I was thinking about trying to replace the water pan rack with a rack of fire bricks. I figured the primary purpose of the water pan was to distribute heat so why not wrap some fire bricks in foil and use those instead? Its such a large surface area, shallow water pan I have to refill every hour and a half, 2 hours. I dont want it to run dry and risk any flames from drippings. I thought using the same surface area of fire bricks would give roughly the same heat distributing effect and not require me to fill a water pan every 2 hours. I would most likely use a smaller but deeper and thicker dish as a water pan if I want any moisture added. I'm using a pit boss 5 series vertical smoker. Has anyone tried anything like these on these pit bosses?
