PUMP PRIMING FUNCTION
During a lockout, the burner can be purged for 30 seconds to eliminate any air from the pipes and filters of the fuel oil
supply pipes.
To avoid damaging the pump, do not repeat this procedure more than 5 times.

POST-PURGING
Post-purging is a function that allows you to maintain the air purging even after the burner is switched off in the absence
of the heat request for a pre-set time.
The burner switches off the flame when the heat request thermostat opens, cutting off the fuel supply to the valves.
The post-purging function is not performed:
- after a lockout;
- if the heat request is interrupted during pre-purging.
Post-purging occurs:
- if the heat request is interrupted during the safety time;
- if the heat request is interrupted during normal operation.
NOTE:
If during post-purging there is an extraneous light or a parasite flame the burner goes into lockout after 25 seconds.
If during post-purging there is a new heat request, the post-purging time is halted, the fan motor
i
stops and a new burner
operating cycle starts.
