A question about makeup air
I don't know this for sure, because I haven't gotten far enough in the process, but I'm assuming that if I get a 600 CFM island range hood for my gas cooktop, I'll be required to include a system for makeup air. My question is this -- I presently have a (useless) telescoping downdraft exhaust system, which I'll be removing. Can the existing downdraft ductwork somehow be retrofitted to accommodate a makeup air system? Thanks!
