Finished up the exhaust and air supply today
Put the termination on the exterior of the building. It has the intake on the bottom and it's screened to prevent bugs or birds from getting it. The exhaust has the necessary accelerator built into the opening.
And hooked up condensation trap but still don't know
where it's going to drain to right now except for a pan.
Used the foil tape to seal the main trunk to the furnace so that trunk is sealed now. Well except for the 2x4 hole at the end of the line that will be closed up after I put the registers into the ducting.
I spun up all the black pipe as much as possible without breaking into the gas line. Now I'm kinda stuck because I can't get the 4x8 sheets of polyiso board I need to finish up the in floor ducting. Apparently a really really bad mistake on my part in not getting enough when it actually existed.
