1.9 Life cycle
Burner controls have 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 burner controls 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 burner control is to be replaced by authorized personnel.
* The designed lifetime is not the warranty time specified in the Terms of Delivery
