JennAir’s older Pro-Style gas downdraft cooktops spanned several documented width classes – from the CVG4100 up through the wider CVG4380, alongside the closely related CCG2420 and CCG2423 – all sharing the same sealed-burner, integrated-downdraft design scaled to different cooktop widths. A wider cooktop means more burners sharing one downdraft blower, so our technicians confirm whether a weak-vent complaint is a blower problem or simply a duct run that’s now working harder to pull air across a larger surface.
Key Features
- Wide Pro-Style gas downdraft cooktop, sized larger than JennAir's standard 30" cooktops
- Self-ventilated downdraft system
- Documented across multiple width classes within the same Pro-Style family
