Which burner would be the correct replacement for my old (1981) Weil-McLain Burner (M 710344)? P 465 is another reference # on the face plate. Thanks!

    That's a model 4-65, which means a series 65 boiler having 4 sections. What burner is on it now?

    The burner is just badged Weil McLain. The actual manufacturer should be on the housing. With "M" in the model, I'm thinking Wayne.

    The old burner #(M 710344) Wayne . Air tube length is 6", 80 degree nozzle (with .85 and 60P stamped on it). Should I replace this with AFII- 85 or AFII-150 (Beckett)? The old burner is circa 1981.Head "F" designation on ATC chart is a riddle. Any clarification is appreciated. I'm sure wading through these naive questions and concerns gets annoying to the pros. That said, thank you for any guidance and thanks HVACNUT for your reply!

    That might be a Wayne MS-R burner. Post some pics of the burner and the labels on it to be sure.

    If so, it is still a current model according to their website:

    If not, I'd say a Beckett AF or AFG would be a good choice. You don't need a high-static burner like an AFII on that type of boiler.

    Mr. Steamhead, the burner markings are MP 1160. It appears to resemble Model EASR-S (Wayne). Thx.

    I believe the old burner is a Wayne, model - EASR-S, with MP 1160 punched in the chassis. Circa 1980 (?). Thanks!

    While you have the burner out , check the condition of the combustion chamber/ target wall.

    Thanks, Alan. That is my plan and yet another non-pro learning curve to climb. Your reply is much appreciated! Oh, to be rich and hire a pro while I drink beer and worry about my car. :smile:

    Given the age of the boiler, I'm assuming the lining is asbestos. Another can of worms, perhaps?

    The chamber is not asbestos, but recommended mask & gloves when handling. I don't really think it's wrapped in asbestos under the jacket, as it's probably a late 70's early 80's boiler.

    Also, a standard flange may not fit the bolt pattern exactly. You may have to hold it in place using large washers.
