Life cycle 
Burner controls LAL 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 in the 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. 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
