I got two patio bricks and made a snake path. I line the path with a layer of lump then put my wood chunks in then I top off the snake line with more lump burying the wood chunks. I light three Weber Paraffin cubes at the start of the snake. It takes about 45 minutes to get to temp.
I have a Party model and I have been getting 9 hour + burns at 230 degrees.
++2 on a bad ase weed burner though
