Flex Pipe vent question

[LuvMyPellets]

I was over at a friends the other day and he showed me his installation. I told him I was not sure it was up to snuff on code. Out of the back of the stove he has about a 12" piece of stainless flex and that runs into an adapter(flex to pipe) and then regular 3" pellet pipe out the wall and up. Don't get me wrong, I like it. It got rid of a 45 and a 90 and now is just a gentle bend which is what he was trying to do. The flex is wrapped in fireproof insulation and then with the heatproof tape-all of which is behind the stove and not even visible. I just question if you are legally permitted to do that..

Legal. Probably.
Good practice. No.
Without a "T" cleanout, ash will build up in the pipe.

is the flex listed as pl vent? that's really what will mater

 

[LuvMyPellets]

The flex is the same thing they use when venting up an existing chimney so I am guessing it is PL.

 

[hwdemers]

then technically if appropriate adapters and sealants are used and clearances are maintained ,it would have to be code unless the manual specifically says something in reference to approval only with certain manufactures venting

btw im not advocating the installation practice, and agree with michael6268
