Accordingly to NYC boiler code at what size and when does the flue of a atmospheric or power vented commercial boiler have to be welded?

Paul what kinda of boiler cast iron or steel? Cast iron minimum 22 gauge glue pipe and can be screwed together
Steel boilers welded. You can find that info on that info in the mechanical code and on the department of boiler/ boiler divisions website
