Centrotherm 250407208020 Vent Snorkel Termination Kit 4in

Product Description

The CENTROTHERM 250407208020 is a gasketed polypropylene vent snorkel termination kit designed for direct-vent and sidewall exhaust applications in residential and light commercial heating systems. Measuring 4 inches in diameter by 1 foot in length, this snorkel termination provides a weatherproof, code-ready exhaust outlet at the point of wall penetration. The polypropylene construction is rated up to 230 degrees F, making it suitable for the flue gas temperatures produced by high-efficiency condensing furnaces and boilers. HVAC technicians and plumbers install this kit as the final termination component on Category IV or polypropylene vent systems where a snorkel-style outlet is specified.

This termination kit is used in sidewall venting configurations for high-efficiency condensing appliances, including gas furnaces and boilers that exhaust at low temperatures through plastic vent pipe. The snorkel profile directs exhaust gases downward and away from the structure, helping prevent re-entrainment of flue gases and reducing weather intrusion at the termination point. The included gasket ensures a sealed connection at the wall plate. It is suitable for both new installations and replacement of existing snorkel terminations where a 4-inch diameter sidewall outlet is required.

Key Features

• Polypropylene construction rated up to 230 degrees F for high-efficiency condensing appliance exhaust
• Snorkel-style outlet directs exhaust gases downward to reduce re-entrainment and weather intrusion
• Gasketed design provides a sealed, weathertight connection at the wall penetration
• 4-inch diameter by 1-foot length fits standard Category IV sidewall vent configurations

Compatibility

Designed as an OEM-style termination component for 4-inch polypropylene Category IV vent systems used with high-efficiency condensing gas furnaces and boilers.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable mechanical codes such as the IFGC. Shut off and de-energize the connected appliance before working on the vent system. Ensure the snorkel termination is positioned and oriented per code clearance requirements for sidewall exhaust outlets, including minimum clearances from grade, openings, and gas meters. Do not use this kit with vent systems exceeding the stated temperature rating.
