So while redoing my install, I disconnected the Exhaust started tube from the stove motor housing. Enviro designed a one bolt, easy to screw system. However, by looking at the old gasket in between the two pieces I could see ash marks all the way to the outside of the gasket. Also, the gasket was really compressed by the bolt side, but on the opposite side it was much thicker and less compressed, making me think that side does not get enough tension to make a tight fit. As you can see from the motor housing picture, the Exhaust tube is supposed to jam itself on the opposite side of the bolt system and create enough pressure to seal it. Those folded lips of metal are supposed to hold it.
but playing around with it while i have it apart, there is slack even when i tighten the bolt all the way down. Granted, it was without the gasket on, but it looks like more slack than what a gasket can fill. Even then, it should be a little tighter. Enviro should just add two more bolts to make more secure.
To fix I am thinking of creating some kind of bolt clamp to tighten that end, or fold those flaps a little tighter, though I am not sure if I can do it well enough.
Secondly, the Exhaust starter tube is made of two pieces, a tube and a flange that is welded on. As you can see, there are 4 spot welds only. though, the flange seems pretty tightly compressed into the tube, on mine there was some warping and I could even see a little day light in between the flange and tube. The point here is that this tube sees a lot of stress being the connection point, so a uniform weld around the tube and flange would prevent this from failing, especially with exhaust fumes coming out. I ended up carefully hammering the gap to close and then siliconed up.
Let's see how it works when I am finished.
Any ideas from the M55 owners or anyone else, would be greatly appreciated.
