Duravent 3PVL-A12R Adjustable Pellet Vent Pipe 3x12 in

Product Description

The DURAVENT 3PVL-A12R is an adjustable double-wall pellet vent pipe designed for wood pellet stoves and inserts in residential installations. It features a fully unitized, twist-lock construction that allows length adjustment from 3 inches to 10 inches within its 12-inch nominal size. The inner wall is constructed from .012-inch super ferritic stainless steel, and the outer wall is .018-inch laser-welded Galvalume, creating an air-insulated assembly. The pipe measures 3-5/8 inches outer diameter and is UL Listed with a 3-inch clearance to combustibles rating in both the USA and Canada. Licensed HVAC or hearth professionals typically handle installation.

This pipe is suited for both vertical and horizontal pellet vent runs in residential settings. It is intended for stoves and inserts that burn wood pellets, where a dedicated Type PL vent system is required. The adjustable length makes it practical for fitting runs where fixed-length sections would leave gaps or require excessive cutting. Two units are included per package, which is useful when building multi-section vent runs in a single service call.

Installation Notes

Installation should be performed by a qualified hearth or HVAC technician familiar with Type PL pellet vent systems and applicable local codes. Ensure the stove or insert is completely cooled and de-energized before servicing the vent system. Follow the manufacturer's vent layout instructions and maintain the required 3-inch clearance to combustibles throughout the run. Do not mix this vent pipe with incompatible vent types or brands without verifying connector compatibility.
