Gas burner issues

Did they provide you with documentation of the draft and combustion measurements they made? I suspect the tech that set it up doesn't know what they are doing but it could be a problem with the size or routing of the vent as well. It is a matter of getting it set up correctly, probably nothing wrong with the burner or boiler.1

This. You might want to get in touch with @Charlie from wmass and see if he'll come to Windsor- he has a LOT of experience with these burners.mattmia2 said:Did they provide you with documentation of the draft and combustion measurements they made?

Hi. Thanks for the response! Unfortunately they didn’t leave me anything giving exact measurements. They had a machine that ran some diagnostics and I heard them drilling. The only report I have is from the final install on 6/25/2019. After the first visit that I paid for, the technician told me that it was 99% the chimney and 1% that it was very hot (which made me question if I had to call him every time it was hot out). The second time, there was two technicians and they adjusted a vent that “changed the hot air that tripped the switch”. They didn’t leave any paperwork as this was a free call. Do you think if it happens again, that I’m better off calling another HVAC company?0

The liner should have been done at the time of the conversion. Heck, it should have been done when the boiler was replaced by the previous owner.
The BV switch as I'm sure you know is a pretty important item. Get it fixed, with documentation showing draft and combustion. You don't want to wake up dead one morning.
I would start with the burner orifice, clock the meter for actual BTU input, and go from there. Do you know if anyone inspected the burner assembly or opened the boiler?
I don't understand the changing the vent settings to minimize backflow. If that's the way it was explained to you, then the tech has very poor bs production capabilities. Or very good. Either way, you need someone with experience.

Indeed, the oil gods are laughing their heads off. Well, what's done is done.
CNG does not have, to my knowledge, the personnel to correctly install, never mind adjust and service, this equipment -- but they're terrific salesmen.
Call @Charlie from wmass -- he's up in Springfield, and busy as a one arm paper hanger, but he's among the best, is very familiar with Carlin burners, and will get you going. A word of warning, it's very unlikely that it is a problem with either the burner or the boiler, however: it is, very likely, that it is a fundamental problem with the installation and venting, and may not be inexpensive to fix.Br.

Utica does not approve the installation of a gas power burner on their oil boilers.Cost is what you spend , value is what you get.

So does that mean it will work but might void the warranty? It will work but is a code issue? Might work? Won't work?Charlie from wmass said:Utica does not approve the installation of a gas power burner on their oil boilers.

That's interesting- Utica supplies cast-iron wet-base boilers to Columbia, and Columbia offers EZ-Gas burners to go with them. Ask me how I know that.Charlie from wmass said:It should work but DOES void boiler warranty.

Hello everyone, thanks for the advice and insight as to what could possibly be causing these issues. I Spoke to the HVAC company about what they did yesterday to troubleshoot the problem. According to them, they ran some tests and found a back draft into the system. They made adjustments to some vent, and then used a device to run a report and make sure it “passed”. They also said that the newly installed liner was not properly attached to the boiler, which they also took care of. Im still nervous, because the same testing method was done two weeks ago when I had the problem originally. I did email Carlin, and I did ask for a copy of the combustion report (which they didn’t print).0

And this was the original report when it was installed last year.0

First things first- that burner is not dialed in properly.
1-The stack temp (TS) should be at least 325° F to avoid flue has condensation.
2- The Carbon Monoxide (CO as measured directly, COc as measured air-free with the excess air (EA) factored out) is too high. This may be caused by the undersized flame or not enough combustion air, or the flame hitting something it shouldn't. OK, federal standards allow more CO than this, but they are also too high.
Also, this Utica (Utica Heating) is not the same Utica (Utica Radiator Co) we're used to. It, and the companion gas boilers, appear to be re-branded Dunkirks.All Steamed Up, Inc.

Utica heating is Utica boilers, just the previous series. I like their atmospheric 16 series gas boiler as it still uses 2 1/2" tappings instead of the 2" they now use on the peg. But I digress.
Those combustion numbers are bad. I wonder if the bothered brushing out the boiler before converting?Cost is what you spend , value is what you get.

I wonder if it needs cleaning now from operating like that.Charlie from wmass said:Those combustion numbers are bad. I wonder if the bothered brushing out the boiler before converting?

It also depends on how the readings were obtained. Positioning of the probe for the tester can be a big factor.0

Why not call Carlin and ask them to recommend someone who they know. They can also have the tech either call Carlin's territory manager or tech support while they are there, to help trouble shoot.
"Fingers crossed" is not the sign of a professional...you should be worried, annoyed and upset.
BTW, looking at your picture, how tight is the room that boiler is located?
Did anyone confirm enough combustion air?

Hey everyone. Thanks again for all the responses. I reached out to Carlin via email and phone and haven’t gotten a response. In the mean time, I asked the company that came out to produce the last two combustion test results, which they couldn’t. They came out first thing this morning and ran the test under four operating conditions. I don’t know if these results are good, or better than the initial analysis. If not acceptable, I think my next step is to find a different company and see if they can fix it...or look into a new unit. The size of the room came up in our discussion, but the company said “well the town approved it”.0

Is it just me or has that tester not been calibrated since 2010?Cost is what you spend , value is what you get.

Do we really need to be clear on that? Not everyone gets the pun?ChrisJ said:Just so we're clear, you don't wake up dead.
You literally don't wake up, that's sort of the problem and all.
Combustion numbers...I think we're underfired for sure.There was an error rendering this rich post.

Not just you. Wöhler is pretty good about doing calibrations quickly, so there's no excuse for not having it done in ten years.Charlie from wmass said:Is it just me or has that tester not been calibrated since 2010?

The only reason I do not have my own analyzer is due to them needing calibration frequently.Steamhead said:

The more recent combustion tests are better, stack is hotter which is dropping the Co to a more normal level. 8.5 Co2 is pushing the envelope a little in my opinion, does not leave much margin for error
I know the boiler is a wet base but it may need a blanket on the botton. One of their notes says short cycling which does nothing to improve combustion....quite the opposite.
Because the stack temp is borderline too low you can't cut the fire so the short cycling problem should be fixed.
It say "ran on heat" "ran on hotter" Don't know if it has a tankless or indirect but a longer burn time would help
The promising note is the combustion numbers are getting close to where they should be with the hotter stack temp
Maybe the boiler wasn't warmed up enough when they first tested it
A cold pot of water on a gas stove will make some CO0
