Can the water heater be installed at elevations that are 5,000 or 6,000 feet above sea level?
All Rheem tankless water heaters can be programmed to operate at elevations up to 9,840 feet. For select models optional programming chips are available for elevations greater than 3,280 feet above sea level. One programming chip is available for elevations between 3,280 – 6,560 feet, and a second optional chip is available for elevations between 6,560 – 9840 feet. The chips install on the water heater circuit board (PCB) in a matter of minutes and are available from the Rheem Service Parts Department. This again is an exclusive Rheem feature and is designed to insure proper combustion at these higher altitudes.
