Steam Boiler Header (11 Posts)
Steam Boiler HeaderHello everyone. I am new to this site. It is because of this website
that I was made aware of my steam boiler installation. After reading
several post here I realized my steam boiler was installed without a
header. I bought the book "We got steam" to make sure of what I was
looking at. It even states in the book that today's install guys do not
know how to correctly set up steam boiler piping. This is the letter I
had to send to Peerless in hopes of proving my boiler install is
incorrect. Is it possible for the guys here to tell me if my piping is
bad? Any help is much appreciated. Thank you.
LETTER SENT TO PEERLESS:
How are you. I need your help. I had a boiler installed by a heating
company a few years ago. At the time I had no idea what the correct
boiler piping installation should look like. I recently became aware
that my steam boiler was installed without a header. My radiator steam
vents have always spit water and I could never figure out why. This is
what lead me to trouble shoot my heating system. I downloaded the
manual for the Peerless 63-64 installation and it clearly shows how the
riser and header should look (now that I know). My boiler looks
absolutely nothing like your install manual. I went into one of the
heating company locations and the install manager looked at the photo
and agreed it was wrong. A service man was sent out to look at my
boiler and he agreed it was wrong. An agent for the company called me
later telling me someone would return again to correct the improper
install. Today 5 Dec 2012 the installation guys show up and agree it
was done wrong. They take measurements and promise to return with
materials to start working. Instead I receive a call from the owner of
the company. He told me that he feels that my boiler was installed
correctly and that there would be no work done by his company. The only
way he would agree to do the work is if the Peerless company tells him
that it is done wrong. I have photos of the boiler and piping that I
can send you to show that there is no header. Please advise me on this
installation. If there is a Peerless rep that can come to my home I am
waiting. Thank you. Marlon.
Focusing on the positivesI looked at your pictures and tried to see if there was anything at all in the whole project that could be described as correct. All I can come up with is the following: 1. They used black iron pipe. 2. They used two risers that appear to be the correct diameter. And, unfortunately, that is about it.
What I see that is wrong is as follows:
1. The risers are too short. 2. There is no header. 3. The equalizer is piped wrong. 4. The Hartford loop is piped backwards. 5. Connection to the building main is wrong.
Really, it is baffling how anyone could have made so many errors.Dave in Quad Cities, America

Steam Boiler HeaderThank you Dave and Rod for your information. I suspected as much. However, I never thought I would hear that the Hartford loop was bad too! Wow.
Steam Boiler HeaderHello again. Today I received a call from the heating company
secretary. She informs me that the owner has now decided to make the
correction on the boiler? ???? Figure that one out? The install guys are supposed
to return Saturday morning to re pipe the boiler. I appreciate their turn
around on this matter but I am concerned about the re pipe being done correctly. Just
because they will re pipe doesn't mean it will get re piped the proper way even this time. I could see the header was wrong (now that I know). But I never suspected the equalizer and Hartford loop was bad too. If I complain about that to the install guys I know the owner is going to say screw that guy and they will leave. I need to thread lightly on this. I know the owner does not want to do the work. I shouldn't have to walk on egg shells about getting this done right. But that is how I feel. My question if you can help is how should the equalizer and Hartford loop look on my boiler? Thank you. Marlon.
Steam Boiler HeaderHow are you. Sorry for the delayed update. Your information has helped
a great deal and I appreciate it. The install guys showed up on Saturday. Yes, I had their most experienced steam guy. They have 60
installers and only 4 of them are steam/hot water guys. He agreed that
the piping was wrong and wanted to reinstall to my liking. His only
concern was removing the existing pipes that are connected directly to
the boiler. He was afraid that he might crack the boiler tugging on the
piping. He stated that he knew for certain that his boss was not going
to replace any boiler parts. Only piping. So if the boiler was
damaged it was on me. Yes, he had a very difficult time breaking free
the pipes. I
actually helped pull on the wrenches and even went to my garage and got
my trusted 6 ft long 2 1/2 inch cheater pipe for leverage. The header
was done (photos) but he didn't feel good about trying to redo the
equalizer pipe because it was attached right into the boiler. He did
agree that the equalizer pipe set up should be flipped around but
promised that the water is still sitting in the pipes the same. I
figured that I won enough of the battle and settled for the most
important thing. The header was done. So, this is how it turned out.
