Age please?

Weil-McLain gas fired boiler ser #CP1046540

Weil McLain can be tough to figure out. I suggest you call them directly at: 800-526-6636 They have always been very helpful in the past.

(219) 879-5661 or (866) 783-9276 and ask for Technical Services

Thanks but I googled Weil McLain CP look-up and their website confirmed age of unit.

1984 I believe.

Sounds about right - Weil McLain switched from 6 to 7 digit serial numbers in the mid 80s.
