peerless one or two outputs?

BRIANJ

An indication that your system would use the second riser would be that the Main would have two tappings to receive each of the risers.

peerless one or two outputs

I just had a contractor install a peerless 63-04l steam unit.
On the top of the unit, it seems to have the potential for two steam outputs. The contractor only connected one.
Should two headers have been connected or is it right that there is only one. Much appreciated.Not sure if it matters, but there's 360 sq. feet of radiation.

360 is a ...

relitivly small system...1 output is fine....kpc

thanks, just curious but with the same unit, what type of instalation would require using both outputs? He connected one pipe with two runs coming off of it. Does that matter?
thanks. Why didnt he connect one of the runs to one output and one to the other?

It seems like you don't trust the installer too much. He would be the best one to answer why he piped he that way.

The install seems OK, but I was curious in what circumstances one would use both outputs.

Dick Charland

The use of 2 supplies would be required when the output of the boiler required it, at 360 square feet of steam you have a relatively small system. The boiler you have is a cast iron sectional boiler. As the output increases, the intermediate sections increase (those sections between the front and rear sections). To facilitate things (not practical to manufacture rear sections with no tapping), the front and rear sections have supply tappings available when required. Had the installer put in a 3 section boiler it would have had a supply tapping in the rear section.

Should you have any questions, please feel free to contact me at the E.R. Stephen Co. (800) 649-6789, we are the manufacturer's representative for Peerless in New England or Peerless directly.

The one thing that has not been addressed is did they pipe it full boiler tapping size or bush it down as I see all too often? Do you have the copy of the boiler manual? the piping schedule is in it and that is what determines the correct piping. The installation manual is also available on the Peerless web site.

Could you post some pictures?

jeff_99

the manual specs 2 1/2. I measured the pipe, coming vertically directly out of the unit and it measures 2 3/8.
Im just suspicious of everything by nature and just seeing if it was done right.

Scott Kneeland

Jeff,
Iron pipe is measured inside diameter. If yours is 2-3/8 aprox O.D. it is 2" pipe. this is not piped correctly. I know I may get some flak on this but most companies can't thread over 2" pipe so tey cheat it. If the installation manual says 2 1/2" it would about 2 3/4 O.D. Using the correct pipe size and piping it to spec is what seperates the people who just put in equipment from the professional installers.I know that these are not kind words but as I've said "this ain't a hobby"

Thanks Scott. Why do you say some people may give you flak about your comment?

jeff_99

There are two tappings, but they connected them to one of the risers. they sealed the second riser. I was told by the peerless rep that with the size of the radiation, 360 sq. feet, that tapping into only one riser is fine.

Noel

Jeff, that was bad advice, above.

If you have two risers to connect to the system, they BOTH will connect to your HEADER pipe. The next tappings, in order on the header, will be the tees that each connect to the piping in the building, each pipe connecting to a different tee on the header. The last connection on your header will be the equalizer pipe that steers ALL of the water that is thrown up into the risers down to the Hartford Loop connection, below the water line. This will be shown in the instrucion manual.

There will NEVER be a modern residential boiler that will connect each riser to a single system pipe without a header and an equalizer to return the water to the boiler, like the old boilers used to do.

Thanks Noel.
Just want to make sure Im talking apples and apples.
There are two (potential) lines that come out of the boiler.
One is sealed and the other is the one they hooked up.
I was curious as to why they wouldnt connect both, since I see two separtate lines going from the one line they did go into.seem more knocking than my old 80 yr old system too.

Noel

Look around my website, here.

It certainly contains less info than THIS site, but some of the pictures in some of the articles might add some insight to what you've learned here.

Thats awesome. thanks. Ill have to read it thoroughly when I can break away from work. I looked at the header and it has no pitch. Shouldnt it have a pitch toward the loop so it can drain properly?

Noel

As long as it doesn't pitch backwards

It won't be an issue. The air, first, and the water and steam next, all blow through there at over 30 miles per hour. The wet pipes in a level header won't be an issue.

finally a picture of the install.
