Duravent 4PVL-24R Pellet Vent Pipe 4x24 Inches Double Wall

Product Description

The DURAVENT 4PVL-24R is a double-wall, air-insulated pellet vent pipe section designed for venting wood pellet stoves and inserts. It measures 4 inches inner diameter by 24 inches in length, with a 4-1/2 inch outer diameter. The inner wall is constructed from .012 inch super ferritic stainless steel, and the outer wall is .018 inch laser-welded Galvalume. The fully unitized, twist-lock construction simplifies field assembly and ensures a secure, repeatable connection. This pipe section is UL Listed and carries a 3-inch clearance-to-combustibles rating for use in both the USA and Canada. It is also required for pellet appliance installations at elevations above 4,000 feet.

This pipe section is suitable for both vertical and horizontal pellet vent runs in residential and light-commercial settings. It is specifically engineered for stoves and inserts that burn wood pellets, where exhaust temperatures and combustion byproducts differ from standard wood-burning or gas appliances. Typical installations include freestanding pellet stoves and fireplace inserts routed through interior chases or exterior walls. The twist-lock design is well suited to service calls requiring quick disassembly and reassembly of vent sections.
