9.1 Initial Inspection

To ensure the continued safe and efficient operation of
the boiler it is recommended that it is checked and ser-
viced 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 the 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 only an isola-
ting switch 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 multimeter after any service work and
after exchanging any electrical component.
Note!
The boiler is fitted with a combustion analysis
test point. A suitable combustion analyser can
be connected to this point to establish the com-
bustion performance of the boiler.
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.
• Check the heating and water system, in particular the
condition of radiator valves, evidence of leakage from
the heating system and dripping hot water taps.
Functional check of boiler operation
• Carry out a functional check of the boiler operation as
prevoiusly detailed.
• Remove the appliance casing as detailed and operate
the boiler by fully opening a hot water tap. Inspect the
burner operation through the viewing window. Check
that the flames are evenly covering the surface of the
burner. Inspect for signs of excessive flame lift or soo-
ting.
