8 Maintenance
Always wear the proper protective clothing and shoes when servicing the boiler.
Wearing jewelry and loose clothing can contribute to unsafe situations.
8.1 Safety
In order to keep the R2000 in a safe working condition, the boiler should be inspected and serviced at
least once every year and cleaned if necessary.
Frost protection
When boiler is not in operation for a long period of time, the heat exchanger should be protected
against frost. This can be achieved by draining water from the heat exchanger.

Inspecting the draught diverter
Remove the inner and outer access panels on the draught diverter to allow internal inspection of
the draught diverter and flue baffles.
Heat exchanger (external inspection)
As you inspect the inside of the draught diverter, the top of the heat exchanger can also be inspected.
Check for dirt and sooting. For cleaning the heat exchanger, refer to chapter “Cleaning”.
After removing the burner, the combustion chamber and the underside of the heat exchanger can
easily be inspected by using a mirror for example.
Heat exchanger (internal inspection)
Internal inspection must be carried out by qualified and authorised personnel.
Sight glass
A sight glass can be found on the right hand side of the burner assembly for inspection of:
- boiler ignition
- combustion
- pilot flame.

2 Release the two brackets which attach the burner to the boiler frame.
3 Disconnect the spark plug, ionisation caps, servo-motor plugs and solenoid value plugs and
