To drain. Confirm slope. Slope the condensate hose and drain piping toward the drain and
secure to prevent accidental dis-assembly.
Danger
The water in the condensate neutralizer can cause severe burns to the skin. Wear
protective gloves and eye wear when servicing the condensate neutralizer.

Warning
Water quality has a significant impact on the lifetime and performance of a boiler's heat
exchanger.
Improperly prepared water in a heating circuit may cause damage to the heat exchanger
through fouling or corrosion. Repeated or uncontrolled water fills will increase the potential
for damage.
High levels of dissolved solids or minerals may precipitate out of the fluid onto the hottest
part of the heat exchanger, impairing heat transfer and resulting in overheating and
premature failure. The amount of solids that may form on the heat exchanger will depend on
the degree of hardness and the total water volume in the system. A high water volume
system with a low hardness count may cause as much damage as a system with less
volume and higher hardness, so it is recommended to treat water so as to remove all
dissolved solids. Other water chemistry allowable limits are as follows:
Acidity pH is to be between 6.6 and 8.5
Chloride is to be less than 125 mg/l
Iron is to be less than 0.3 mg/l
Cu less than 0.1 mg/l
Conductivity is to be less than 400μS/cm (at 77°F [25°C])
7 grains/ gal (120 ppm)
Important
: Ensure that these limits are acceptable for the other water-side components in
the system.
