WATER QUALITY REQUIREMENTS

Incoming water in excess of 3.0 grains of hardness per gallon (GPG) (.75 grains
of hardness per liter) must be treated and softened before being supplied to
water heater(s). Water containing over 3.0 GPG (.75 GPL) will decrease the
efficiency and reduce the operating life of the unit.
