13.1 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.
2. After servicing, complete the relevant Service Interval
Record section of the Benchmark Commissioning Checklist
at the rear of this publication.
3. Ensure that the boiler is cool.
4. Ensure that both the gas and electrical supplies to the
boiler are isolated.
5. Slacken the screws securing the facia panel. Lift the
outercase panel so that its securing tabs are clear of the
facia. Remove the panel, allowing the facia to hinge down
(Fig. 52).
6. Remove the screws securing the inner door panel. Lift the
panel slightly to disengage it from the studs on top of the
case (Fig. 54).
7. Note the positions of the sensing tube(s) (28 HE has two
- one tube on 18 & 24 HE) on the fan spigot and three
wires on the fan motor and remove them (Fig. 53).
8. Slacken the screws on the fan spigot outlet pipe clamps.
Ease the clamps inwards over the pipe (28 HE). On 18 & 24
HE models undo the securing screw at the left hand end of
the pipe and the clamp at the right.
9. Draw the outlet pipe away from the boiler.
10. Remove the four screws securing the combustion box
door and remove the door (Fig. 54).
