Maintenance intervals
For optimum, long-term reliable functioning of the heating
boiler, and in order to be able to claim under the terms of the
manufacturer's warranty, the heating boiler must be inspected
and maintained at least once a year (under normal operating
conditions) by an officially recognized installation and service
engineer. The term "normal operating conditions" means that
the heating boiler is used to provide central heating and/or hot
water to no more than one single-family dwelling.
In all other cases, the heating boiler must be inspected and
maintained by an officially recognised installation service engi-
neer every 2,500 burner operating hours.
