3" PELLET BLACK WALL PASS-THRU VOP0260

The primary difference is the inner pipe diameter: the VOP0230 is designed for 3-inch pellet vent systems, while the VOP0260 accommodates 4-inch systems. The larger 4-inch firestop is typically used with higher BTU-rated appliances or stoves with greater heating capacity. Both models feature identical construction quality with galvalume steel outer walls, stainless steel inner walls, and the same revolutionary gasket seal system.

Yes, absolutely. Building codes in both the United States and Canada mandate that a firestop must be installed at every location where the pellet vent pipe passes through a floor or ceiling. This is a critical safety requirement to prevent combustible materials from coming into contact with the pipe. Note that firestops are not required when the pipe passes through the roof itself (appropriate flashing is used instead).

Yes, the VOP0260 is designed for flexible installation and can be mounted from either above or below the floor joist, making it ideal for situations with limited access. This dual-installation capability is especially valuable in retrofit scenarios or when working in tight spaces like finished basements or attics. Simply cut the properly sized hole, position the firestop, and secure it with four fasteners at the corners.

No, the VOP0260 features an advanced gasket seal system that eliminates the need for silicone or other high-temperature sealants. This revolutionary design not only makes installation cleaner and faster but also ensures a consistent, reliable seal that won't degrade over time. The gasket system provides superior performance without the mess and additional expense of traditional sealants.

Yes, the VOP0260 is engineered for universal compatibility with all 4-inch pellet vent systems and multi-fuel appliances. It safely vents stoves burning wood pellets, corn, cherry pits, switch grass, coffee husks, walnut shells, soybeans, wheat, sunflower hulls, and other approved biofuels, as well as oil-burning appliances. The system is rated for continuous flue gas temperatures up to 570°F, making it suitable for virtually all residential and light commercial heating applications.

A firestop is used when the pellet vent pipe passes through a floor or ceiling inside the building structure to prevent combustibles from contacting the pipe. Roof flashing, on the other hand, is used where the pipe exits through the roof to create a weatherproof seal and direct water away from the penetration. When installing through an attic, you'll need both a firestop at the ceiling level and an attic insulation shield, plus roof flashing where the pipe exits.

The VOP0260 is covered under the manufacturer's limited lifetime warranty program, which typically provides 100% replacement coverage for 15 years from the original purchase date, then 50% coverage thereafter. Warranty coverage requires professional installation according to manufacturer specifications, compliance with annual maintenance requirements, and burning only approved fuels. Keep your proof of purchase and product registration. Note that labor and installation costs are not included in warranty coverage.
