I bought this Furnace to use in my garage, but just never got around to it and its in my way. Its a 90+ Propane. it has a new blower and control board installed, it can be run either standing or laying down(which would work great in an attic).
Model number# GHR26 75,000 BTUs. Have receipts for new parts.
Comes with reducing plenum.
