To ensure continued efficient operation of the appliance, 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 a
year should be adequate. It is the law that any service work must
be carried out by a competent person, such as British Gas or
other CORGI registered personnel.
The boiler incorporates a flue sampling point on the top panel in
front of the flue outlet. If the service engineer has suitable
equipment to analyse the flue gas, the plastic cap may be
removed and a 6mm inside diameter sample tube fitted. Do not
forget to replace the plastic cap after use.
Before commencing any service operation, ISOLATE the mains
electrical supply, and TURN OFF the gas supply at the main
service cock.
Service the appliance by following the full procedure detailed
below:
a)
Remove the casing front panel by unscrewing the panel
retaining screw and lifting off the panel.
b)
Remove the sealed chamber front panel (4 screws).
c)
Remove the combustion chamber front panel (7 screws). Take
care not to damage the insulation.
Do not attempt to light the burner with Front Panel
removed.
d)
Remove the 4 screws securing the burner on the gas manifold.
e)
Unscrew and remove the two screws securing the control
panel in the upright position and pivot the panel forwards.
f)
Remove the two spark and one detection electrode leads from
the electrodes.
Check that the injectors fitted in the gas manifold are free from dirt
and debris. If necessary clean the injector orifice carefully using a
soft brush or vacuum cleaner. Do not use a wire brush or any
abrasive material.
It is not necessary to remove the injectors.
If there are
signs of injector(s) being blocked please call the Halstead Service
Department.
a)
Inspect the ignition and detection electrodes in situ. If
necessary clean using a soft brush. If either the electrode or
the ceramic insulation show signs of damage or wear, replace
the electrode(s).
b)
Check that the alignment of the ignition and detection
electrodes are as shown in Figure 34. Adjust by carefully
bending the tip of the electrode rod whilst supporting the base
of the rod. Do not put any pressure on the ceramic insulation.
g)
Remove the burner by lifting it forward with reference to
Figure 33.
h)
Inspect and if necessary clean the main burner ports using a
soft brush or vacuum cleaner. Do not use a wire brush or any
abrasive material.
