1)
Boiler Input Rate is determined at minimum vent length. The rate will decrease as vent length increases.
2)
Parameter 17 is set to 2,250 at elevations of 2,000 feet and below.
3)
Parameter 17 must be raised to 3,200 at altitudes or elevations of 2,000 feet and above.
• Heating Capacity indicates amount of heat available after subtracting losses up the stack. Most of this heat is available
to heat water. Small portion is heat loss from jacket and boiler surfaces, and it is assumed this heat stays in the
structure.
• Net AHRI Rating represents portion of remaining heat that can be applied to heat radiation or terminal units (i.e.,
finned tube baseboard, cast iron radiators, radiant floor, etc.) Difference between Heating Capacity and Net AHRI
Rating, called piping and pickup allowance, establishes reserve for heating volume of water in the system and
offsetting heat losses from piping.
• Net AHRI Ratings shown are based on piping and pickup factor of 1.15 in accordance with AHRI Standard. Net AHRI
Rating of selected boiler should be greater than or equal to calculated peak heating load (heat loss) for building or
area(s) served by boiler and associated hot water heating systems. Consult manufacturer before selecting boiler for
installations having unusual piping and pickup requirements.
