*1 Output based on 140ºF (60ºC), 120ºF (49ºC) system supply/return temperature.
*2 Net AHRI rating based on piping and pick-up allowance of 1.15.
*3 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.
*4 See “Waterside Flow” starting on page 8 in this manual.
