I have noticed sometimes that when I heat our stove up really hot for the fist burn in the morning there is a weird smell outside. I go out feed livestock and it kind of smells like snakes, you know those little black things kids burn for 4th of July. I just swept the chimney the 1st of December and got pretty much nothing out of it. We are burning dry wood and burning hot fires once a day. Stove is a Kitchen Queen 480 cookstove. Anyone have this before? Anything to worry about? Thanks
