24、 beforecontinuing with testing.4.2 Pilot energy rate is determined, when applicable, for gasbooster heaters.4.3 Flow capacity, energy rate and energy efficiency of thebooster for continuous water flow is determined with thebooster heater inlet water supplied at 110+03 F (43.3+01.7C) and 140+03 F (60

25、.0+01.7 C).4.4 Flow rate, energy rate and energy efficiency of thebooster for continuous water flow at 50% of flow capacity isdetermined with the booster heater inlet water supplied at 110+03 F (43.3+01.7 C) and 140+03 F (60.0+01.7 C).4.5 The preheat energy consumption and time and idle/standby ener

26、gy consumption rate are determined while thebooster heater is operating with the thermostat(s) set at thecalibrated setting(s) to deliver 183 6 3 F at the booster heateroutlet.
