Well today we got started on the install. The pipe went together but I noticed a problem after we were done and I wanted to see what you all thought. When we cut the hole through the house we thought we had the holes dead even, after we framed it out, well aparently the holes were off. After we got the pipe installed I noticed the pipe was angled up some, so I put a level on it, and It is pitched up about 1/2 to 3/4 of a inch. It does not look bad, but Im worried about rain getting down inside the pipe, plus Im picky when I do work it has to be perfect or I am not happy. The stove guys are coming to do a inspection, but I wanted to see what you all thought, since I have never tackled a job like this before.
