Dormont products here include the 0241420, a 3/4 inch by 36 inch moveable-grade gas connection kit. It connects gas appliances that are moved for cleaning, such as commercial cooking equipment, to the building gas supply.
Choose the connector diameter and length based on the appliance BTU input and the distance to the gas outlet, keeping the hose free of tight bends when the appliance is in service position. Check whether a restraining cable and quick-disconnect are required by code for casters or moveable equipment, and leak test every joint after installation.
