The K+ Natural Gas Single Hole Waterless Wok Burner Table is powered by your choice of a 105Mj 24-jet chimney burner or 110Mj 18-jet duck burner, both of which are fitted with flame failure as standard. Lever handle gas controls enable greater regulation of flame setting, which is essential during peak periods. A heavily insulated long skirt unflued cast iron eliminates radiant heat.
