Start-up procedure
Check that the Operator panel display shows the heat request
and "OFF UP0" for fuel "0" or "OFF UPr1" for fuel 1: this means
it is necessary to set the modulation curve of the burner.
Access the Parameters Level referring to "Access procedure with
password".
The display screen displays the parameters group 400.
P
Confirm with the key "i/reset"
The display shows "run"
Confirm with the key "i/reset". The burner starts up.
The display shows all the phases and relative times in sequence.
The phases are listed in the section List of the phases (gas oper-
ation).
Phase 22:
Start of the fan motor.
Pump motor start-up (only for oil operation).
Phase 24:
The burner goes to the pre-purging position, the air servomotor
opens the damper at 90°.
Phases 80, 81, 82, 83 (only with gas operation):
These phases relate to the valve seal test.

Phase 38:
The ignition phase begins and the spark goes off.
Phase 40:
The fuel valves open (the safety time count begins). Using the ap-
propriate visor check there is a flame and that the combustion pa-
rameters are correct. if necessary, vary the degrees of opening/
closing of the air and fuel servomotors.
When operating with oil, the valves only open with
the consent of the minimum oil pressure switch. If
necessary adjust the minimum pressure switch or
check the fuel flow.
