9 Servicing

9.1 Initial Inspection

To ensure the continued safe and efficient operation of
the boiler it is recommended that it is checked and
1
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 the law that all servic-
ing work is carried out by a competent person (Corgi
registered).
• Isolate the mains electricity supply by disconnecting
the plug at the socket outlet (if there is only an
isolating 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.
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
sooting.
9.2 Cleaning the burner and primary heat exchanger
• Turn off the boiler.
• Isolate the electrical supply to the boiler.
• Remove the boiler case as described.
• Turn off the gas service valve.
Improtant!
Before starting any maintenance work:
Note!
The boiler is fitted with a combustion analysis
test points on the front of the combustion
chamber cover. A suitable combustion analyser
can be connected to these points to establish
the combustion performance of the boiler.
