12.1
Ratings and Capacities
• Constructed and hydrostatically tested for maximum
allowable working pressure of 43.5 psig (pounds per
square inch gauge)
43.5 psig (.30MPa)
in accordance
with ASME Boiler and Pressure Vessel Code, Section IV,
Rules for Construction of Heating Boilers.
• USA - Input rates are derated 4% for each 1000 ft (300m)
above sea level, beyond 2000 ft (600m).
• CANADA - Ratings in table 13 used for elevations up to 2000
ft (600m) above sea level
- For elevations between 2000 ft (600m) and 4500
ft (1350m), derate 10% using high altitude kit.
