Hi, I just restored and installed a Vigilant 1C that was sitting in a dirt basemnt for 20 years. Last night I lit it for the first time. Upon reaching 450-500 degrees the stove exterior started to smoke and filled the house. The smoke was not a wood smell but more like a metal/hot burning smell. It seemed to be coming off at the rear around the baffles. Is this just the Williams polish or stove black burning off? Is this normal for the first burn after some 20 years of sitting? Any advice would be appreciated. Thanks.
