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
