*A
For high altitude installations 5,000 - 10,000 ft. (1500 m - 3000 m), the input for model B2HA 88,100, 150,
311, 352, 530 will have an altitude de-ration of 14% for 5,000 ft. (1500 m) and 29% for 10,000 ft. (3000 m)
average of 2.8% / 1,000 ft. (305 m).
*B
The input for model B2HA 112, 399 at 10,000 ft. (3000 m) will have an input de-rate of 13%.
*C
Net AHRI rating based on piping and pick-up allowance of 1.15.
*D
Tested to AHRI, BTS-2000 Testing Standard Method to Determine Efficiency of Commercial Heating Boilers.
*1
If the gas supply pressure exceeds the maximum gas supply pressure value, a separate gas pressure regulator
must be installed upstream of the heating system.
*2
See "Waterside Flow" starting on page 9 of this manual.
*3
Output based on 180ºF (82ºC), 80ºF (26ºC) system supply/return temperature.
