NVOY STL 60 Double Doors - Passes Hose Stream Test for North America!
Did you ever see a Hose Stream test according UL 263 or UL10C for the North American market? It's mind blowingÂ
After burning the element during a fire test, the element is removed from the furnace and exposed at the fire side to a fire hose that delivers water at 30 psi from 20 feet away. The glass and element need to withstand that without creating an opening.
