It showed a hyperlink. The way I attached it shows the picture in the forum page. Might have been a limitation of the mobile phone app.

Needs some help in deciding how to extend the exhaust for my MEP 803A. I have mine installed under roof in a partially enclosed pole barn. In order to vent it outside, It needs to run straight up 4’ and then horizontally over 6’ for a total of a 10’ run. I was planning on supporting it from above with all thread and automotive exhaust hangers and using regular 1-1/4” exhaust tubing.
My question: with a 10’ run, do I need to be concerned with back pressure? I was thinking of using a larger diameter tubing such as up to 2”. I was going to install it with a slight slope away from the generator on the horizontal section to allow for condensation drain. Any thoughts or observations any may have would be greatly appreciated.

increasing size just makes your unit have to push more air. keeping it the same size all the way out creates a vacuum effect which helps pull the exhaust through the line at a good speed.

How partly enclosed are we talking about here? If your missing one wall why even vent it? Or if you really feel the need to vent it just go vertical through B vent for heaters.

Automotive exhaust pipe is prety light gauge stuff and rots out easy i would price out sch40 pipe.

The generator tech at the county mentioned it as soon as he saw the install. "Are you venting it outside?" The guy I bought it from also said something along those lines. The "pole barn" is actually masonary finished in stucco.
