The Rheem SP20174AB High Altitude Orifice Kit is for LP gas water heaters that work at elevations from seven thousand one to eight thousand feet. This kit modifies the fuel-to-air ratio, ensuring the right combustion in high-altitude settings. It helps achieve the best combustion efficiency and guarantees safe operations by modifying the gas flow to suit the thinner air found at high altitudes.
