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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable length: extends from 3 inches to 10 inches within the 12-inch body\u003c\/li\u003e\n\u003cli\u003eTwist-lock construction for secure, tool-assisted field assembly\u003c\/li\u003e\n\u003cli\u003eDouble-wall, air-insulated design with super ferritic stainless steel inner wall\u003c\/li\u003e\n\u003cli\u003eLaser-welded Galvalume outer wall for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eApproved for both vertical and horizontal installations\u003c\/li\u003e\n\u003cli\u003eUL Listed for 3-inch clearance to combustibles in USA and Canada\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Type PL pellet vent replacement or extension pipe for residential wood pellet stoves and inserts that require a 3-inch diameter pellet vent system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hearth or HVAC technician familiar with Type PL pellet vent systems and applicable local codes.
