1. Installing the boiler on a 4 inch to 6 inch housekeeping pad is recommended to ensure proper condensate
drainage.
2. Use 3/4” CPVC pipe to plumb each condensate drain separately to a suitable floor drain or collection system.
3. Each condensate drain must contain a trap or siphon/pigtail to provide at least 3 inches of standing water, to
prevent flue gas flow through the condensate piping. To construct the trap, connect to the 3/4” condensate
drain, route the piping downward until the standing water in the trap is not higher than the bottom of the boiler.
4. Install the condensate plumbing as shown in the following diagram.
5. All condensate plumbing must be protected from freezing. Do no locate the condensate piping such that an ice
dam of frozen condensate can block the outlet.
5.4 Condensate Neutralization System (optional)
Although only slightly acidic (3-5 PH), boiler 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 Riverside Hydronics® 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 boiler.
4. For proper operation, the boiler 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.
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.
