors are of minimum 1.5mm² cross-sectional area. The same size of conductor should be used to link the switch and fuse terminals on the remote control switch panel as indicated in the wiring diagram. c.) Electrical Connection to Appliance Remove the screws securing the top, front and rear covers in order to gain access to the terminal block. Feed the 6 core flexible inter-connecting cable through the cable-clamp at the side of the heater and connect it to the terminal block in accordance with the wiring diagram. It may be necessary to remove the terminal block from its fixing while making connections to it. 3. Fitting the Rear Support Bracket The heater is supplied with a rear support bracket. Fit to the back of the appliance with the two screws supplied. Adjust the rear support bracket so that the vertical distance from the underside of the appliance to bottom of the rear support bracket equals the vertical distance from the floor in the cupboard space to the bottom of the aperture opening. The slots in the rear support bracket allow it to be adjusted to the required height. 4. Marking the Fixing Positions Slide the heater into position in the plinth aperture. Mark the six fixing holes (two on each side and two on the top Remove the heater and drill 2mm pilot holes. 5. Mounting the Heater into the Plinth When the cable connection has been made and the rear support bracket adjusted, slide the heater into the aperture ensuring that it is adequately supported and that the inlet grille is not obstructed. Use the six screws provided to secure the heater to the plinth. (See point 6 below for stainless steel grill fitting). 6. Stainless Steel Grille (BFH24RS model only). The stainless steel grille is supplied (in the plastic covering) as an attachment for the front of the heater. This should be offered up to the front of the heater before fixing the heater to the plinth. Use the six screws to secure it to the front of the heater / plinth. Operation The fan is brought into operation using the switch marked Fan on the remote control switch panel. The heating elements will not function until the fan is operating. The switches marked ‘I‘ and ‘II’ control the heating elements. The switch marked ‘I’ controls the 800W element. The switch marked ‘II’ controls the 1600W element. When both switches are ON 2400W heat output is available. Operation of Thermostat 1. The heater incorporates a variable thermostat which is controlled by a knob situated on the top right hand side of the front panel. The knob is marked *, 1 - 6, MAX, representing a temperature range of 5°C to 30°C. Lowest setting provides frost protection level. 2. Turn thermostat knob to maximum. When the room has reached the desired comfort level turn back the knob until the thermostat just ' clicks ' off. If the knob is left in this position the room temperature will be maintained automatically at the chosen level. Remember If, when the heater is switched on, the room temperature is above that selected on the thermostat knob the heater will not operate. This is as it should be, and the thermostat is performing its function correctly. Should a higher temperature be required than the one selected, then it will be necessary to turn the thermostat knob to a higher setting to bring the heater into operation. Mains Indicator Neon Lens Located at the bottom left of the front panel, the ‘mains indicator neon lens’ is to indicate when there is electrical supply to the heater and comes on when the fan switch, on the remote switch assembly is selected.
