I'm searching for a mg/mgb boiler manual for Weil Mclain since I am looking for each boilers rating. Does anyone have or know where I could find one online, also does anyone know if having f or pi as suffixes on weil mclain boilers affects its btu/mbu.

    How old is this boiler. Weil McLain has a Discontinued section to look for older stuff. If I'm not mistaken, I think that was the boiler with round corners on the blue Jacket the was replaced by the LG and the LGB with the square corners on the jacket.

    After you make that expensive repair and you still have the same problem, What will you check next?

    I was able to find this on e-Bay if you want to buy that piece of old Literature.

    @Brian S I have some old brochures, catalogs, installation manuals in my office. I notice you are asking about different boilers from last century. We may be able to help if we knew what your goal is.

    LGB is here https://www.weil-mclain.com/products/lgb-commercial-gas-boiler-series-2

    EGH. EG. CGa CG are in the Discontinued section here https://www.weil-mclain.com/products/discontinued-products . Once you get to the Discontinued section there is a search box at the upper right… Put in any boiler you are looking for and you may find more than what is on the list.
