This was advertised as working with natural gas or propane.  It actually doesn't work with natural gas.  I chatted with an agent who told me to order a conversion kit ($79!!!), I ordered it, and it doesn't work with this product.  In fact this product does NOT work with natural gas, and now that I've assembled it (based on the assurance from the customer service rep that I could convert it to gas) I am stuck with it and and an expensive gas line that I installed that I can't use with it.
