Centrotherm 250407108000 Vent Snorkel Termination Kit 3 in

Product Description

The CENTROTHERM 250407108000 is a gasketed polypropylene vent snorkel termination kit designed for direct-vent and sealed-combustion appliance exhaust systems. Built from polypropylene, this termination kit is rated for continuous service up to 230 degrees F, making it suited for mid-efficiency and high-efficiency gas appliance venting applications. The kit ships in a 3-inch diameter by 1-foot configuration and includes a pre-installed gasket to maintain a sealed, weathertight connection at the termination point. Licensed HVAC technicians and plumbers install this fitting as the outdoor termination for polypropylene vent systems.

This termination kit is intended for use with 3-inch polypropylene concentric or single-pipe vent systems on residential and light-commercial gas appliances including condensing furnaces, boilers, and water heaters that require a snorkel-style exterior wall or roof termination. The snorkel profile provides protection against wind-driven rain and debris intrusion at the exhaust outlet. Installers working with polypropylene vent systems in cold or coastal climates commonly specify this type of termination for its chemical resistance and durability.

Key Features

• Rated up to 230 degrees F for continuous service in high-efficiency appliance vent applications
• 3-inch diameter by 1-foot length fits standard polypropylene vent system sizing
• Pre-installed gasket provides a sealed, weathertight termination connection
• Polypropylene construction resists condensate, acidic flue gases, and UV degradation
• Snorkel-profile termination guards against wind, rain, and debris intrusion at the exhaust outlet

Compatibility

Designed as an OEM-style termination component for 3-inch polypropylene vent systems on condensing gas appliances requiring a snorkel-style exterior termination.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable mechanical codes including the IFGC. Shut off the gas supply and allow the appliance to cool completely before servicing the vent system. Ensure the termination location meets required clearances from windows, doors, gas meters, and grade level as specified by local code. Do not install without the gasket seated properly, as an unsealed joint can allow flue gas or moisture infiltration.
