Does anyone have any info on WM's mgb series gas boiler? Looking for ratings (especially the mgb-5), and when it was discontinued. Thanks in advance.

    From an old W-M boiler CD-ROM I have:

    The MGB-5 Series 1 was rated 680 MBH input and 544 MBH Gross Output, and was made between April 1973 and January 1984.

    The MGB-5 Series 2 was made between January 1984 and December 1985. It was rated 680 MBH input and 510 MBH Gross Output.

    Not sure why the Gross rating was lowered, but there it is.
