Specification Sheet

A. O. Smith flue-side neutralizing tubes are designed to raise the pH level of the
condensate discharged by high-efficiency boilers and water heaters.
INCREASES pH OF CONDENSATE BY 1-3 TIMES
■ Results in a reduction of acidity of 10 to 30
times of the condensate leaving the appliance.
PREVENTS POSSIBLE DAMAGE TO:
■ Cast Iron Soil Pipe
■ ABS Pipe
■ Septic Tanks
■ Plants
■ Waste Water Treatment Plants
■ Other Waste Water Equipment and Components
