What are the different kinds of burner pans for vent-free gas logs?
There is sheet metal, black pipe and stainless steel. The advantage of the sheet metal is that it is less expensive. Black pipe is heavier than sheet metal and costs a little more. The disadvantage of both is that they can rust through because they have very little rust protection. Stainless steel costs more, but will not corrode or burn through and it will last a lifetime.
