Important notes prior to servicing
8.1
The User must be advised (and demonstrated if
necessary) of the following important points:-
1
How to light and turn off the boiler and how to
operate the system controls.
2
The precautions necessary to prevent damage to
the central heating system and to the building, in
the event of the boiler not being in operation
during frost conditions.
3
The importance of servicing the boiler to ensure
safe and efficient operation. This should normally
only be required once a year.
4
The type of fuel used.
5
That any servicing or replacement of parts must
only be carried out by a suitably qualified engineer.
3
Ensure that all water/fuel system connections and
fittings are sound. Remake any joints and check the
tightness of any fittings that may be leaking.
If the boiler is used on a sealed central heating
system, check the system pressure, check the
operation of the pressure relief valve and check the
expansion vessel air charge. See Section 5.6.
Refill, vent and re-pressurise the system as
necessary. See Section 5.11
4
Check that any ventilation openings are adequate
and are clear. See Section 4.7.
5
Remove any sludge/water from the fuel tank by
opening the sludge valve at the lower end of the tank.
6
With the fuel supply valve closed, clean/replace the
filter element and clean the filter bowl.
7
Flexible fuel supply pipes should be inspected
annually when the boiler is serviced and replaced
every two years. If in doubt replace the pipes.
Warning: Before servicing, set the boiler On/Off
switch to Off, isolate the electricity supply and close
the fuel supply valve. Allow the boiler to cool.
The data label on the inside of the case side panel will
indicate the fuel used and the nozzle fitted.
To ensure 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.
Servicing and replacement of parts must only be
carried out by a suitably qualified engineer.
Important: Details of every service should be
entered in the Service Log, in the Boiler Handbook.
This information may be required to validate the
Grant extended warranty.
