So I'm completely new to pellet stoves. I am trying to figure out this Whitfield WP2 Advantage 2. We tried it for the first time last night and it was a struggle the entire time. The stove was puttering around for a while, but I think I was feeding it too many pellets and not getting the fire/heat we desired. So today we took the ash tray and the "grate" out to clean them. Turns out they were filthy. No clue how long since they've been cleaned. Now, in the 2 times I've tried using the stove since, only a few minutes after closing the door, the fire goes out, and smoke starts leaking out around the glass edges, smoking out the room. From what I've read on this site it sounds like something isn't properly sealed. My best guess is the ash tray, but i'm closing it as much as possible and have the "keyhole" turned to the side, locking it shut. Any suggestions are greatly appreciated! Thank you!
