if the start criteria have already been met.
Fan run-up time
FanRunupTime
Residence time in phase 22.
Once this time has elapsed the burner drives to pre-
purge position.
Pre-purge
PrepurgeTmeGas
PrepurgeTmeOil
Time from reaching the pre-purge position until driving to
ignition position. The time is divided into the phases 30 to
34. The W-FM remains in phase 30 for the time set under
PrepurgeTimeTl1…
and then drives to phase 34 via
phase 32. The rest of the time, the W-FM remains in
phase 34, or at least for the duration set under
Pre-

PrepurgeSafeOil
Pre-purge time after the following occurrences:
Lockout or safety shutdown
Power failure
Standby longer than 24h
PrepurgePt1Gas
PrepurgePt1Oil
For the duration of this time, auxiliary actuator 3 (FGR) re-
mains in phase 30 and the fuel actuators remain in
standby position. The air determining actuators remain in
pre-purge position.
PrepurgePt3Gas
PrepurgePt3Oil
Minimum duration in phase 34. The air determining actu-
ators and auxiliary actuator 3 (FGR) remain in pre-purge
position. The fuel actuators remain in standby position.
Pre-ignition
Nozzle circulation
PreIgnitionTGas
PreIgnitionTOil
Residence time in phase 38.
Once this time has elapsed, fuel is released for ignition.
On heavy oil burners without return flow temperature
sensor, nozzle circulation can be extended via
Pre-
IgnitionTOil
.
Oil pump ON time
MinONTmeOilPump
Residence time in phase 36 (heavy oil operation only).
In heavy oil operation, the time in phase 36 can be exten-
