Additional Information
Technical Data
*A For high altitude installations 5,000 - 10,000 ft. (1500 m - 3000 m), the input for model B2HA 100, 352 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 Tested to AHRI, BTS-2000 Testing Standard Method to Determine Efficiency of Commercial Heating Boilers.
*1 Output based on 140ºF (60ºC), 120ºF (49ºC) system supply/return temperature.
*2 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.
*3 See “Waterside Flow” on page 30 of this manual.
*4 Net AHRI rating based on piping and pick-up allowance of 1.15.
*5 Output based on 180ºF (82ºC), 80ºF (26ºC) system supply/return temperature.
