Suburban furnace

[Tony S]

Hi Folk

I was told it is best to use all 4 vents outlets instead of 3 that was recommend, as minimum, for my new Suburban NT 30. Was that suggestion valid and how much does it matter. My trailer is 25' TW if that matters.

Any advise would be appreciated.

It really depends on how restrictive the 3 vents are. Usually one dumps right into the living area and two or more hoses go to the rear of the trailer. That one that is in the living area probably flows as much as the other two combined. The rear of my trailer is cold compared to the front. I would like to add another hose just to even up the temperature a little. There is also a little one going under the floor.

These things have a flow interlock. If the flow is not sufficient they will shut down or not light in the first place.

So it sounds like I am in fact better off doing the 4. I guess at this stage of the renovation I am looking for short cuts. I have one dumping into the living area, one going to the bathroom one by the birth and living I have designed things so I can run one to the other side of the trailer by the door. That one might even things out or blow us out of the living area. It is a 73 TW if I didn't say.

Thanks Perryg114 for the imput. You have help me before.

Hi Tony...I'm dealing with the same issue in our "74" Tradewind. Do you have ductwork that runs back under the galley and under one of your bunks? Is there also the rectangular cutout going under the floor? Here is what ours looks like...at least at this point until it gets replaced. Was your original furnace an NT-22?
Thanks!


By the way...the wrench on the furnace came from Airstream...wonder if they are still looking for it? It was wedged behind the furnace...

Hi Bob

That looks so familiar. I thought mine was the NT30 I hope I didn't buy too big.

My duct work was run like yours. Actual all the set up I see was the about the same. By the way your floor looks to be in clean shape. Nice keep sake that wrench.

Below are a few pics of the old furnace and the new that I am working on. It is getting very crowded running ducts not to mention covering the runs. I am running or contemplating a run around the back of the front gaucho to the door side. I am using flex duct. No pics

Tony nice job installing the furnace and cleaning up the "rats nest" of plumbing under the sink. I'm going to pex everything. Did you close off the access to the belly pan and run your fill line through the "new floor"? Like your idea of running flexible duct line to the other side. What did you put down for flooring? Did you use mahogany for your galley face? Thanks!

Thanks for the complement.

Sapale face ala African Mahogany-- one of the may species under that title.
quarter sawn ie ribbon. I actually faced ribbon with better ribbon for most of it. Kind of crazy but....

I am going to run pex next. May be a bit of an upgraded rat's nest when I install pex.

I used full 3/4" Fir marine plywood for the floor. Full spread penetrating epoxy and then laid Marmoleum over it. Epoxied edges and some inches in underside
