Question
I have a 7" double wall insulated chimney with a clear 2"  clearnace that comes through my roof for a wood burning stove in my work shop. The chimney extends upwards 7 feetending approx 10" above the peak of my roof at its highest point. If I was to measure from the peak I have approx 9 feet of clearance before I touch the peak to the side. Is it high and far enough both above the peak & away. If not what could happend. Thanks Scott

Answer
Hello Scott, I think you are asking me what the height should be for the top of your wood stove pipe? if so then you must follow the 3', 10' 2' rule...where ever you break the roof line you must go up 3' (min) then go all around in a 10' circle if you do not hit any thing you are goo if you do you must keep going up until you clear every thing then 2' more (min). "what will happen" if you do not? you may not pass a building inspection, you could get wind blown down drafts or you could be fine. Hard to say. most chimney pipes have a min 15' tall height read the instructions for the pipe you installed.
hope this helped
