ROUTINE SERVICING
To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary

GENERAL INFORMATION
1.6.1
Fault finding indicators (LEDS)
The appliance is fitted with a safety cut-out thermostat. In
the event of overheating this will interrupt the power supply
and prevent the appliance from functioning.
If this occurs, allow the appliance to cool, turn the selector
switch summer/winter to “
“ position and release it imme-
diately, then turn it back to the previous position (see fig. 2).
If the cut-out condition is repeated, turn off the electrical sup-
ply and consult your installer or service engineer.
1.6.2
Temperature/pressure gauge
The gauge (A fig. 1) on the facia panel indicates the approxi-
mate system pressure. If the normal running pressure is
seen to decrease over a period of time there is a water leak
and you should consult your installer or service engineer.
1.6.3
Electrical supply
The mains plug used must be a 3 pin type to BS1363, and
fused at 3 A. THIS APPLIANCE MUST BE EARTHED.
NOTE: an interruption in the electricity supply whilst the
burner is alight may cause the overheat thermostat to
operate. If this is suspected, turn the rotary switch to “
“
position and release it immediately, then turn it back to
the previous position.
TO CONNECT A PLUG
As the colour of wires in the mains lead of this appliance may
not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
the wire which is coloured green and yellow must be con-
nected to the terminal in the plug which is marked with the
letter E or by the earth symbol - or coloured green and yel-
low; the wire which is coloured blue must be connected to
the terminal marked with the letter N or coloured black; the
wire which is coloured brown must be connected to the ter-
minal marked with the letter L or coloured red.
1.6.5
Ventilation
If the appliance is installed in a cabinet, the latter MUST NOT
be used for storage purposes.
Any ventilation provided for the appliance during installation
MUST NOT be blocked and a periodic check must be made
to ensure that the vents are free from obstructions.
