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. Undo the two securing screws from the rear of
the top panel. Remove the panel (Fig. 22).
6. Disengage the front panel from the retaining
magnets and hinge forwards. Unhook the panel
from the lower hinge pins (Fig. 22) and place to
the right hand side, taking care not to stretch the
earth wire.
7. Undo the wing nuts securing the combustion
box top panel (Fig. 23). Remove the panel.
8. Undo the disconnecting union on the gas inlet.
Remove the screw securing the burner ignition
control to the gas valve. Draw the control off the
