What to do if the Ferroli Boiler has no main burner ignition?
- J
  Joanne AguilarAug 18, 2025
  If the main burner doesn't ignite, it could be due to several reasons. First, check if there is a power outage and wait for the power to return. Another reason may be obstructed nozzles, in which case you should clean the nozzles thoroughly. A faulty gas valve can also prevent ignition, requiring you to repair or replace the gas valve. Finally, the fume thermostat might have intervened; check for any flue obstructions and manually reset the fume thermostat.

  If you notice a smell of unburnt gas from your boiler, it could be due to several reasons. The boiler shell might be dirty, requiring a check and clean. Insufficient flue draught can also cause this issue, so check the efficiency of the flue draught. Another cause might be insufficient air change, in which case you should increase room ventilation. Lastly, incorrect flame adjustment (excess) can lead to this problem; check the flow to the gas meter and the main burner pressure.

What to do if the pilot goes out on a Ferroli PEGASUS 23 T Boiler?
- J
  Joseph HuntAug 23, 2025
  If the pilot light on your Ferroli boiler keeps going out, there are a few potential causes. It could be a faulty thermocouple, which would need to be checked or replaced. A poor flame can also cause this; adjust the flame with the screw on the gas valve until it envelops the thermocouple. Finally, poor contact with the coil could be the issue; try tightening the union on the gas valve.

Why is there no temperature increase with my Ferroli Boiler working?
- K
  Kelly RussoAug 26, 2025
  If you're not seeing a temperature increase while your boiler is running, several factors could be responsible. First, check gas consumption. The boiler shell might be dirty, requiring a check and clean. Also, the boiler might be insufficient for the heating system's demand, so ensure it is adequate.

Why is there no pilot ignition in my Ferroli Boiler?
- A
  Ann LopezAug 28, 2025
  If your boiler's pilot isn't igniting, start by checking if the gas cock is open. Air in the pipes could also be the problem; vent as specified in the section on lighting. A pilot nozzle obstruction can prevent ignition, so clean the nozzle with compressed air. Finally, insufficient gas flow can be a cause; adjust the flow with the valve screw.

What to do if my Ferroli PEGASUS 23 T Boiler is creating condensate?
- K
  Kelly NormanAug 30, 2025
  If your boiler is producing condensate, it might be due to an incorrect thermostat setting; try setting the thermostat to a higher temperature. It can also be caused by insufficient gas consumption, make sure gas consumption complies with that specified.

Why does my Ferroli PEGASUS 23 T shut down for no apparent reason?
- T
  tinaaguilarSep 2, 2025
  If your boiler shuts down unexpectedly, it could be due to a couple of reasons. The fume thermostat might have intervened, so check for any obstructions in the flue and manually reset it. Alternatively, the safety thermostat might have intervened, indicating a need to check the correct circulation of water in the system.

What to do if there is no ignition discharge in my Ferroli PEGASUS 23 T Boiler?
- N
  Nathan HuffSep 4, 2025
  If there's no ignition discharge in your boiler, it could be due to a faulty ignition piezo, which would need to be replaced. Alternatively, the ignition electrode might be broken or incorrectly positioned, requiring replacement or correct positioning. A false contact between the terminal and cable can also cause this; screw down the terminal onto the igniter cable.

Why does my Ferroli PEGASUS 23 T Boiler get dirty easily?
- F
  Frank JohnsonSep 7, 2025
  If your boiler gets dirty easily, the incorrect flame adjustment might be the reason. Check the main burner flame and ensure that gas consumption is correct for boiler output.
