4" PELLET ADAPTER TO 6"Ø MASONRY CHIMNEY VOP0153

The VOP5153 is specifically designed to connect 4-inch pellet vent pipe from a pellet stove to an existing 6-inch masonry chimney liner. This adapter allows homeowners to retrofit modern pellet-burning appliances into homes with traditional masonry chimneys without expensive chimney modifications. The adapter fits into the masonry wall with a black trim plate covering the opening, while the appliance end connects to 4-inch pellet pipe and the chimney end connects to the 6-inch liner outlet.

No, the VOP5153 features a revolutionary gasket system that creates a leak-proof seal without requiring silicone sealant. This innovative design eliminates the mess and complexity of applying high-temperature silicone, while ensuring a secure, airtight connection that prevents dangerous exhaust leaks. The precision-formed ends and integrated gasket system provide professional-grade sealing performance right out of the box.

The VOP5153 complies with all major North American safety standards, including NFPA 211 (Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances), CSA B365 (Installation Code for Solid-Fuel-Burning Appliances and Equipment), UL 641 (Type L Low-Temperature Venting Systems), CAN/ULC S609 (Standard for Factory-Built Chimneys), and ULC/ORD C441. These certifications ensure the adapter meets rigorous safety requirements and is approved for residential installations throughout the United States and Canada.

The VOP5153 features premium dual-wall construction with an outer wall made of galvalume steel and an inner wall made of stainless steel. Galvalume steel provides exceptional corrosion resistance and durability for the exterior, while the stainless steel inner wall withstands the high temperatures and acidic condensates produced by pellet stove exhaust. This combination ensures long-lasting performance in demanding venting applications.

Yes, while designed primarily for wood pellet-burning stoves, the VOP5153 adapter is suitable for venting multiple biofuel types. It can safely handle exhaust from appliances burning wood pellets, corn, and other biomass fuels. The double-wall construction and stainless steel inner liner provide the necessary durability and temperature resistance for various alternative fuel sources, making it a versatile solution for multi-fuel heating systems.

The VOP5153 comes as a complete installation kit including the main masonry adapter body, a black trim plate for covering the masonry wall opening, and a 4-inch connector that fits inside the masonry adapter. This comprehensive package provides everything needed to connect your pellet vent pipe to an existing masonry chimney, eliminating the need to purchase multiple separate components.

While the VOP5153 features user-friendly design elements like the revolutionary gasket system and precision-formed ends, installation through masonry walls and connection to chimney liners should be performed by qualified professionals familiar with venting system requirements and local building codes. Professional installation ensures proper alignment, secure connections, adequate clearances from combustible materials, and compliance with NFPA 211 and other applicable safety standards. Improper installation can create serious safety hazards including carbon monoxide exposure and fire risk.

The smooth-weld technology used in manufacturing the VOP5153 creates virtually invisible seams that enhance both the appearance and performance of the adapter. These precision welds eliminate potential weak points where leaks could develop, improve overall structural integrity, and provide a clean, professional finish that complements any installation. The smooth seams also reduce turbulence in exhaust flow, contributing to more efficient venting performance.
