Description
The Lochinvar & A.O. Smith 100289339 Condensate Neutralizer (CN2-300C) is a purpose-built solution for managing acidic condensate produced by high-efficiency condensing boilers and water heaters rated up to 300,000 BTU. Condensing appliances generate low-pH condensate as a byproduct of their high-efficiency combustion process. Left untreated, this acidic condensate can corrode drain lines, damage plumbing infrastructure, and violate local codes. The CN2-300C neutralizes the condensate before it reaches the drain, protecting your system and ensuring code compliance.
