General
This heater has been designed for tting in the space behind the plinth of oor standing
kitchen units or other tted 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 120mm, and is suitable for cupboards of 500mm
width and above.
Installation
Before undertaking installation work, ensure the electricity supply is disconnected
from any relevant xed wiring.
The heater is more easily tted 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 eectively without causing personal discomfort
from overheating while standing at work surfaces etc.
• Minimum plinth height of 120mm and minimum furniture unit width of 500mm.
WARNING: The installation of this appliance should be carried out by a competent
electrician and be in accordance with the current IEE wiring regulations
and any local or insurance regulations.

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
oor covering is not less than 14mm.
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 tted 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 oor 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 tted with 1.4 metres of exible cable type
H05VV-F size 2 x 1.0mm for electrical connection. The cable may be used to connect
the heater to the xed 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 furniture unit 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. The isolating switch must be accessible after installation of the
unit and the furniture.
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 unit is level. 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 xing 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.
