I have more to do with the ducting but it's hooked up and inside the building. Supply is good to go But I haven't even started the return yet. Got a temp filter set up on the inlet. Want to still come up with a way to shift the suction to an exterior inlet.. I'll have to sleep on it. Putting a Tee in between the building and the unit would have set the unit further out from the back wall. I have an idea that'll use the duct from the Diesel heater.

Big difference in duct size between the old H/P And the Gas pack.

I know a lot about a lot of things BUT I still have a lot to learn.
Life is what you make of it. So, why not make a working machine to make it easier.
