Hello again, Today I had my chimmney installed and for some reason my installer changed the setup. Instead of using wall brackets that came further out so he could go straight up passed the gutter. He did a 15° offset passed the gutter. Well I guess it's not the end of the world but I hope it works well. I didn't like how he put 2 x 4 blocks to put the wall brackets to the siding. He said it will hold up better Plus come off the siding better for the offset. Oh well. Anyway he put selkirk sure-temp double insulated pipe. He has a 4 foot horizontal run from the wall thimble to the tee. There is a 1 inch rise as is described in the stove manual to do. He said with this type of locking pipe it's hard to get a big rise out of it. But he was able to get an inch rise which it says 1/4 inch rise for every foot in the manual. From the top of the tee to the cap is 20ft I think that will give me good draft. I have to wait for him to install the stove because he had the wrong size double black pipe from the stove to the 90° elbow. With the pipe the way it is i put a Lit match in front of the pipe opening and it sucked in the flame and blew out the match. I hear a swooshing sound and has a good strong draft. I just hope it stays that way.
