Condensate Piping and Trap with Optional Condensate Neutralizer
6.1 Condensate Neutralization System (optional)
Although only slightly acidic (3-5 PH), condensate can be routed through an optional Condensate Neutralization
System (see image below) to become pH neutral allowing for disposal into any drain or sewer system without
concern for corrosion. Condensate slowly flows through a neutralization bath filled with renewable crushed limestone
becoming neutralized thus avoiding chemical treatment or dilution using substantial quantities of tap water. To obtain
a Condensate Neutralization System, please contact your local PVI representative.
1. Follow the steps 1 through 4 in the Condensate Drain, Trap & Disposal section above.
2. Locate the Condensate Neutralization System in the condensate piping, as shown in the FIELD INSTALLED
CONDENSATE DIAGRAM above.
3. Position with removable crushed limestone fill-cap in vertical position only. The bottom of the condensate
neutralization system outlet pipe must not be higher than the bottom of the water heater.
4. For proper operation, the water heater condensate outlet must be plumbed with CPVC plastic pipe to the lowest
fitting of the Condensate Neutralization System, connecting to the “INLET” as shown in the graphic below.
5. Keep the Condensate Neutralization System closed at all times, except for maintenance.
Optional Condensate Neutralization System
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 can cause property damage, personal injury,
exposure to hazardous materials or loss of life.
