How are ranges protected when a shelf or salamander broiler is installed above the back of the range?
UL has designed a test for ranges that have shelves installed. Shelves and salamander broilers can obstruct the discharge pattern of a nozzle when it is installed over the center of the range. Therefore, a low proximity nozzle(s) must be used under a salamander or shelf. Or, a specifically listed nozzle designed to protect a range when a shelf is present must be used.
