Mrs. Plvmber is watching Oscars.
Wife is watching the Oscars and I'm not even allowed to talk.
Here's something much more interesting (if the link works). A recent boiler installation of mine in Fort Greene:

Oh. I didn't think the picture would load so large.
Don't bother with the link, I guess. It's the same picture.

the only thing that i dont like is instead of a probe type low water cutoff i would way preferred a float type lwco/ automatic water fill..why did you not do that?

I think you tend to work on commercial boilers, eman, so you like the McDonnel-Miller #47-2, don't ya?
In a residential installation, we use the low water cut-offs that the manufacturers provide with their boilers. 99 times out of 100, that's a probe-type device. They have their reasons.
We back them up with line voltage cut offs to save the boiler if the first cut off should fail.
We also wire them to low voltage feeders like the Hydrolevel VXT with digital counter and settable fill rates.

that drop header is one pretty piece of work

MasterPlumber, I love looking at your work. Kinda like window shopping. Do you think one day you could post some pictures of a residential oil setup with an indirect storage.

Wow, that looks fantastic. Is it hard to change out the pigtail connection to the pressuretol? Mine is definitely not Brass. It is a hard black rubber looking connection.
What purpose does the upper and lower guage valves serve? For maintenance on the guage glass?

Very cool thanks for posting this

Colonel, I don't service or install oil boilers/burners, I'm a gas heating specialist, but I'll see what I can do.
Hobbyboy, it's not a difficult job, you just have to be careful not to snap off the small threads in the fittings they screw in to or crack the boiler section.
The gauge valves allow you to clean or replace the glass.
Amybnyc, I don't quote prices here, but I'm not one of the cheap guys.
I do free estimates all day long if you're interested.

I see some of the worst work in NYC and most of it is in
Fort Greene, Clinton Hill and Park Slope.
Buildings in those neighborhoods have been patched together since forever.
These good installations cost me a lot of money in materials, qualified labor and follow up visits so my prices to the Client can be on the high side, too.
As does shoddy workmanship, quality catches up to you.

Is there a difference btwn the primary and secondary pressuretrols? Or is one just a back up for a failure in the other?

btw ...there is no comparison between mp's installations and the results had by people who post on brownstoner saying that replacing a boiler is a one day job costing $1500 over the cost of a boiler... notice the near piping..it makes a huge difference as compared to just inserting the boiler beneath whatever existed previously...what i always tell my clients is that you are paying for knowledge, not labor

Thanks, eman. (your check is in the mail)
Arches, in this case for safety's sake, and in the case of a multi-family by Code, the secondary pressuretrol will trip a reset button and break power to the boiler if the high pressure setting is reached.
The primary unit is what we call the operating control as it reaches the high limit, then shuts the boiler, then automatically restarts it based on a differential or low setting.

why didn't you seperate the manual reset pressure-control from theregular acting pressure-control to avoid sediment build-up?Not a bad installation,does the pressure-control tee doubles as the skimm tee?

By code, they only need to be set up as they are here with their own pigtails. In larger applications, we would give them their own tappings. The 1" skim port is on the right side of the boiler.
