GAS CONNECTIONS
Why Are Gas Connectors Important?
Gas is the lifeblood for many kitchen appliances such as ovens and ranges, bringing the necessary fuel needed for the controlled flame used in order to provide the proper amount of heat needed for cooking and warming. Gas connectors are an often overlooked but nonetheless crucial part of ensuring efficient and safe operation, as they are a safe way
to channel the flow of gas from the source to the appliance while minimizing the risk of potentially harmful leaks. Equally important is knowing which type of gas connector to use and understanding their operation. The checklist below will help you decide which gas connector is right for your establishment and how to minimize any hazardous risks.

Gas Appliance Safety Checklist
• Don’t use residential-grade flexible connectors in commercial kitchens • Ensure that the gas connector is installed in a U shape • Don’t hard-pipe the appliance to the gas supply line • Use a restraining cable for all flexible commercial-grade gas connector installations • The restraining cable must be connected at all times except when the cable and gas connector are disconnected for cleaning Gas Connector Installation Items • Ensure that the gas supply and all appliance control knobs are turned off before making connections • The connector must not be concealed within or run through any wall, floor, or partition • Connectors shall not come into contact with surfaces at temperatures in excess of 230°F, sharp edges, or wiring • The final assembly shall be tested for leaks • An accessible manual shutoff valve must be installed at the outlet of the gas supply piping system upstream of the connector • Connectors are for use only on piping systems having a fuel gas pressure of 0 5 psi or less • Each piece of equipment must have its own shutoff valve
Kitchen Safety and Cleanliness Principles • Appliances must be cleaned
• Appliances must be able to be moved • Appliances need flexible connectors • Flexible gas connectors must be durable • Connectors should be certified by NSF International Flexible Appliance Connectors • Lengths shall not exceed 6 feet • Connectors shall be located in the same room as the appliance • Connectors shall enter a motor-operated appliance with a protected knockout opening • Listed and labeled connectors shall be in accordance with the manufacturer’s installation instructions • Listed and labeled quick-disconnect devices shall be used with listed and labeled appliance connectors • Listed and labeled appliance connectors shall comply with ANSI Z21 69 and be listed for use with foodservice equipment having casters, or equipment that otherwise is subject to movement for cleaning, and other large movable equipment Gas Equipment Connection Compliancy • Utilize a commercial-grade flexible gas connector for all commercial foodservice gas-fired cooking equipment
