Notes:
1.	S = soft water (1 to 7.5 grains hardness)
2.	N = normal water (7.6 to 17 grains hardness)
3.	H = hard water (more than 17 grains hardness)
4. gpm = gallons per minutes, lpm = liters per minute, ft = head loss in feet, m = head loss in meters
5.	Head loss is for heater’s heat exchanger only
