The INTERNATIONAL COMFORT PRODUCTS naha00201hh is a condensate freeze protection kit designed for high-efficiency gas furnaces that produce condensate as a byproduct of combustion. These furnaces route liquid condensate through drain lines that are vulnerable to freezing in cold ambient conditions, which can cause system faults, drain backups, or heat exchanger damage. This kit provides the components needed to protect the condensate drain system from freezing, keeping the furnace operational during cold-weather service conditions. It is installed by licensed HVAC technicians as part of routine maintenance or as a corrective measure when freeze-related condensate issues are diagnosed.
This freeze protection kit is intended for use with high-efficiency condensing gas furnaces operating in environments where condensate lines are exposed to low ambient temperatures. Based on the supplier description, compatible units include N9MSE series gas furnaces. Install this kit when drain lines run through unconditioned spaces such as attics, crawlspaces, or exterior walls where freezing is a risk. It is appropriate for both residential and light commercial applications where condensate management is part of the system design.
Based on supplier data, this kit is referenced for use with N9MSE series gas furnaces. Verify the full model number of the furnace before installation to confirm fitment.
Installation should be performed by a licensed HVAC technician familiar with high-efficiency condensing furnace systems. Shut off power to the furnace at the disconnect and set the thermostat to the off position before beginning work. Follow the furnace manufacturer service documentation and applicable local mechanical codes when routing or modifying condensate drain components. Do not restore power until all connections are secure and the condensate system has been verified for proper flow and drainage.
