smoking problem solved
April 16, 2015
I just bought and installed a new stove, wow, it looks great and heats up my house in no time and burns less wood than my old stove. The only problem that i had with it was, at first it would smoke very bad when i open the door to put in wood. Idiscovered that the top bricks are supposed to be pulled forward to the front of the stove, at first they were to the back. It works like a charm now.
