Description of functions
When the system is switched on for the
first time, after a power failure or safety
shutdown, after a lack of fuel or after the
system has been out of operation for 24
hours, the pre-ventilation period of 25
seconds begins.

- blower pressure is monitored.
- the combustion chamber is monitored for
flame signals.
At the end of the pre­purge period:
- ignition is switched on.

Monitoring
The flame is monitored by an
photoresistor. The burner switches to lock-

flame.
