Annual servicing
It is important for the correct operation of the appliance that
servicing be carried out annually by a competent person in
accordance with gas safety regulations.
With normal use, a boiler/cooker service should be carried
out immediately after the end of the heating season. The
householder should be advised to turn off both boiler and
cooker control knobs the night preceding the day of the
service, so that the appliance will be cooled down by the
following morning, in readiness for servicing.
Before commencing any service, isolate the electricity supply
then turn OFF the gas supply at the gas service cocks.
