I saw a new 43' ventana today and what confused me was that Newmar routed the exhaust for the hydronic heat out the curbside of the coach. Im not sure I would want to be sitting under my awning breathing in the exhaust from the furnace. Is it diesel fired? Even if it isnt, I find that very strange.

The thought behind that side is they can not exit the exhaust under a slide.

It really isn't a problem. Ours is that way to avoid the full wall slide on the other side. It is never on very long when it comes on and always very quiet. The exhaust is nothing like the exhaust from a diesel engine - it seems to burn more completely to me. jmo mark

A few weeks ago I saw a 2015 London Aire (LA) that had two small exhaust pipes at the front driver's side. I knew that one was for the diesel generator, but was confused about the other. Asked the owner and he said that the second exhaust pipe was for the HydroHot unit. I asked if the HydroHot unit was forward mounted and he said no it was mid coach mounted. The LA was full wall slide out on driver's side.

That seems to be a better design answer by Newmar than routing the HydroHot diesel exhaust to the curb side.

During the past few years Newmar has been moving the Oasis exhaust around on the full wall slide models. What I understand it was due to the interpretation of the RVIA regulations. I think it was before the 2015 models when the exhaust was routed to the passenger side, which was objectionable to some customers. in 2015 they routed the exhaust all the way forward. It was running under the front suspension, which in low clearance situation cause crush the pipes and in my opinion the length of the exhaust could have slightly reduce the efficiency of the furnace. Starting in 2016 they moved the exhaust just in front of the driver side drive wheel. The Oasis is en extremely clean burning and high efficiency system. The exhaust temperature is just warm, there is no tire damage to worry about.

I didn't like mine exiting on the curb side so, just like Dutch Star Don, changed it around to exit the driver side under that big slide. An easy conversion, no new parts needed.

My American Coach just goes straight out in back.

Tiffin and an few others go out the back. I think that or the front is the best solution. No way would I opt for the passenger side.

On my Roadmaster chassis the Aqua-Hot is located mid chassis on the passenger side and exits just behind the tag axle and full wall slide on the driver's side, same side as the gen-set.

Mine is right under the Aqua-hot, midway on the drivers side. Makes for a much shorter exhaust pipe with less chance of issues. This is likely possible because I have 4 slides instead of a full wall slide.

While front or rear pipe routing would probably be best, I believe the mfr. seeks to provide a positive slope to that pipe for moisture reasons. The longer the run, the lower the pipe needs to be.

I noticed in a picture of a DS4310 that the Oasis exhaust is right under the unit itself, but this puts it almost directly under the bunk windows. This is a slight concern due to location. On the DS4369 it seems further back on the FWS closer to the drive axle as stated previously.
