11.3 Maintenance

If during the annual inspection combustion results indicate that the boiler is no longer
operating at the optimum level, additional maintenance should be carried out as
follows:
- Wash the heat exchanger through using clean warm water. If badly contaminated it
may be necessary to use the special cleaning tool (can be supplied as an option).
Compressed air can also be used, but care should be taken to ensure that the
disturbed dust etc. does not contaminate the rest of the boiler and controls.
- Clean the burner assembly (using compressed air only).
- Clean the fan.
- Re-commission boiler.
NOTE:
1. Please ensure that the mains power supply is isolated before components are
disconnected from the boiler for maintenance.
2. Care should be taken when stripping the boiler for maintenance making sure that
all parts nuts, washers and gaskets etc. are kept safe, clean and dry.
3. Following cleaning, the boiler should be re-assembled in the reverse order re-
placing gaskets and joints where found necessary.
4. All general cleaning should be carried out with a soft brush or damp cloth to avoid
damaging components. (Solvents must not be used).
5. If parts are found to be badly contaminated please check that the plant room is
kept clean and free of dust etc.
6. Heat exchanger access hatch securing nuts to be tightened using an M6 spanner
of the correct length to a max. torque of app. 7.5 Nm.
