Question

Need some help with boiler installation


Hi! I need some help here with installation of a Weil-Mcclain boiler. I bought the WTGO-4 boiler. When I tried to install it, I noticed that one of the hot water outlet is a steel pipe without any thread while the return is threaded inlet. I am completely confused here. Why Weil-Mcclain did not thread the hot water outlet? Is this normal? Can any pros give me some help here? I do not get it why Weil Mcclain did not thread the outlet.
Right now I have no heat for my house. I desperately need some help to get the installation going forward.
Thanks for any help here.

Just screw it out. Its not meant to be a nipple for you to use. You use what ever size nipple/pipe you need for the application the boiler is being installed in.

I tried to screw a nipple in there. It just does not have the bite to go in. Does all boiler come with a unthreaded piping inlet or outlet. Why can Weil-Mcclain just thread the water inlet or out let at the 1st place?

After you remove the pipe another one should screw in without a problem.

Its the way Weil McLain does it.

Other boilers come with no nipple in the tap/port.

Yi..make sure you are using correct pipe nipple..must be NPT (National Pipe Thread) the threades are tapered. and are..available from most plumbing supply stores..Also make sure you are lining it up straight when installing..also put pipe thread compound on the threads before connecting...do you have the right size nipple...check boiler specs/take shipping nipple into store with you to compare...should be easy to connect...if not then, threads on boiler may be damaged/cross threaded.

Sounds like they might be damaged now. Hope he didnt cross thread it. Why do they do this, for a lifting point? I would have expected a hex headed plug.

Probably for a pressure test with a shark bite type coupling huh?

They may use it for a hydrostatic test in the factory. But its not used for anything in the field.

Thanks for all help. With all your suggestions I realized that the piece of steel pipe does not belong there. It must be for the pressure testing at Weil-Mcclain. Somehow Mcclain forgot to take it out or to save time and left there on purpose. I hate Weil Mcclain because I wasted all my time to figure out how to mount the TACO pump onto a piece of pipe which was not supposed to be there. Make you feel you are so stupid.
Anyway thank you all for all your help. Really appreciate it.

The nipple is there to keep the boiler centered within the shipping crate, its a shipping nipple only. If you got stuck on that dilemma how's the rest of the install going?

I was not sure what that piece pipe for. and afraid unscrewing it may damage the body of boiler. The whole boiler manual did not mention that the installer should unscrew that piece pipe and to put a real nipple there, then to install the TACO pump.
I was pretty mad with the fact that Weil-Mcclain wasted my whole weekend to figure out what that piece pipe for. I have to go to NJ to work. I will install the boiler this weekend. I am thinking it may take me half day to put the system to work.
Thanks for the help.
