2.7 WATER QUALITY
 Before piping the unit into the system, the system must be thoroughly flushed to remove
sediment, flux, filings, and other foreign matter. The heat exchanger can be damaged by
build-up of corrosion due to sediment.
 The manufacturer cannot be held responsible for any damage caused by incorrect use of
additives in the system.
 Mineral buildup in the heat exchanger reduces heat transfer, overheats the heat exchanger,
and causes failure. Leaks in the heater or piping must be repaired at once. Leakage of boiler
water or HTHW into domestic water side is unsafe and needs to be repaired immediately.
 Air elimination is extremely important from the domestic hot water system. Ensure proper air
vents are installed in the piping systems that are prone to trap air pockets.
 Consider using water hammer arrestors or an expansion tank to dampen the spikes in water
pressure since water hammering can lead to premature failure of the unit.
 Water hardness contributes to the formation of scaling, which impacts the performance of
the heater exchanger and may lead to premature heat exchanger failures. Water softening
may be required if it is high.
 Do NOT use softening agents that use salt, as they can cause corrosion of the heat
exchanger and piping components, instead of telling them not to use artificially softened
water.
 Elevated chloride levels in water accelerate corrosion of the heat exchanger and piping
system materials.
 The pH must always be within the acceptable limits (6.5 to 8.5) of the heat exchanger.
NOTES:
 Consult BRADFORD WHITE factory before using BLP Series units for any other non-
standard applications.
