Customer questions about this product

Is this cooking equipment available in all 50 states?

Due to energy regulations this cooking equipment is not available in Massachusetts, Nevada, New Jersey, New York, Rhode Island, and Washington.

My business is at a high elevation; does this change anything when I order gas cooking equipment?

Many gas equipment manufacturers need to make adjustments to the equipment so it operates correctly at elevations over 2,000 feet. Sometimes we can special order from the manufacturer and have your cooking equipment delivered ready-to-go, but in cases where your unit is in stock and waiting to ship, you’ll need to have a qualified service technician come to your location and alter your unit at the time of installation so that it is compatible with a higher elevation. Contact our Special Orders team prior to placing your order, and we will let you know what will work best for the equipment you are planning to purchase.

Why should I buy a water filter along with this product?

Whether you purchase the suggested water filter through this product page or acquire your compatible water filter elsewhere, be sure to consult the equipment's manual and warranty to understand the importance of correct water filter usage. Using poor quality feed water may void your equipment's warranty. Therefore, it’s important that your water be filtered to the highest quality.
