1.11 Life cycle
The burner management system has a designed lifetime* of 250,000 burner startup
cycles which, under normal operating conditions in heating mode, correspond to approx.
10 years of usage (starting from the production date given on the type field). This
lifetime is based on the endurance tests specified in standard EN 298.
A summary of the conditions has been published by the European
Control
Manufacturers Association
(Afecor) (www.afecor.org).
The designed lifetime is based on use of the LMV37.4 according to the manufacturer’s
Data sheet and Basic documentation. After reaching the designed lifetime in terms of
the number of burner startup cycles, or the respective time of usage, the LMV37.4 is to
be replaced by authorized personnel.
* The designed lifetime is not the warranty time specified in the Terms of Delivery
1.12 Disposal notes
