The CG304P/S is a 30-inch, four-burner sealed gas cooktop in Wolf’s Professional trim, identifiable by the heavy knurled knobs used across the pro-style line rather than the smoother knobs on Transitional or Contemporary models. The mechanical spark-ignition system underneath is otherwise the same as Wolf’s other CG cooktops.
Knurled knobs give a firmer, more deliberate grip than smooth ones, but they use the same valve stem connection underneath, so a knob that feels loose or spins without resistance points to the same problem — a worn or disconnected stem — regardless of the knob’s knurled surface. Four burners means describing which specific position is affected speeds up any visit.
