11.0 Servicing the Boiler

11 .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 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. Slacken the screws securing the facia panel.
Lift the outercase panel so that its securing tabs
are clear of the facia. Remove the panel (Fig. 39).
6. Remove the screws (2 on Instant 80e, 4 on
Instant 105e) securing the inner door panel. Lift
the panel slightly to disengage it from the studs on
top of the case (Fig. 40).
7. Note the positions of the two sensing tubes on
the outlet elbow and three wires on the fan motor
and remove them (Fig. 41).
8. Slacken the screws on the outlet sealing collar.
Ease the collar upwards as far as possible
(Fig. 41).
9. Remove the four screws securing the
combustion box door and remove the door
(Fig. 40).
