Came across a Miller Electric Furnace with AC today, in a manufactured home, that appeared to have a Vent to the roof.
Can anyone explain to me why an electric furnace would need a vent?
The Miller model is E2EB - 023HB and I believe that I’ve found the installation manual for it. http://www.nordyne.com/Literature/708172a.pdf . I can’t see any reference to a vent in the manual. Can anyone explain this? I can’t imagine that the manufacturer of the home would have gone to the trouble of installing a vent for no reason.
