    Kendall,

    All I can find in the Preston Guide is a UGAA-150A. No 150C. The 150A was manufactured between 1977 and 1980.

    I was hoping I wasn't reading the Serial right when I read it as the 22nd week of 1978. After your reply I wander.

    Thanks

    Kendall,

    With Rheem and Ruud, the 'F' indicates the plant it was manufactured at, the '22' indicates the week manufactured, the '78' indicates the year, and the '1558' indicates the sequence number from 0001 up. Thus, that was the 1558th unit manufactured in the 22nd week of 1978 at manufacturing plant F. At least that is how it was explained to me by a Rheem and Ruud factory representative many years ago. At one time I had a list of manufacturing plants and could have told you where plant F was - but that information is long gone from my memory and from my reference material.
