Most furnaces I've seen in this forum are the Suburban 'NT' type, which are taller. I have the same question: has anyone installed one of these low profile 'SF' style furnaces, and are they happy with them? Thanks for your input.
Smily:
More specifically, and not meaning to be obnoxious, does anyone have experience with Suburban 'SF' low profile furnace? Not looking for rehash of pilot lighting problems, bypass hoses, catalytic heaters, or gas valve problems. Just want to know if anyone has tried a Suburban ST furnace?
The only real problem with a furnace replacement is that of matching the holes in the skin to the ports on the new furnace. A secondary problem is the ductwork.
For the usual NT30 replacement of the mid seventies 32 unit, you have to slide the old furnace out of its case, remove the case from the plenum below it, and then use a spacer to lift the NT30 an inch or two to line up the exterior ports with the holes. You might also need to open up the bottom vent to the plenum and block off the side vents on the furnace. The spacer usually used is a layer or two of 3/4 plywood with an apperature cut for the furnace to plenum air flow.
For the low profile units, hooking up the existing ductwork is likely to be interesting. I don't know if they have vents on the bottom.
BTW, I found a new NT30 for $350 at a surplus place. So look around and you might be able to save a hundred or two from retail sale. (might start with Ebay)
look on ebay for truck and RV supply. replaced mine and it was about $100 less than camping world. and it was shipped from suburban. pays to look around. camping world normally has the best price when on sale.
my excella 500 had a nt 30 furnace. the airstream don't let you switch as you have to match up on the vent holes. or you wind up with a mess.

My furnace is in good shape but I need the blower motor.

Replacing an original NT Suburban with its modern equivalent isn't hard, but there are some minor fit issues that have been mentioned already. All of the current NT furnaces are the same physical size, which simplifies things. As I mentioned in that other thread, watch out for new vs. original furnace ratings when replacing.
I replaced my Suburban NT with one of the low-profile units. It was a lot of work, but worth it to me because I wanted to relocate the furnace. My two goals were to improve some of the very inadequate original ducting and use the limited storage space in my Argosy MH more efficiently. The NT took up a big volume that's now dedicated to a huge drawer, while the new low-profile unit fit into a spot that was mostly wasted before.
BTW, I still have an almost-new NT-24SP for sale at a very attractive price.

Hi Bob
I am interested in your furnace, I need only the motor,if you think the application is same , would like to purchase your furnace.
thanks, Ken1s@yahoo.com
Margo, I tried to email you but the system tells me your email is blocked.
My Suburban NT-24SP is still available for $225 plus shipping.
I have scanned the installation sketch from the furnace manual and will email it to anyone who is interested. It shows the modifications you have to make to use the modern Suburban furnace. The file is about 1 MB.
