Transformer

@ September 11, 2012 10:04 PM in How can I get a W-R 1361 zone valve to run off a Taco ZVC404 Zone Valve Control?

He can use the transformer from the zone board.

Looks like every apartment building in NJ.

Agreed. Fix those leaks! Don't trust a lazy contractor.

Heat

@ September 11, 2012 8:16 PM in Third floor heating?

Air is lazy, but you can move water anywhere. I'd vote to try for a hot water system.

I'm in NJ, but I'd be willing to make a trip into upstate NY if you have trouble finding a reliable local contractor.

Update.

We did this conversion yesterday. Here is a link to our Facebook page with pictures. The quality is awful, but it gives you the basic idea.

I have a few issues with the Carlin installation procedure. The flange is a little tricky to keep straight and level when tightening down the set screws. And we'll be installing a union after the gas valve from now on, to make redrilling the orifice a lot easier. It was also annoying to have to remove the gas valve electrical connections just to screw in my manometer fitting. I'll use a short 1/4" nipple next time.

Otherwise, it's a great little burner. I'm officially converting to Carlin.

Leak.

@ September 11, 2012 12:35 PM in Dirty boiler water

I would rather not live with the leak. There are always ways to fix a broken nipple. You may even be able to replace the internal parts/washer of the drain valve.

A/C

@ September 10, 2012 7:58 PM in A/C ducts put into working indirect radiator bays

I bet it saved a lot of time and money to do it that way. Sadly, it may just be a complete waste of the A/C. Most indirect heaters have a outdoor air source, or if not, an open duct in the basement. Personally, I don't like to condition the air outside of my house. 

Options

@ September 9, 2012 10:51 PM in How can I get a W-R 1361 zone valve to run off a Taco ZVC404 Zone Valve Control?

Any standard 24 volt relay would work. It's hard to predict the perfomance of a 'passive priority'.

Yup

That's a really low load. Where did those numbers come from?

Wiring

@ September 9, 2012 8:58 PM in How can I get a W-R 1361 zone valve to run off a Taco ZVC404 Zone Valve Control?

I've thought about this 5 different ways, and can't put it all together without using an isolation relay energized on the valve's 2&3. The open contacts go to the priority zone's TT. Priority zone end switch jumped out. Indirect aquastat goes to valve's 4&5.

It's always amazing, that years ago, people could engineer such an awesome system. But, nowadays, we can't even get the piping right....with instructions provided!!

Valve.

@ September 7, 2012 6:22 PM in Why is this here?

That is a check valve. Could be in the return line of the steam baseboard. Do you have more pictures?

@ September 6, 2012 5:03 PM in "Novel Thoughts" from Dan's newsletter

Just like the use of shadows as a character in old film.

In "older" music, you get the same image. "The heat pipes cough."

I think once we traded the coal shovels for thermostats, we lost that whole part of our culture. Every time I'm in an old basement, I imagine myself as the dad from A Christmas Story, banging and rustling...a cloud of soot rising out of the vents.

Great.

@ September 6, 2012 4:51 PM in Heads-up on our friends' new site

Now I'll spend more time reading about work....and more time learning how to ignore my wife yelling at me for reading about work.

Test

@ September 6, 2012 2:19 PM in We replaced a steam boiler for a freelance photographer.

I'm going to bring my wife's good camera on the next install to experiment with photos. I think the trick to a good looking picture is definitely in the post-editing.

Try changing setting 680 to 1 instead of 2. That should let the temperature drop lower than normal.

Otherwise, I don't think there is a way to do it.

@ September 6, 2012 1:37 PM in one steam pipe building cant get steam coil for HVAC

If the coil is above the main, you can pipe it like this. Assuming the boiler pressure is 2psi. You'll need 30" in the drip trap for every pound of steam pressure in the system.

Piping

@ September 6, 2012 1:12 PM in one steam pipe building cant get steam coil for HVAC

Where is the steam coil in relation to the steam main? Above, below, by how much much?

Thanks, Jon!

Just goes to show that I do not have an eye for photo quality.

I wouldn't trust him, unless he's willing to change, and do the job right.

Do you have a model number of the existing steam coil? How is/was it connected?

The original topic.

@ September 5, 2012 11:41 PM in Closely spaced tees

Back on track for an answer to the original question.

What defines the pressure in a system? The expansion tank. So, the tank will determine the pressure inside of the closely spaced tees. The tees will not affect any other pressure in the system, so they act as a secondary point of no pressure change. Think of it as a reference/bookmark for the expansion tank. Even if there is no expansion tank, the tees will not have any affect on the system pressure, and thus become the PONPC.

The tank sets pressure. The closely spaced tees will not affect pressure. Different concepts. Similar results.
