7.1 Notes.
(a) To ensure the continued efficient and safe operation
of the appliance it is recommended that it is checked
and serviced at regular intervals. The frequency of
servicing will depend upon the particular installation
and usage, but in general once a year should be
enough.
(b) It is the law that any servicing must be carried out by
a competent person.
(c) Make sure the fire front is cold before carrying out
any servicing.
(d) BEFORE SERVICING ISOLATE THE GAS AND
ELECTRICAL SUPPLIES.
(e) After servicing of parts always test for gas
soundness with a suitable leak detection fluid.
To test the gas tap apply leak detection fluid to all
joints, light the burner and check all the joints for
leakage at all tap settings.
WARNING: Take care as the burner flame is fully
exposed.
(f) Carry out functional check on controls.
(g) After removing or disconnecting any pipe work
always make sure that it is refitted correctly and
does not interfere with the fitting of the fire front.
(h) Unless stated otherwise reassembly of all
components should be in the reverse order to that for
removal.
(j) It is recommended that the back boiler be serviced at
this time.
Refer to Back Boiler Installation and Servicing
Instructions.
