  • The CBM-225 model is versatile to install in most residential installations, either wall or floor-mounted.
  • With its low-profile design, the CBM-225 is purpose-built for high-efficiency, gas-fired appliances with a low condensate drain.

The CBM-225 is well-suited for most residential installations of high-efficiency, gas-fired appliances such as condensing boilers, furnaces, and hot water heaters rated approximately 225 MBH.



The effects of untreated acidic condensate can develop quickly, corroding copper, iron pipes, or floor drains in a matter of months, not years. Fortunately, condensate neutralizers are relatively inexpensive, and they can save property owners from expensive damage.

JJM® condensate neutralizers are quick and easy to install, at the initial installation or during annual maintenance of the high-efficiency, gas-fired appliance. Neutralizers should be installed by a licensed, trained Installer or Service Technician.
