Hey guys, I have a 10 year old harman accentra FS. The stove works great but last week my wife shattered the glass hopper lid. (Closed it with a pellet in the way) I replaced it with a new one and a new seal. Now after running a few hours the hopper has some light smoke in it! Is the new seal just too tight, should a little air be allowed to enter so there is a negative flow in the box? If so should I jusy cut a tiny gap in the seal or is something else wrong? Thanks for any help
