recommend having the boiler inspected and serviced at regular
intervals.
4 Maintenance and cleaning of the boiler must be carried out at least
once a year by a qualified technician.
4 Have the flues swept at least once a year or more, depending on
the regulations in force in your country.
CAUTION
Maintenance operations must be done by a qualified
4
engineer.
We recommend taking out a maintenance contract.
4
Only original spare parts must be used.

4
