    I wanted to go taller but I was limited by the number of supplies I needed to add to the back, left, right.

The 7-8 round is actually a supply that was not connected yet. 9) 6" rounds off the plenum and since there is no heat upstairs, we are pulling a 14 round off the back and going into the attic to supply 3br and a bath on the 2nd floor. 120yr old farm house with challenging ducting. I would have liked to add return for the upstairs and not used a central return downstairs but it wasn't in his budget

    That looks much better, but , I've got another question, ... How high above the floor of that crawl space is the bottom of that cross-over duct from the floor?

    There was 1 poured pad that is 3" thick originally and he poured a 2nd ext to it so the width would work. We put the box on 2" plastic corners

    Unless we hung the unit on unistrut from the floor joist or set on blocks i am unsure how to hang. The furnace, coil, return, plenum would be 30,34,18,24 ish which would be nearly 9' long and would not fit side to side as the pic looks. It would need to be turned around and much more duct. What is your thought? (I ask in all seriousness as I love options) I was just told about a job today we a doing in a few weeks,, existing oil lowboy, basement height 67" and customer is getting furnace ac with with a total eq height of 64" without duct. Probably going to do the same unless a good horizontal option makes sense

    Kanga,

    I've hung the equipment in 2" x 4" wooden cradles, mounted to the floor joists, that once they were braced off, the platform would easily support me climbing up in it. I've also used channel iron, in the same fashion. The Clermont County Inspectors didn't have one problem with that set up.

    The bulk of the time, that I had a tear out, & then full install, in a basement, such as yours, it did involve more ductwork, in order to tie in to the existing floor registers, & any ductwork that would've fed a S/A &/or R/A to another floor, but, when it was all "Said & Done", we managed to get the equipment to one side of the basement, with the Ductwork installed where it largely wasn't a "Head Banger".

    I did one oil furnace replacement, that was in a stone basement such as this Installation that You did, but I had to pour a pad, cuz' the floor was gravel, install a sump pump, & Reline the stone chimney with a Stainless liner. There was enough height to run the ductwork, & not cause usage of the basement to be prohibitive.

    64" available space between floor & joist bottom? Dang!!!!!!!!!!!!!!!!!!!!! That's a "bow yer head crawl-space"!

    How high is this "Lo-boy"? Has that "Basement" ever flooded? With consideration towards the S/A Plenum being 2" away from Combustibles, what size duct would You have to run?

    What shape is the existing chimney in? Lined? Stone only?

    Could the H.O. be talked in to installing a Counterflow Furnace on the 1st Fl., in a yet to be built room of it's own, with the ductwork in the so called "Basement" then being run throughout??

    We are yanking the fuel oil and going propane so the chimney is not a problem. I believe they have an electric water heater so the chimney will be abandoned.
    I am unsure about basement flooding but looking at the pics it looks like clean concrete and dry at this point.
    We will be reusing the existing supply and return plenums and ducting (maybe adding more return if necessary ad they of course are almost always inadequately sized.
    Putting the unit upstairs seems like a good idea but probably not something that many people would really consider if the basement is otherwise dry. I have only seen some pics but I am going out there later next week to look at it I believe.
