Ben's Fire Pit
This was an old prototype burner installed into an octagonal wooden firepit.
We would not normal recommend building a firepit from wood, or directly on decking, however the pit was a lot larger than the burner, and it had insulation inside to protect the deck. The burner rested on stone blocks, and there was a metal mesh to support the lava rock.
Ok, so Ben forgot about ventilation so this was added later. Amy helped to install the burner and it looks like the whole job was completed in a day.
