Hi everyone. My family just moved to Michigan after 20+ years in Los Angeles, CA and we're having an issue in our new home with our wood burning stove chimney height being a little too short. Luckily I went on the roof and cleaned the downstairs stove's chimney before a big storm knocked out power and we were able to use it for heat during that time. However, when it snows heavy the snow and ice can collect between the exterior metal stove pipe chimney and our brick chimney stack, restricting and clogging the cap. After a big snow storm I tired using the stove again and it backed up inside the house setting off the smoke and co2 alarms! Being at the same level as the brick, the metal chimney also causes soot to collect on the brick. I've included some photos of the scenario.
I would like to extend the existing 8 inch triple wall exterior stove pipe chimney and install a new stainless cap. I know I can fit a piece of slip in single wall 8 inch round x 12 in. long stove pipe and new cap, but I'm afraid water will then collect inside the triple wall pipe. Our existing cap has a skirt that covers the triple wall openings, but I can't seem to find a similar cap. Even if I did, single wall would still leave the openings exposed. Furthermore, I don't think having a single wall stove pipe extension is code on a roof? I can't seem to find any triple wall extensions to get this done.
Does anybody here know the proper way to extend this 8 inch exterior chimney about a foot and where I can find the appropriate parts? Any advice would be greatly appreciated!
