Hi all, Hoping you can help me out.
I purchased a house with a Buderus Logano G215 paired with a Riello 40 F5 burner that provides DHW and 3 zones of heating via circulators feeding hydro air units.
We had it serviced in Feb '19 by the HVAC company that replaced our Hydro Air handlers and Outdoor condensers and they screwed it up and it kept locking out and puffing back for months. The techs didn't know how to work on this equipment.
After some research I realized I needed an HVAC company who knows Buderus and Riello, so I found one. They sent out their service manager who got us all fixed up. He explained how the other company installed all kinds of things wrong and baffles backwards, but he clearly knew his stuff. This was at the end of July '19 and we've been running smooth ever since.
Fast forward and we have a new issue that I'm hoping to get some help with.
The Riello has always been noisy and we can hear it fire below our family room. Today I noticed the burner running and firing to flame for 4-5 seconds and then for 15-20 seconds it sounds like the pump is running but not firing.
The odd thing is the safety isn't cutting it off and I haven't had to reset the burner. This pattern is not at all the usual. I can't even call is short-cycling, almost "micro-cycling" but the burner has been running for many minutes like this, more than 30-45.
The boiler appears to be getting up to temp and other than the very annoying sound and weird pattern it seems "working" in a very inefficient way.
I'm going to call for service tomorrow, but figured I'd ask thoughts/suggestions in case I can't get them out. I've done lots of burner work on many homes and properties over the years where they had beckett or Carlin burners. I've graduated from working on my own equipment unless necessary, but have left this Riello to the pros based on research when we bought this place, especially after the first guys screwed it up.
I saw how easy it was to test the PhotoCell so I did that quickly and wiped it down and also tried bleeding to see if there was air in the oil line, but didn't change anything.
THANKS
