WM Burner tubers

[Deleted User]

Josh, I agree with your line of think, I was just reaching for an ez fix. This is an old boiler and the supply house is having a hard time finding the burner tubes.
The service guy I called for an unrealted problem didn't even notice the tubes when he removed them, I had to point out the condition of the tubes to him. The first thing he said when I told him I had a Weil-Mclain is, "I sorry for you" When I asked if he does a lot of work on boilers, "boilers, furnace, same thing, one has a blower and you have a pump & water" Later in conversation, he admitted he has never installed a boiler in his life.
Boy I have a lot of confindance in the service guy!!!

I am in schorched air country!!!

My father used to do plumbing/heating, and I use to be his grunt. I knew more about this boiler that this guy.
But thanks for your imput.

WM burner tubes

I have a WM HE series 2 nat. gas boiler with 10 burner tubes. In this years cleaning I have noticed that at the end of majority of the tubes a small rust threw spot, about the size of a pencil eraser, no larger. These are just plain steel, not SS. Can this be brased to fill in the hole or would something like JB Weld work, with the heat?
I don't see a large flame comming out of the hole, but it dosen't look like the hole would be good. And for the most part the flame is pretty even.
If I had to spring for a new set of tubes, what would be a ball park cost? The tube that holds the pilot is ok.

Fred, one thing is for sure. You can't leave the tubes the way they are.

Second, JB Weld will NOT work in this situation. It doesn't belong anywhere on a Boiler or Hydronic heatin system.

I also wouldn't recommend brazing. You could warp the tube and cause poor combustion.

I am not sure what the cost of new tubes are for that particular model but my advice is to pay up on this one. Go to Weil-Mclains website and find your local rep. Your rep can tell you who you might buy the tubes from locally.

Burner Tubes

You may also want to check the Bracket in the back of the burner chamber that the tubes sit on for rust and deterioration. I had a major horro story this week. Walked into a basement of a house that we were installing a new Buderus wall hung boiler for the hydroair system we were installing. When i got into the basement it smelled like flue gas. as I crossed the basement the steam boiler kicked on and sounded like a flame thrower. I pulled the front panel off to find the whole front compartment filled with flame. After shutting it off I found 2 burner tubes droped on the floor and the entire back hanger and one end of a burner tube had rusted away. So DO NOT mess around with trying to fix a burner tube it is not worth it. The basement of this house was filled with carbon monoxide which could have killed everyone in the house.
