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.

See “Waterside Flow” starting on page 30 in this manual.
*5
Determine the required size of the expansion tank to be installed in the heating system.
If the integral expansion tank is insufficient, install a suitably sized expansion tank on site.
