The LENNOX 96m57 is a PVC vent pipe designed for use in HVAC venting applications. Measuring 2 inches in diameter and 15.75 inches in length, this pipe section provides a rigid, corrosion-resistant conduit for routing exhaust or intake air in high-efficiency heating and cooling systems. PVC construction makes it suitable for the mildly acidic condensate environments common in condensing furnace and heat pump vent systems. Licensed HVAC technicians install this component as part of a complete venting assembly.
This vent pipe is used in residential HVAC installations where PVC venting is specified, typically in conjunction with 90-plus AFUE condensing furnaces or other sealed-combustion equipment. The 2-inch diameter fits standard PVC vent fittings and couplings used in direct-vent and category IV venting configurations. It is sized for inline sections where a shorter rigid segment is required to complete a venting run between components or through a wall or floor penetration.
Designed as an OEM-style replacement vent pipe segment for Lennox HVAC systems requiring 2-inch PVC venting.
Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the appliance manufacturer's venting instructions. Shut down and de-energize the equipment before disconnecting any existing vent sections. Use approved PVC primer and cement when joining this pipe to fittings or couplings, and ensure all joints are fully cured before returning the system to operation. Verify that the completed vent assembly meets all required slope, support, and clearance requirements per the applicable installation manual.
