5.1 Condensate Neutralization System (optional)
Condensate is only slightly acidic (3-5 PH), however this slight acidity can be neutralized by routing it through an
optional Condensate Neutralization System. Some “authorities having jurisdiction” require such neutralization before
condensate disposal through a suitable drain. Condensate is neutralized while slowly flowing through a container
filled with renewable crushed limestone. The condensate neutralizer reduces or avoids the need for separate
chemical treatment or dilution using substantial quantities of tap water. Contact your local Riverside Hydronics®
representative to obtain a Condensate Neutralization System and follow the instructions included for assembly and
connection.
Condensate Neutralization Systems (CNS) Installation Requirements:
1. Follow the steps 1 through 6 in the Condensate Drain, Trap & Disposal section above.
2. The Condensate Neutralization System (CNS) must be mounted horizontally and level, with the mounting strap
legs on the floor.
3. Locate the CNS in a convenient place between the condensate outlet and a suitable drain and where the 3”
threaded end cap can be removed to recharge the Neutralizer with crushed limestone.
a. The CNS must be located such that condensate will flow downhill from the condensate trap outlet to the
inlet on one end of the CNS and downhill from the other end of the CHS to the drain. If this continuous
downhill flow is not maintained, the trap will not properly operate and condensate could back up into the
boiler.
b. Follow the instructions included in the Condensate Neutralization System for connecting the supplied 1/2"
Vinyl tubing.
4. Keep the Condensate Neutralization System closed at all times, except when the appliance is turned off for
maintenance to recharge the condensate neutralizer with limestone.
WARNING: Keep the Condensate Neutralization System closed at all times the appliance is operating. The
system must remain closed to prevent hazardous products combustion from continually enter the room.
Failure to keep the Condensate Neutralization System closed during appliance operation can cause property
damage, personal injury, exposure to hazardous materials or death.
