    I have zero knowledge of wood stoves, but having said that, the code does not mix make-up air for fireplaces, wood stoves, whole house or ERVs and HRVs with kitchen make-up air. Its two completely different issues and codes.
    2015 IRC M1503.4 Makeup Air Required: Exhaust hood systems capable of exhausting in excess of 400 cubic feet per minute (0.19 m3/s) shall be mechanically or naturally provided with makeup air at a rate approximately equal to the exhaust air rate.
    All range manufacturers should provide the minimum required exhaust hood cfm, which in turn you must apply M1503.4.
    Here is some reading that may interest you:
