Air pipe for fire pit.

Piping for gas fire pit want to install a gas fire pit that needs 250 000btu max and needs 3 5 7 w read more.

O gentlemen if you make some holes in the lowest part of the pit s walls the fresh air will enter naturally sucked up by convection as the hot air goes out at the top of the fire. A 2 inch layer of paver base at the perimeter of the fire pit ring.

Concrete blocks on top of the paver base to form the ring. A 1 inch layer of leveling sand. 4 to 6 inches of paver base behind the blocks. The installation for this in ground fire pit has several layers.

If the air holes or air intake vent have been plugged or don t exist at all you may have a hard time getting a fire to burn. I was wondering if there is a difference between drilling many small vent holes 1 25 inch drill bit or making 2 large vent holes busting a few blocks out. I realized how much i need one of these.
