Most masonry chimneys are 8" square flue but can vary. If you're building a new one, it has to be sized to the connected venting load. Check code manuals or manuf. minimun flue sizes for the equipment you are using.

    1. What size diameter is the standard chimney?
    2. What is the clearance requirement on the inside of the house?

    What size boiler? Clearance depends on manufacture.
