I've had my PG 500 since May and have went thru 5 bags of pellets. I really gets used more than my FEC 100. A couple of weeks ago, while trying to remove the offset side grate, I noticed the steel divider wall, which separates the direct and offset side is badly warped, obviously from the heat. It's really difficult to get the offset-side grate back in without using a screwdriver to pry the wall over. Has anyone else experience this? Maybe I'll call cookshack. Works fine otherwise. I do get some smoke coming out of the pellet hopper.
