I have a Winslow PI40 pellet stove that came with the home we just bought and the previous owners said it didn’t work but didn’t know anything about it. It hasn’t ran in over 6 years. I went up top and looked at the pipe and it all looks good and then gave the stove a good cleaning. The ash box in the back was packed and went up the stove pipe about 6 inches. Any advice before I try and fire this thing up? My biggest concern would be a chimney fire as I have had one before with a wood burning stove and it wasn’t a fun experience. I have attached a pic of the pipe from up top for reference.
