gallon
4 Gas pressure required at burner gas train inlet for rated burner input; based on 1,000 Btu per
cubic foot natural gas, specific gravity of 0.60. Refer to burner manual for required pressure.
5 Gross AHRI ratings have been determined under the AHRI provision governing forced draft
boiler-burner units
6 Net AHRI ratings are based on net installed radiation of sufficient quantity for the requirements
of the building
Nothing need be added for normal piping and pick-up
Water ratings are based on a piping and pick-up allowance of 1 15
An additional allowance should be made for gravity hot water systems or for unusual piping and
