1.5 ROUTINE SERVICING
To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary
at regular intervals.
The frequency of servicing will depend upon the particular
installation conditions and usage but in general once a year
should be adequate. It is the law that any service work must
be carried out by a registered person.
1.6 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. 25).
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. 24) 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.