What do you think? Keep in mind that I did not realize how much time
has really pasted since I purchased the boiler from the company and they
installed it. 8 years!!!!! It was 8
years ago. My goodness time flies. No wonder the owner had a fit. But,
it was still installed wrong. It took this long for me realize it.
Thanks to the Heating forum and the books I have read. So, hats off to
the heating company for acknowledging the error and addressing it.
Better, but...The header is under size. The IOM says you can use 2"risers if you use 2, but the header should be 2 1/2".1983(?) Peerless G-561-W-S

Boiler Piping ProblemsHi- Sorry to hear that you are having problems. Besides the header, the Hartford loop is wrong. It sort of "reversed" from what it should be. (see attached picture) There is no equalizer pipe and what might be called an equalizer pipe goes directly to the Wet Return with the "reverse" Hartford Loop connecting to the boiler. This is no where near the drawing in the installation manual. The more faults you point out the less likely any one can say that it's okay.
Since the heating company that did the installation buys boilers regularly and you only buy one every 10 to 15 years, the manufacturer, not wanting to upset a good customer, the heating company, will do their best to stay out of any controversy so you need to expect that happening. I'm not saying that Peerless, who are a very good company, will do this, just that you need to understand which way the wind blows so to speak.
I would contact the owner of the company and ask that he personally come out and take a look at the installation "as obviously he isn't able to tell how bad the installation is from pictures and what other are telling him". No business owner wants to go to court and maybe seeing the mess he will come to some sort of compromise.
UnfortunatelyIt Is going to be very hard to get the Original guy back to correct everything
I would suggest you bite the bullet, hire somebody new, just make sure it is done correct this time.
Take your time and get all the correct info which You seem to be doing already.
YikesThis is the same boiler properly piped.This post was edited by an admin on December 5, 2012 7:24 PM.
Boiler RepipeHi- Great news! I‘m glad they decided to take responsibility for it and are going to repipe it properly. There shouldn’t be any problems with this.. Just tell them you want the boiler piped/installed per the instructions in the I& O manual . That’s what you contracted for and that’s what you should get! (And that includes the Hartford Loop piped properly! ) I’ve attached a I&O Manual (Installation & Operating) for the Peerless 63-64 below. The installers may or may not have the I&O manual with them so I would print the manual out so it can be easily referenced by all.
Info on boiler piping - You might want to start by first watching this video on the importance of near boiler piping.
Notes on the I&O Manual
All the piping instructions for a steam boiler are on page 14 and Page 15. Read them over. On Page 14, Figure4.4 “Dual Supply Connections” is how your boiler should be piped. Note the In this drawing note the Hartford Loop conncetion and also the written instructions. On Page 15 Table 4.1 “Steam Supply and Head Pipe Sizing shows the sizes of the boiler piping. Look at the table - Your model is a 63-04 and your using TWO connections (Boiler Risers) The two boiler risers are 2 inch pipe. The Header is 2 ½ inch pipe and while the table states that the Equalizer pipe should be 1 1/4 inches you are better off with 1 ½ inches per Dan’s books.
. If they will do the Equalizer Pipe in 1 ½ pipe fine! If they are going to stick to the instructions at 1 1/4 that’s okay too. (They may have strict instructions from their boss to pipe it exactly per the manual.)
Note Instruction #3 on Page 14 about the header pipe needing to be a minimum of 24 inches above the boiler waterline.
All the piping that carries steam has to be black iron with threaded fittings.
Maybe one of the other Wallies has a picture of a Peerless installation they can post that will give you a better idea of the boiler piping. I’m sure the company is going to send their more experienced guys to do the piping so you are less likely to have problems.
Good Luck! Everything should work out okay!
Pictures of Peerless Near Boiler PipingI recently repiped my Series 61 and posted the pictures.
I'm not a pro myself, but I got a lot of help from the pros here.
I included a "before" photo so you can see the problems I was addressing. It's interesting because, while one could claim that it had a header and swing-arms, the swing-arms were above the header, and the header was under size, so they weren't doing what they were supposed to do.1983(?)
