12.1 Ratings and Capacities
• Constructed and hydrostatically tested for maximum
allowable working pressure of 50 psig (pounds per
square inch gauge) (345 kPa) in accordance with ASME
Boiler and Pressure Vessel Code, Section IV, Rules for
Construction of Heating Boilers.
• Ratings used for elevations up to 2000 ft (600m) above
sea level.
• For elevations above 2000 ft. (600m) reduce input rate
4% for each 1000 ft (300m) above sea level.
