I installed the vent to my pellet new insert starts with 3" adapter --> connected to ( 6" pipe) --> 90 elbow--> 45 elbow --> another 45 elbow --> 24" pipe to outside --> cap.
stove ran perfect but I noticed there is some smoke coming from the pipe vents (from the pipes itself ) the 90 elbow and 45 elbow.. coming from the side of the pipes..
I have no idea why this is happening .. I used 3" double pellet pipes as shows in the pics below and sealed all the joins between pipes.
I used hardwood pellets with this Mt. vernon ..
Any idea why this is happening? and how to fix it? is there special pipe I need to use?
