10.0 Servicing the Boiler

10.1 Annual Servicing
1. For reasons of safety and economy, it is
recommended that the boiler is serviced annually.
Servicing must be performed by a competent person.
NOTE: The boiler incorporates a sample point in
the flue adaptor - see Fig. 25.
2. After servicing, complete the relevant section of
the "Benchmark" Installation, Commissioning and
Service Record Log Book. This should be in the
possession of the user.
3. Ensure that the boiler is cool.
4. Ensure that both the gas and electrical
supplies to the boiler are isolated.
5. Pull the upper corners of the outercase front panel
forwards. Draw the panel upwards to disengage it
from the locating lugs (Fig. 43).
6. Undo the screws securing the combustion box
front panel. Remove the panel (Fig. 44).
7. Undo the screws securing the combustion box
inner panel. Remove the panel and examine the
insulation piece (Fig. 44).
8. At the lower right of the combustion box undo the
nut connecting the burner feed pipe to the gas inlet,
being careful not to damage the seal (Fig. 45).
9. Draw the burner out of the combustion box and
disconnect the spark lead and flame sensing lead
from the electrodes (Fig. 45).
