Anybody ever run the generator exhaust through the bus to the roof?
Not us, but I'm sure it's been done. Although ours goes out the curb side, we have an extension tube run it up to the roof if we want to protect our neighbors from fumes.
Several Eagles around have the exhaust for the generator going through the roof 2 x presidents of the Eagles club both ran theirs through the roof ask on the Eagles board www.eaglesinternational.net (http://www.eaglesinternational.net) some one will give you some detail on running it that way
Several things to remember. 1 the exhaust gets hot therefore you need double pipe at least with airflow between the pipes. Convection will do the job. 2 You have to get the exhaust through the living space. Usually routed through a cabinet. 3 use a flapper at the top of the exhaust pipe 4 You have to seal the outer pipe at the roof against the elements 5 make sure the outer pipe can drain without causing damage and 6 it does get the exhaust up and away but not too close to any other air vent.

Right now I just have a 4K, but someday when I grow up I want a 10K or 15K diesel water cooled. What size pipe do you grown-ups use?

1-1/4 id is standard pipe for most of the diesel generators some are smaller depends on how long the the run 1-1/4 id will about cover all
good luck
I ran the exhaust from my 13kw through the roof of my Eagle. I started by exiting through the floor of the bay. I then ran a loop of about 15 feet of exhaust pipe with a muffler, that helps cool the exhaust a little. When the exhaust is within the bus the exhaust pipe is inside of a hot water heater double walled pipe. I used spacers to keep the exhaust pipe centered in the double walled pipe. Before the exhaust pipe was placed in the double walled pipe I wrapped the exhaust pipe with a ceramic heat covering. As the exhaust pipe exits the roof the pipe was turned 90 degrees and faces to the rear. The end of the pipe is also cut at a 45 degree angle that helps any water entering the pipe. It all has worked very well for 9 years and about 600 hours generator time. You can not feel any heat inside the bus when you touch the double walled pipe. It also is very quiet. I will do the same on the 15.

Hi Tikvah,
We ran both the gen and the AquaHot thur the roof.
We did it for quiet and to have the gases up and away.
It goes down thru the bay floor first.
The a 6" electrical conduit is attached at the bay floor and the main floor and the roof.
The 1 1/4" dia exhaust pipe is centered in the conduit then attached to the exit from the gen.
When I'm up on the roof I can look right down the conduit and see the ground.
The gen pipe runs down and then back thru a muffler to be attached to the up pipe.
The AquaHot exhaust runs down the forward to connect to its up pipe.
We have the bus for 12 years and the system has worked out just fine.
