The upper row of bricks are standard fire bricks except for the front facing brick. It has been cut down for air flow. The bricks can be obtained on
the website or a home improvement store.
The inside row of bricks are identified and counted from the front facing brick that stands on its side. Front brick is #1 brick. #2 is to the left, brick
#3 is in the back and brick #4 is the one on the right. These bricks are all special to their designated placement, and how they are cut and shaped.
The bricks in the bottom of the firebox, if needing replaced, will all have to be replaced at the same time. They are available on the website.
