• To check the UV photocell and lock, proceed as follows:
- Start the burner.
- After at least one minute from ignition remove the UV photocell
from its seat and simulate a flame failure by covering it with
a dark cloth. The burner flame must turn off, the equipment
must repeat the ignition phase from the beginning and shut
down as soon as the flame turns on.
- The equipment can only be released manually by pressing
the release button. The burner shutdown efficiency test must
be performed at least twice.
• Check that the boiler thermostats or pressure switches are
operating correctly (they must cause the boiler to shut down
when they intervene).
