Atmospheric heaters:
Rated inputs are suitable for up to 2,000 feet elevation. For elevations above 2000 feet, reduce input 4% for
each 1,000 feet above sea level, as high elevation reduces combustion performance.
Low NOx heaters:
Rated inputs are suitable for up to 5,000 feet elevation. For elevations above 5000 feet, consult the factory.
