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
