I did try Boston Fincor. They seem to only have manuals for the
current units.
I also looked at some repair places, but did not find any manuals.
Will check Dealers Electric now.

I bought a similar unit from dealers electric several years ago.
I bet they would have one. At the time I bought my unit, these
were discontinued but the manuals were still available online from
boston fincor. Did you try there?
