I am looking for places I can obtain parts for the old Amana HTM Plus
system. I would love to just replace this thing, but it would be
difficult. I live in a 20+ year old condo. The burner unit is on the
roof. The air handler and hot water tank are in the garage, with no
straightforward way to install a flue to the outside. So I'm trying to
locate parts. Anyone got a source?
