Table 6B Circulator Recommendations for Temperature Rise Applications_20°, 25°, 30, and 35°_Boiler Only
The temperature rise provided by a pump/model combination will decrease by 3% per 1000 feet of elevation.
NOTICE
Pump sizing and flow requirements are based on 20 feet of piping, 4 - 90° elbows, and 2 - fully ported ball
