Hi everyone,

I have noticed 2 variations on door shapes. complete arch or arch top with a brick or partial brick vertically as the sides. Is there a performance difference? Height is always mentioned as critical but what about width and shape/ overall area of the opening?

2nd question is the chimney opening size. Is there an ideal ratio of size opening/area to final chimney pipe size? I am doing a 42" oven, 8" chimney pipe.

thanks for any insight.
