I was wondering if there were any updates on anyone who has tried the different Suburban furnace models? I am searching for a replacement for the non-existent furnace in my 65 Overlander. Currently I'm am trying to figure out the difference (other that size) between the different models, SF-35, SH-35 and NT-34SP. I don't need an exact replacement for whatever furnace was in there originally, because I'll be cutting a new hole in the skin anyway. Thanks!

Patrick

check out the furnace the folks at the VAP's Ambassador Update (look for twin temp). It is probably as expensive as all get out but replaced both the furnace and the hot water heater. It only needed small vents through the floor and not through the side. The idea borrowed Precision Temp's (of RV-500 tankless RV water heater fame) flash heating expertise for a very high efficiency hydronic heating system tapped for a nearly tankless water heater.

Bob,

I am also needing help with my NT-22A. I replaced the Thermocoupler and cleaned the Pilot orfice only to still have the fire blow out when I move the thermostat to start the furnace? The fire starts in the firebox and then blows out after about 20 seconds. I tried to adjust the airtake but it doesnt seam to work? Any pointers or suggestions?

Thanks,
Dan

Leipper,

Thanks for the info, and you are right. The Twin-Temp Jr. is expensive as all get out; seems to retail for $3250 US, (almost as much as I paid for my whole trailer!) (No one said this whole restoration thing was going to be cheap though )

However, I think I'll go with the RV-500 for water heating, and a Suburban Furnace, once I can figure out the differences.

Patrick

Dan with the 75 Argosy,
I had a 73 AS with the same problem where the pilot would blow out as the flame started. I removed the furnace from it's case and turned it upside down. Found water had come thru the vent and rusted holes through the combustion chamber. Tis caused the pressure to change inside the combustion chamber during operation allowing the pilot to blow out. I sent mine back to Suburban in 1982 and they rechambered it for me. Charlie E.

I replaced my ancient Nt24 with a 20s, the job did require building a platform and some depth adjustment for the different vent length but it was not that bad of a job.

I hope the photo uploaded okay.

One more item

I should have added that I used the same vent holes but did have to do a small amount of cutting to get the new configuration. I took the picture just before putting the camel away, though I did stop by during a pheasant hunt last december and ran the furnace it did fine even though it was smaller than what it replaced. I will eventually add a P9000 furnace because it sort of does double duty as a second furnace and a fireplace. That has been put off until next summer. The new ones work fine with a bit of cobbling .

Here is where I bought my replacement Suburban furnace. The price was the best I found. Scroll to the bottom of the page.

Ditto. Smooth transaction, no mark-up on shipping, and an incredible price. What more can you ask for?
