Inspection and maintenance intervals

Regular maintenance and service is recommended to
ensure permanent safe and efficient operation of the
boiler. The frequency of maintenance and service de-
pends upon the individual installation conditions and
upon the use the appliance is put to. An inspection must
be performed once a year.

It is a legal requirement that all maintenance
work be only performed by trained personnel
approved at the time by the Health and Safety

ance over a long period, only genuine Vaillant spare
parts may be used when undertaking maintenance, serv-
ice and repair work. Any spare parts which might be re-
quired are contained in the current Vaillant spare parts
