Noritz CVP-40ADJ Concentric Adjustable Vent Pipe

Product Description

The NORITZ CVP-40ADJ is a Category III stainless steel concentric vent pipe designed for use with Noritz DVC-series tankless gas water heaters. It adjusts from 22.8 inches to 40.6 inches in length, allowing installers to fit the vent without requiring precise heater placement. Both intake and exhaust pass through a single wall penetration using a concentric design, which simplifies the rough-in and reduces the number of wall openings required. The push-on connection makes assembly straightforward during installation. Licensed plumbers and HVAC technicians working on tankless water heater projects will find this vent pipe a direct fit for compatible Noritz DVC models.

The CVP-40ADJ is intended for residential and light commercial tankless gas water heater installations where a single-wall concentric vent penetration is specified. Its adjustable length range accommodates varying wall thicknesses and heater placement distances without field cutting or custom fabrication. Compatible models listed by the manufacturer include the NR83DVC, NR98DVC, and NC199DVC. This vent pipe is particularly useful in retrofit applications where the heater position relative to the exterior wall may not be perfectly fixed.

Follow all applicable local mechanical codes and the manufacturer installation instructions for proper sealing at the wall penetration. Verify the adjusted pipe length and confirm a secure push-on connection before returning the unit to service.
