The Suburban Automatic Changeover Regulator automatically switches from empty service cylinder to full reserve cylinder, ensuring continuous gas flow to appliances. A highly visible full/empty indicator signals refill. This unique indicator is also visible from the top when viewed through propane tank cover lid, eliminating the need to remove the entire propane tank cover to view which cylinder is full or empty. Adjustable pressure setting and high temperature resistant diaphragm. This kit includes already assembled mounting bracket for ease of installation and the plastic vent cover required by RVIA. Safety features include built-in back check valve that allows empty cylinder removal and refill as reserve cylinder remains operational. An excess flow device ensures protection with all hose connections. Limits gas flow in the event of hose rupture or accidental disconnection. Overpressure Protection Device limits environmental propane release in case of regulator malfunction to a value less than 2 psi, significantly lower than that mandated by UL standard 144.• Automatically switches from empty service cylinder to full reserve cylinder• Ensures continuous gas flow to appliances• Kit includes mounting bracket and plastic cap cover• Highly visible full/empty indicator signals need for refill• Built-in back check valve allows empty cylinder removal and refill as reserve cylinder remains operational• Adjustable pressure setting• 160, 000 BTU/hour• Inlets: Two 1/4" inverted flare• Outlet: 3/8" female pipe thread• UL listed• Dimensions: 10.938" x 6.875" x 4.563" Highly visible full/empty indicator signals refill Unique indicator is visible from the top eliminating need to remove cover Adjustable pressure setting & high temperature resistant diaphragm
