    BF Riello. You will need to remove some baffles.

    Is it chimney vented now, or direct vent?

    Its a shame because they're nice burners. But a 3% gain in efficiency isn't a great ROI vs cost. I don't think I've seen the condensing one in real life.

    Its 2025 in an old post. I want to say Mine was installed in December of 2008 and has over 10,000 hours on it. Finally an honest tech came to the house and said they no longer have anyone able to service this - aparantly they have been taking my money for a few years with only vacuuming the chimney.

    They are offering the burner swap out- but Obviously I do not trust them. I would be willing to pay someone to come and clean it /service it annually - I'm in lower connecticut, but I cant find anyone.

    I actualy like this burner and the control. I have considered learning how to do this myself, but I doubt there is anyone left to tech me how to do this.

    📢 If anyone knows of anyone in the CT southern area or NY/CT border please let me know. I rather not go into this season now knowing I literally have no service. I am will to have it be a side gig for the right person.

    Thank you.

    Yes, Wonderful burners. Alot of discontinued parts nozzles hard to get

    However, the nail in the coffin is Bio. They hate bio blends and your wonderful state has madated (renewables) bio blends that cannot be monitered. The LoNox hates Bio. A gummed up burner with hard to get parts. Not worth the aggravation.

    Part of the Clean air initiative that has been voted in NY CT and RI.. I'll stop there

    Really have to pay attention to what is being voted in.

    The BE is a great burner. A tech needed to be certified by Buderus to service them. If they've gone the way of the Dodo, then a Riello isn't a bad idea. Some baffles will likely need to be removed. And it is a positive pressure boiler, so the burner flange and air tube must be sealed. And 90% of the techs don't understand the 2107 Logomatic.

    If I could find a tech, I would continue on - this my reaching out here. Alas, I am giving up hope.

    Is there any real technical information on making this conversion? Since no one knows the boiler as it is, I want something to give them to do it right. I am not concerned about the Logomatic - I have programed that myself!

    I am tempted to wait until it stops running to make the change, but I also know thats a bad idea. I'm just tired of fighting.

    Thanks in advance for any info you may have.

    As long as the boiler is chimney vented, and not sidewall, then the Riello gets set up per the OEM specs for whatever size G115 you have. If the BE is drawing outside combustion air (which it should be, because CO2 is set according to the outdoor combustion air temperature), then you could go with the BF Riello to keep things quiet. The standard 40 series F3 or F5 Riello is much louder than the BE. If an OEM burner flange and air tube aren't being used, then they must be sealed with high temp silicone as its a positive pressure boiler.

    When testing, Buderus wants 0 to slightly positive draft over fire, so like I mentioned earlier, some baffles might need to be removed to achieve that, as well as bring up the stack temperature if too low.
