Boiler Water Chemistry; Freeze Protection Fluids; Part 2 - Before You Start; What's In The Box - Westinghouse WBR080 Series Installation, Start-Up And Maintenance Instructions


Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system may be
damaged, possibly resulting in substantial property damage.

Do not use "homemade cures" or "boiler patent medicines". Substantial
property damage, damage to boiler, and/or serious personal injury may
result.

Continual fresh make-up water will reduce boiler life. Mineral buildup in
the heat exchanger reduces heat transfer, overheats the stainless steel
heat exchanger, and causes failure. Addition of oxygen from make-up
water can cause internal corrosion in system components. Leaks in the
boiler or piping must be repaired at once.
F. BOILER WATER CHEMISTRY

Sodium less than 20mGL.

Water pH between 6 and 8
o
Maintain water pH between 6 and 8. Check with litmus paper or
have it chemically analyzed by water treatment company.
o
If the pH differs from above, consult local water treatment
company for treatment needed.

Hardness less than 7 grains
o
Consult local water treatment companies for unusually hard
water areas (above 7 grains hardness).

Chlorine concentration less than 100 ppm
o
Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm.
o
Do not connect the boiler to directly heat swimming pool or spa water.
o
Do not fill boiler or operate with water containing chlorine in excess of 100 ppm.
NOTE: It is recommended to clean heat exchanger at least once a year to prevent lime scale buildup. To clean the heat exchanger,
follow the maintenance procedure in Part 13, Section B of this manual.

G. FREEZE PROTECTION FLUIDS
NEVER use automotive or standard glycol antifreeze, or ethylene glycol made for hydronic systems, with this boiler. Use only inhibited
propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and
seals used in hydronic systems.
Consider boiler piping and installation when determining boiler location.
NOTE: Damages resulting from incorrect installation or from use of products not approved by Westinghouse ARE NOT covered by
warranty.
