Weil McLain Hot Water Boiler Age

Please help me determine the age of Weil McLain Hot Water Boiler age. the CP # on the jacket is 868524. Thank you.

I think the 6 digit serial numbers are from the 70’s. Call WM at 800-526-6636 for more info.

Thank you Bill for the info. I called Weil McLain. The boiler was made in 1983.

Here’s the new CP Lookup for Weil McLain boilers.

Thank you for the link for boiler age; it came in quite handy on a recent inspection with a disclosed “as 14 years” old boiler that was actually built in 1988 (24 years)
