furnace replacement

Well, the old furnace has to go. Is replaceing it with a current model going to involve a lot of %&*$?! or is it a pretty simple job? The new furnace is a NT-22 and it is going into a '71 Tradewind. Wiring and gas lines don't seem to be a problem, but the rest could be a bit touchy. Any help would be.....ah......most helpful!

I have never been there but others have, If you use search tool, it will get you plenty of info.

I recall that the biggest problem with furnace exchange is matching the existing duct work to the outlets of the new furnace.

You may have to build some shims to get furnace at just the right position in the void. Some creative duct taping and or sheetmetal work may be in order.

It requires some fabrication, unfortunately.
Once the old furnace is removed, you need to remove the furnace housing from the trailer and then seperate the bottom piece from the furnace housing.
The part you need is the part with the 2 outlets on it, it will end up being a flat box with a hole in the front.
It comes off by chiseling the spot welds. Yes, sharp cold chisel and mallet.
The new furnace then goes on top of the old duct connector, and you will have to fabricate a cover for the front.
It is entirely possible that you also will have to make new holes through the skin for the furnace vent/exhaust.
The burner assembly comes out with the housing still in the trailer. It is easier to remove it as 2 pieces.
If you remove the living room heater vent, then it is easier to pull out the box.
I had never used the furnace in 2 years, so i just removed the defective unit, but saved the plenum box and installed it without a furnace. This way I can always put a furnace back in if necessary. The catalytic heater is usually enough for camping where we like to camp.
There is a factory bulletin on how to replace the furnace. PM me and I will fax it to you if you want. ( Hope I can find it...)
Good Luck
