Hello all.
I'm looking for advice to help my heating engineer fix my problem! He actually installed the unit.
It’s a 3 year old oil boiler, a Firebird with C26 Riello burner.
It’s been running fine since installation, but went into Lockout a couple of weeks ago.
The engineer first changed the kerosene pump saying it was very stiff to turn, which seemed true actually. He also changed the nozzle. This made no difference to the problem though … still kept locking out after a few minutes.
He noticed that the motor which drives the kerosene pump was getting hot to touch after 5 minutes of use, so then changed that too. However, again this made no difference to the problem … still kept locking out after a few minutes … and the new motor also gets very hot to touch. New capacitor came with the new motor.
Frustrated, after a few days on non-use, and a very annoyed wife, I fired the boiler up myself. I noticed quite a lot of blue smoke coming from the vent, whereas previously it had always been clear, with only a hint of light colour detectable on cold days.
The engineer returned for a 3rd visit, and dealt with the blue smoke by adjusting the ‘air damper adjustment screw’ … I’m looking through the Riello manual as I type! Lol. He plugged a monitor in whilst doing this. During this 3rd visit, I know he pulled the whole Riello unit out and took much of it apart. He’s gone again now saying that he’ll have to speak with Riello. That’s fair enough.
My own little bit of diagnosis:
The boiler will fire up and continue running until something tells it to stop!
It’ll happily heat up the domestic hot water as well as the house radiators, but as soon as you start/stop a hot water tap, or it receives a signal from the Honeywell Wi-Fi thermostat (saying the house reached the desire temp), it goes into lockout.
At this point, the kerosene motor will be very hot, and you won’t be able to reset the lockout for several minutes. I’m presuming a safety temp control thermostat is causing that?
My question is: could the motor be spinning too fast, hence the reason for becoming very hot?
Could this be driving too much kerosene into the burner, hence that blue smoke?
Could it be that the new capacitor is faulty?
Or perhaps something’s simply gone wrong in the Control Box?
If anyone has any ideas on this one, it would be very much appreciated!
Cheers, guys.
