Re: vent size for a 36" internal tuscan? I am not finding in the plans the dimensions for the area I am trying to describe. Sizes in plans are refering to castable transition itself from the brick vent not the size of the brick vent opening itself. Not as far as I can tell anyway. I am hopeing there is a proven and idea number here for me. It seems like this size should be very important and I dont want to miss this. So far a have built my 36" internal to specs in plans but I seem to be missing this important mesurement for the brick vent archway opening........wayne |
