6. Servicing

To ensure the continued safe and
efficient operation of the boiler 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 per year should be
adequate. It is law that all servicing
work is carried out by a competent
person (CORGI registered).
IMPORTANT:
Before starting any maintenance
work:
•
Isolate the mains electricity supply
by disconnecting the plug at the
socket outlet (if there is an isolating
switch only remove the fuse from
the switch).
•
Turn OFF the gas supply at the gas
service valve fitted to the boiler.
•
Always test for gas soundness and
always carry out functional checks
after any service work and after
exchanging any gas carrying
component.
•
Always check earth continuity,
polarity and resistance to earth with
a multi-meter after any service work
and after exchanging any electrical
component.
Note: The boiler is fitted with a
combustion analysis test point (7, fig.
44). A suitable combustion analyser
can be connected to this point to
establish the combustion performance
of the boiler.

6.1 Initial Inspection

Before commencing any servicing or
maintenance work, carry out an initial
inspection of the system as follows:-
Inspect the flue, pipework and electrical
connections for indications of damage
or deterioration.
Inspect the air supply and ventilation
arrangements of the installation,
ensuring that the requirements of
Section 3.5 are met.
Operate the boiler by turning the
maximum hot water temperature
control (4, fig. 44) to '9' and fully
opening a hot water tap. Inspect the
burner operation through the viewing
window. Check that the flames are
burning evenly over the full surface of
the burner. Inspect for signs of excessive
lifting or sooting.
Check the heating and hot water
system, in particular the condition of
the radiator valves, evidence of leakage
from the heating system and dripping
hot water taps.
