Furnace replacement threads

[CeloNC]

Hello out there. I am about to install a new NT 30SP in my 1970 Sovereign. I know there are several threads on the forum that describe how to do the new install but I can't for the life of me find them. I'd appreciate it if someone out there could steer me in the right direction. It's starting to get chilly here in the Black Mountains of NC! Thanks.

This is what I did:
I salvaged the bottom of the original cabinet and sealed the front end with sheet metal from the old cabinet so I could reuse is as a plenum with the original ductwork. This salvaged plenum has about a 4" opening in the front top surface to line up with the downdraft opening in the new furnace. I had to raise the floor level of the new NT30 SP furnace about 7/8" of an inch and slightly offset to match up with the inlet exhaust vents. I used furring strips. I sealed off the hot air vents on the side of the new furnace with the caps provided with it and aluminum tape. That's about it. I can send a pic of the final installation if you let me know.

I believe one of the threads on this may be by Zeppelenium or Pizza Chop.

Thanks Lumatic. Yes, I'd love to see any pics you have. You can email me at lisabill49@gmail.com or post them on the forum.

Here is where the part of my thread on Henri (my `74 Sov) turns to replacing the original furnace with the one you are talking about, the NT-30SP.

I also mentioned a bunch of other threads at one point, so you should be able to find ways to locate a lot of other threads on the same subject. It is a lot of reading, runs about 50 posts, IIRC.

Lots! of photos.

Take your time, it`s not as obvious as you might think...
