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. Procedure 1. Cutting the aperture in the Plinth Cut aperture in furniture unit plinth to dimensions This must be positioned so that the shown. 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. dimensions in millimetres. All 2. Power supply connection Check that the supply voltage details on the heater are in accordance with your electricity supply. The appliance is fitted with 2 metres of flexible cable type H05VV-F size 3 x 1.5mm for electrical connection. The cable may be used to connect the heater to the fixed wiring of the premises through a suitable connection box. The supply circuit to the heater must incorporate a double pole isolating switch having a contact separation of at least 3mm. The power supply 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. 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 (BFH24TS 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 1 Switch on electricity supply to the heater. 2 Switching the switch marked “ l “energises blower and illuminates neon indicator. 3 Select " l " and switches marked " ● " and “ 1 + 1 + ● 1 + 1 + + = Cooling + = 800W heating + ● + ● ● ● ● “ as required: = 1600W heating = 2400W heating 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. Cleaning & User Maintenance WARNING: DISCONNECT SUPPLY before carrying out maintenance. General Cleaning External appearance can be maintained by wiping occasionally with a damp cloth; for stain removal, a weak soap solution can be applied, then wipe dry.
