3 inch to 4 inch necessary?

[rideboard147]

I am about to finish off my pellet stove pipe project by extending it more vertical to go through the roof overhang. My question is should I switch over to 4 inch pipe once I go vertical from the cleanout tee? I will have 10 feet vertical, 1 ft horizontal, 1 (45), and 1 tee. That is 14 total equivalent ft once finished. According to my venting pipe graph on my quadra fire manual I can use 3in, but I have seen that you should not use 3in for more then a 10 ft run. I live at just barley over 1000 ft above sea level. Thanks for the help.

The cut-off for the switch to 4" pipe is actually an EVL of 15 or more.....you should be fine with 3", based on the pipe you listed.

Agreed ^^ 15' EVL is fine for Quad's.
