The cooking range uses linear valves for improved operation and adjustment capability, including the ability to simmer. Unlike most competitive models, the burners can easily adjust from a low simmer to a full burn. In addition, the High-Output 9,000 BTU front burner and two enhanced 6,500 rear burners help cook food faster! The one-piece porcelain grate construction gives more than adequate surface area for pots and pans. The larger diameter wire provides strength and the grate is easy to remove for cleaning, yet fits snugly in the cushioned grommets to help eliminate excessive rattling during travel. The top burner areas are designed with a deep well that helps contain messy spills. The cooktop is fastened securely with special clips to prevent excessive rattling during travel. For easy access to clean below the top, simply lift the top up and out of the way. The top can be quickly snapped back into place.
