ENGLISH
EXPECTED LIFESPAN
The expected lifespan of burners and relevant components depends very much from the type of application on which the burner is installed, from
cycles of delivered power, from the conditions of the environment in which it is located, from maintenance frequency and mode, etc.
Standards about safety components provide for a project expected lifespan expressed in cycles and/or years of operation.
Such components ensure the correct operation in standard (*) operating conditions, with periodic maintenance according to the instructions
contained in the manual.
The table below shows the project expected lifespan of the main safety components; approximately, operating cycles correspond to the burner
activations.
When this expected lifespan limit has almost been reached the component must be replaced with an original spare part .
IMPORTANT
warranty conditions (laid down in contracts and/or delivery or payment notes, if necessary) are independent and do not refer to the
expected lifespan stated below.
(*) "Normal" operating conditions means applications on water boilers and steam generators or industrial applications compliant with the standard
EN 746, in environments with temperatures within the limits provided for in this manual and with pollution degree 2 in compliance with annex M
of the standard EN 60335-1.

must be replaced.
