Important notes prior to servicing
10.1
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.
6 Ensure that the boiler controls and room thermostat
(if fitted) are set to the User's requirements.
7 Tell the User the system pressure and show them
the position of the safety valve discharge pipe.
8 Show the User how to reset the overheat thermostat
and how to restart the boiler if it goes to 'Lock-out'.
Leave this Instruction manual with the User.
Ensure the User information pack has been given
to the Householder.
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 recorded
in the Service Log in the Boiler Handbook. This
information may be required to validate the Grant
extended warranty.
IMPORTANT
Before starting any work on the boiler, or fuel supply
please read the health and safety information given in
Section 15 on page 61.
1 Check the flue terminal and ensure it is not blocked
or damaged.
2 Run the boiler and check the operation of its
controls.
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.
Check the expansion vessel air charge. See Section 6.6.
Check the system pressure. Refill, vent and re-
pressurise the system as necessary. See Section 7.1.
4 Check that any ventilation openings are adequate
and are clear. See Section 5.6.
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 nozzle fitted.
