installations having unusual piping and pickup requirements, such as intermittent system operation, extensive piping systems,
etc.
12.1 Ratings and Capacities
• Constructed and hydrostatically tested for maximum
allowable working pressure of 43.5 psig (pounds per
43.5 psig (.30MPa)
square inch gauge)
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.
- Contact Provincial authority having jurisdiction
for installations above 4500 feet (1350 m) above
sea level.
