Cleaning & Maintenance

There is a black oily soot building up on my cooking grids and more importantly on my food, what could cause this?

The black buildup is a sign that your burner is not burning at the correct air/gas mixture. Likely there is a blockage in your venturi tubes or around the air intake holes. There also may be a build up of grease burning on the bottom of the casting. Ensure that the spider guards on the intake holes are clear of debris, and see owners manual for cleaning instructions.
