K. Water Chemistry Requirements*
Chemical imbalance of the water supply may affect efficiency
and cause severe damage to the boiler and associated
equipment. Westinghouse recommends having water quality
professionally analyzed to determine whether it is necessary to
install a water softener. It is important that the water chemistry
on both the domestic hot water and central heating sides are
checked before installing the boiler, as water quality will affect
the reliability of the system. Failure of a boiler due to lime scale
build-up, low pH, or other chemical imbalance IS NOT covered
by the warranty.
• Sodium less than 20 mGL
• Water pH between 6.0 and 8.0
• Maintain water pH between 6.0 and 8.0. Check with
litmus paper or have it chemically analyzed by water
treatment company.
• If the pH differs from above, consult local water
treatment for treatment needed.
• Hardness less than 7 grains
• Consult local water treatment companies for unusually
hard water areas (above 7 grains hardness).
• Chlorine concentration less than 100 ppm
• Using chlorinated fresh water should be acceptable as
levels are typically less than 5 ppm.
• Do not connect the boiler to directly heat swimming
pool or spa water.
• Do not fill boiler or operate with water containing
chlorine in excess of 100 ppm.
*NOTE: It is recommended to clean the heat exchanger at
least once a year to prevent lime scale buildup. To clean the
heat exchanger, follow the maintenance procedure in this
manual.
Hardness: Less than 7 grains
Chloride levels: Less than 100 ppm
pH levels: 6 - 8
Conductivity: Less than 400 uS/cm at 25
