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
shown. This must be 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. 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 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.
Internal Cleaning & Maintenance
To help prevent the build up of dust and fluff in the
heater it is advisable to apply the soft brush
attachment of a vacuum cleaner to the grille
occasionally (fig. 1).
From time to time it may be necessary to remove the
heater from the furniture unit so that the interior of
the heater and the heater compartment can be
cleared of any accumulated dust or fluff by means of
a vacuum cleaner (fig. 2).
To remove, unscrew the six fixing screws and
withdraw the appliance from the plinth.
To gain access to the inside of the appliance remove
the screws securing the top cover.
Clean the interior of the heater using the soft brush
attachment of a vacuum cleaner, taking care not to
damage the fan.
Refit the top cover. The interior compartment of the
furniture unit should also be cleared of dust and fluff
using the vacuum cleaner nozzle (fig. 3).
Remount the heater in the plinth ensuring the rear
support bracket is still adjusted correctly.
The electricity supply to the heater can now be
switched back on.
Safety – overheat protection
For your safety, this appliance is fitted with a thermal cut-out. In the event that the product overheats, the cut-out switches
the heater off automatically. To bring the heater back into operation, remove the cause of overheating, then turn off the
electrical supply to the heater for a few minutes. When the heater has cooled sufficiently reconnect and switch on the
heater.
If the cut-out operates repeatedly, contact your supplier
Procedure for resetting the cut-out;
A. Disconnect the electricity supply to the appliance either by switching off at the isolating switch panel.
B. Determine what has caused the cut-out to operate and rectify.
(Note : This should only be undertaken by competent persons with experience of repairing electrical appliances
and in full knowledge of the possible hazards involved ).
C. After a short time delay to allow the appliance to cool down, all that is required to return the heater to normal
operation is to switch the electricity supply back on.
