What Kibble said.
I see this occasionally, although I've never seen one where only one unit fires.
If there's a single T-stat, it should fire both boilers, no?

Yeah, OK. I've just seen them with a single aqua stat, single t-stat, boilers run in parallel.

Also, copper risers? That is an unfailing sign of an installer who doesn't understand steam systems.

K-copper? It doesn't matter what type of copper. It expands and contracts and the joints fail.

Im just saying that sometimes there is more than one option,especially on a small boiler . My first question on that particular boiler from what i see in the picture is where is the insulation on the lines,and since im willing to bet it was asbestos who removed and how did they remove it.

No option on steam. Iron. Pipefitting.

Who'd have ever imagined that Copper.org would think it's OK?
Of course there's lots of stuff one can do if they're so inclined.
Personally, I pay attention to the guys installing and working on steam systems for the last century. Other's can listen to professional organization webmeisters.

Not only do the joints leak, but the rest of the copper gets perforated. I don't know what flies in other parts of the country, but we rarely see copper risers on a steam system, and when we do, it's obvious why it's such a bad idea. Type K brazed copper? Never seen it on a steam system.

Like I said, there's lots of ways to do stuff. I'm all for engineers saying it's OK and doing it any way they want on their jobs.
The engineers I work with know that copper is a bad way to go.
Everyone gets to choose. I choose what I know works.
Are there a lot of steam systems in Louisville, Nebraska?

Ive got an old 93hp kewanee in one of my buildings in omaha,no copper on that one but its also the size of my old chevy cube van and heats 27 apartments and 6 commercial bays. There are many updated steam boilers around omaha,and many of them have k copper plumbed into them theyve been running for years without issues. Many of the hot water boilers I still work on around omaha still run steel piping,some of them have been repiped in copper it depends on when they were installed.

So is there anything in a mechanical code book that says you can never use K-copper under any circumstances in any steam boiler? I mean since most of you guys(not all of you)seem to like to get your answers directly from a book.

And yup, it's piped with a bullheaded tee... Any chance there was an outdoor reset for that system? Could you post a picture of your boiler install?

No you need to lighten up ,i went through the same bunch of crap from you guys on the A coil post when i talked about using oversize coils with you guys rattling on about i didnt know what i was talking about,then i posted the manufacturers suggestions for over size coils proving it was legitimate. As i was basically told years of field experiance meant nothing if it wasnt designed by an engineer or in a code book . So now im just asking where it says in the code that K-copper cannot never be used in a steam boiler system,and no the experiance from old guys whove been in the field for 100 years doesnt count as you guys have already said.
