CARE OF YOUR APPLIANCE AND SYSTEM
4 2.1
Annual servicing of your appliance is required
to maintain safety and efficiency of its
operation. Therefore it is recommended that
the appliance is serviced at least once a year
and that the whole of the heating system be
checked at the same time by a qualified
installer. If it is known or suspected that a fault
exists on the boiler then it MUST NOT be used
until the fault has been corrected by a
COMPETENT PERSON. It is essential that the
instructions in this booklet are strictly followed
for safe and economic operation of the boiler.
SERVICING SHOULD BE CARRIED OUT BY A
COMPETENT PERSON.
NOTE: An anti-cycling device is fitted to the
heating function. When the boiler reaches
its set maximum temperature it will not
operate on heating for about 3 minutes but
the domestic hot water function will always
operate on demand.
