My Mods: Shortened and Raised Generator Exhaust Pipe
The generator exhaust pipe on my coach was very long and very low. The reason for the length was the desire to get the end of the pipe past the bedroom slide. The reason for the low ground clearance was likely two-fold. My coach was lowered by about 2" as a result of my MORryde Independent Suspension install (this lowering was one of my goals). The other reason was that the factory simply hung it too low in my opinion.
My primary motivation for reworking this pipe is that with a 7 degree upward slope on my driveway, the pipe scraped my concrete driveway. We tried to protect the concrete with thin paneling strips but it still got away from us a couple of times and the pipe end scraped and the u-bolt ends and the bracket bolts scraped
Working with Heartland and with them consulting the most current code, it turns out that my generator exhaust pipe needs to have a vertical clearance of 36" to the bottom of the bedroom slide. Also, it needs to have a horizontal clearance of 36" to the center of the LP regulator (in the LP tank cabinet). So it was installed within code but perhaps a bit overdone. Apparently, it does not need to go past the end of the bedroom slide. Mine is now at about the center. That said we do not sleep with the generator running.
I ended up moving relocating the end of the pipe to about 38" rearward of the center of the LP regulator. I ended up reworking the mounts to move the pipe about 2" higher and still have about 2" clearance to the coruplast when it makes the turn to go over to the generator.
Before - you can see the gen pipe is lower than the sewer outlet.
The sewer outlet cleared the driveway/garage floor transition by maybe an inch.
After - Tighter to the frame and about 3 feet shorter.
Here you can see down the side of the coach.
The gen pipe end sticks past the side of the j-wrap by about 2".
Looks like the pipe comes out at about the mid point of my storage door.
The Change-Over/Regulator is just to the right of center
of the LP tank. The gen pipe outlet is about 38" horizontally from the regulator.
