I purchased a house with breckwell pellet stove insert but is leak smoke all the time. If i let it burn for couple hour it will smell burn for whole house. I vacuum and clean the exhaust pipe, its still smoke. Than i pull the top panel and look for smoke when first start and i find the stove leak smoke at the all joint especially on the connection pipe at the exhaust fan and one more connection between the 90 joint. I try to reseal the pipe with silicone but it still leak less. I am frustrated with the stove installation. Notice the pipe don't fit right at all the pipe. If u push the pipe down to their lock position. The stove sit little low to the per drill exhaust pipe. I and that pipe is not total center with pipe (offset) slightly. I have to pull the pipe slightly apart to install them and its a pain since I have almost no space to work. Sorry for the painful explanation. My question is that can I use stainless steel exhaust pipe for car as alternative. I can cut and bent what i need to fit and use me high temp exhaust wrap that rated 1500 degree and clamp to seal and insulated the pipe. I think its should be ok. Opinion
