I've been reading on here for months the heartaches first year burners go through thinking all the while i was ahead of the game. Less than one week in to the season and i'm already getting frustrated. Get the stove top up to around 550, seems like decent secondary action, then i go outside and look at the chimney to see the smoke just pouring out. Wood isn't sizzling, but it is some punky junk i'm trying to get rid of in the shoulder season. Hopefully the main supply burns cleaner. If not its going to be a frustrating winter.
