Why is my propane heater smoking?

Why does my gas stove turn my pots black?

A dirty stove, or a burner covered in any type of residue, can smoke and leave sooty deposits on pots and pans. Keep the stove top clean from spills, grease and splatters. Make sure the ports or openings on the gas burner are free from dirt and debris in order to have an even flame and to allow proper gas flow.
