B diffuser vs 9 slot Carlin EZ Gas Burner

adasilva

140,000 BTU New Yorker Steam boiler with a Carlin EZ gas burner conversion kit installed in 06. Was doing some reading and according to the literature the 9 slot diffuser would be better for short flame pattern for shorter combustion chamber units. Not certain what would dictate the use of B vs the 9 slot diffuser other than the original oil burner that was in the boiler to start with? And what effect on the boiler & or gas usage between the two diffusers if any would be? I understand that the orifice also plays a part in this as well and would it be worthwhile to have all of this torn down to verify that it is what it should be?

What is the model number of your boiler?

In general checking the orifice size, gas pressure, air settings, draft, then checking combustion. If the numbers are where they should be, I doubt changing the diffuser would help much.

If you can get the best numbers, then maybe change it, only if all the settings are correct.

There's a reason it's called 'EZ'. They give you all the parameters for initial set up, and they are usually really close.
Installing a Carlin EZ gas, I usually call the world famous BG (don't know if he wants his name out there) after it's running. Tell him all the parameters, all my combustion numbers, and he tells me what if anything is needed to tweak it better, of if that's where I'm suppose to be.
You've had the EZ gas in for 12 plus years. Are you experiencing any problems?
Do you have it checked with any regularity by a competent tech with proper skills/tools/instruments?

There is a label on the boiler that says the unit it was supplied with for oil was a Beckett AFG w/ F3 head and 3 3/8" disc & 85 80 degree A nozzle if that is of more help?

@STEVEusaPA Ok so my numbers are pretty good as I have posted the analisis info in the strictly steam area. Stack temp is high and that brings some curiosity. It has always been noisy on initial firing like a boom and my bill has been,high last month alone was more than twice what I paid the year before. I've skimmed & vented mains balanced the radiators so there really cannot be more that I can do at this point in time to gain more efficiency. What I have found that the install was bad right out of the gate and wondered if that also went for the conversion burner. As for prices the state I live in is # 3 on the most expensive for utilities but last month really wasn't that cold so more than double was alarming.

@adasilva

Instead of guessing, why don't you just call Carlin tech support and ask them. Give them all the info on the boiler and burner you have.

This is what they do

adasilva

@EBEBRATT-Ed yes that would be a good idea wouldn't it? Sometimes the easiest answer is right in front of my nose!

@adasilva

Carlin has OEM guides on their website. You may find the information their

I know who you mean, and he's one of the best in the business.

@adasilva , where did you say you were located?

STEVEusaPA

It helps to either stay in the same thread or put a link to the thread (or just re-post the combustion numbers).

IIRC, the consensus was probably overfired, too much draft.
So before calling tech support, it's best to have a qualified tech who can provide Carlin with all the correct info regarding draft, gas pressure, orifice size (confirmed) and combustion numbers.
Or, if you can't find someone here, call Carlin and ask them who they recommend for your situation and location.
Otherwise Carlin will most likely ask you to get the information and call back.

@Steamhead I'm in RI near the Massachusetts border.
@STEVEusaPA that's a valid point and I have contacted someone per the recommendation of a gentleman from here based in RI but I haven't heard back since we talked and he expressed the same sentiment about "it's been so long if there was a problem it would have shown up already". My issue is if the installer didn't know and the previous home owner didn't care how would anyone know?

Did you call @Tim McElwain ?

adasilva

Yes and spoke with the gentleman he recommended. We'll see if he can make it out this week. If not I'm going to reach out to NE Steamworks and see if they can help.....
