Does *THIS* "SHALL" mean anything to you?

From the IRC. (bold and underlining are mine).

- M1307.1 General. Installation of appliances shall conform to the conditions of their listing and label and the manufacturer’s installation instructions. The manufacturer’s operating and installation instructions shall remain attached to the appliance.


OK then, is a vent considered an appliance; I think not.


Sorry Jerry, you're making this up as you go.......
