Noisy Carlin EZ gas conversion burners
Have any of you had complaints? I am getting 2 or 3 calls a week.
Also complaints on the 120 volt gas valve making a noise when closing.
What have you found?

Now i have ...
only done 2, both is Smith 8 series boilers....No complaints. One customer actually was happy it was quieter than the EZ oil that came out.

Roar and initial valve noise
I had a Smith G8-3 and EZ Gas installed in October. When they started it up and were running the combustion test the thing was roaring pretty good, they had to increase the air to 24% to quiet it down some. It's still roaring but not as bad if it was optimally tuned so it's not as efficient as it could be. The 02 is 4.3%, CO2 9.4% and the stack is 433F with an ambient of 50F.
The gas valve was noisy as well, sounded like someone was rapping on the pipe with a bat. A lot of noise was being transmitted through the 1" gas pipe to the floor joists so I wrapped the pipe with silicone rubber sheet at the clamp points and that cut some of the clunk. Over the last few months the noise has gotten less and less, maybe the valve is wearing in??

noisier
The one I had put in for me in October is noticeably noisier than the Carlin EZ oil burner that it replaced, but I don't have anything else to compare it to. No valve noise, just roaring.

TIm
are they complaining about the roar, or is there something else, I had one a while back that complained about a whistle, went and checked it and found nothing, heard nothing never heard back. The carlins have always been a little loud, the waynes are noticeably more quite...
I haven't heard the 120v gas valve or noticed a noise... Ill ask my tech, he swapped out a carlin ez1 for an ez gas about 3 weeks ago...

EZ gas
Tim, we've sold a lot of EZ gas conversion burners and quite a few systems with it installed. Only a couple of noise complaints to my knowledge that I believe have been corrected. One whistle that was an undersized flex gas supply that should not have been used.

Burners
We try to stay away from Carlin burners as we have had some issues with them. We prefer Fuelmaster burners. Last year, we got stuck using two Carlin burners on Smith 8 Series, one on gas and one opn oil. The gas one was very noisy. It required the replacement of the retention head of another design which Smith provided. That solved the noise issue.
-
Hmmm
Gotta wonder if that's why Smith stopped offering it as a package (G-8)?

Mine
I have the ez-gas on my 8 series 5 section. She rumbles a little more than it did with the ez-1, no gas valve noise.

Generally
the EZ-Gas sounds like a typical flame-retention oil burner. We had one job where the combination of an EZ-Gas in a Slant/Fin Intrepid TR-40 and that particular chimney produced a noticeable harmonic rumble, but we got that down to a manageable level with help from our local Carlin rep, Bruce Graham.
One of the nice things about the Midco radial-flame low-NOx burner is that it doesn't produce any rumble at all. Still waiting for them to come up with a proper steam control system for it.

yes to noise complaints
the frequency is different due to the light burner. The oil has lots of cast iron parts to muffle the noise is what I figure. Also tuning by way of a combustion analyzer is critical to keep the noise down. No gas valve noise complaints though. The fresh air intake cover helps with noise complaints if they exist after tuning.
Cost is what you spend , value is what you get.

Retention head?
The rumble on my EZ gas is almost all low frequency so the cover really has no impact on the noise level. The overhead gas line is 1" and the feed down to the boiler is 3/4" steel pipe, it clocks out to about 109,000 BTU's.
The installers had to increase the air to quiet the burner down to a livable level but it's still louder than the old AFG burner was on the V75 oil fired system.
I'll have to contact Carlin to see if a different retention head would help control the noise on my G8-3 boiler. Is there a model number I should ask about?

B diffuser
The EZ-Gas model was specifically for the Smith G8 (mine is the G8-3) and it's marked as having the B diffuser plate. i did not see the burner before it was in the boiler, the manifold pressure was checked and it's 3.5" with the boiler running (the input was 11" in October).

Steamhead
Could using the wrong diffuser cause excessive rumble? I can't find anything about the 9S diffuser in any of the manuals. They list 'A", "B", or "C". My installer said he was not going to fire the boiler as high as recommended,"it wasn't necessary". He was going to fire it about 150000btus. He didn't mark the orifice size. Below 175 requires a change from "A" to "B" diffuser, and my airtube is marked 9S....

Talked to an installer
here locally (RI) who has installed over 250 Carlin EZ Gas burners without any noise complaints.
I have a feeling these noisy burners are not installed correctly and not set up properly.

Noise is realitive
I am positive the units I have installed are correctly tuned and mounted. Anyone who says no noise complaints after hundreds of installs to me is like the wholesaler who says "No one else has had an issue with that part, boiler, or fixture". I like the Carlin. I feel it is a good burner. I also know some people are bothered by the noise and other burners are out of tune. You need to tread lightly as some of the noise complaints will be valid and some will not be. If guys are just setting them by the manual without testing the combustion They are causing issues and making a bad name for a good burner. I had one in New Bedford That a guy with 30 years installing for the the gas company installed and it was out of tune and the orifice was 3 yes 3 drill sizes too small. I was called in because the house would not heat and they said it was the steam piping.

Years ago I was
With Pete Axeman in his lab and he was showing me the Carlin gas burner. It was very loud. He said, "watch this", and put on a 1'section of I think it was 4" pipe on the inlet and the burner quieted right down. Really an amazing difference. Maybe there is something here for the EZ as well
