Before commencing any mechanical servicing the appliance should be isolated from the electrical
supply and the gas service cock on the appliance closed. All parts that are removed during a
service operation should be replaced in reverse order, ensuring correct seals are made and wires
are connected correctly. During the service remove any debris from within the appliance. When
gas-carrying components are serviced the appliance must be tested for gas tightness after re-
assembly. On completion of a service carry out a full functional test of all appliance components
and ensure system controls are operating correctly.
