It also has the brick protruding into the door opening which does not make sense.

I split a couple of the insulation board scraps in half to test a theory... My theory is that this arch was engineered to use 1/2" insulation. With the insulation at 1/2" everything fits perfect. Bricks sit inside the top angle iron and the bottom ones sit tight into the bottom and are no longer in the way of the door.

The local store simply claimed this was what it was and that maybe we were being picky. It was suggested that we taper (shave down) the front bricks so they don't get in the way when loading wood...


Does anyone here have a CDL 18x48? Care to give us a hand?


Thanks so much!
I just set up and bricked my CDL 18x60. I found the bricks were tight At the bottom but I had room for 1/2" insulation blanket and bricks to fit on the inside of the cast frame, as on the left hand side of your boiler. Mine came with 1/2 inch insulation blanket, so I assume that is what they are bilt for. They had to be pushed in hard but didn't overhang as you show on the right hand picture.

I have had my first fire and boil, No discoloration only using 1/2" insulation blanket and bricks as of yet.
