Propane Furnace Exhaust Fumes Inside Coach
Iíve been looking to buy a 2015 Winniebago Vista 36Y. I live in Northern NJ and couldnít find one locally. I located one at Ray Wakleyís RV Center in North East, PA, some 6 hours away, and liked the unit very much when I saw it. While walking through it, I asked the salesman to turn on the furnace, and when he did, the coach filled with smoke, not so you couldnít see, but enough that we had to turn on the fan and open the windows.
The salesman immediately called their top service guy in, he didnít think it was a big deal, and said new coaches often had coating that had to ďburnĒ off, and as part of their setup, they run all appliances for 6 to 8 hours. It wouldnít be a problem and they would fix it.
The salesman offered that the rig had been on the lot for over a year, and maybe an insect had nested in the exhaust. Itís a 2015 but the MH is new.
Do these explanations sound logical? When he first turned the furnace on, I went outside to feel the exhaust, to see if was getting hot and it was, and the exhaust felt forceful. So Iím not so sure about the insect nest theory. As to coatings needing to be burned off, has anyone ever heard of this. Is this something I should be concerned about? Should unburned coatings be filling the inside of the coach?
The generator was also running really rough, itís an Onan 5500. Iím figuring stale gas, but could the carb be gummed up after a year of not running much and Iím sure no Stabil added.
I like everything else about the rig, the price is right, and I had a really hard time finding a 2015 close by. I put a deposit down, and the dealer is assuring me all will be made right. But I certainly donít want to be in a coach with propane fumes and would like some advice as how to proceed.
