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.
