4" PELLET ATTIC INSULATION SHIELD VOP0301

Yes, the VOP0301 attic insulation shield (firestop) is required by code whenever pellet vent pipe passes through a floor or ceiling. This safety component prevents combustible materials from coming into contact with the vent pipe and ensures proper clearances are maintained. It's mandated by NFPA 211 and other building codes for safe pellet stove installations.

While the terms are often used interchangeably, an attic insulation shield specifically protects the pipe when passing through insulated spaces like attics, preventing blown-in or batt insulation from contacting the vent pipe. The VOP0301 serves both functions, providing structural support at floor/ceiling penetrations and protecting against insulation contact.

The VOP0301 can be installed from either above or below the floor or ceiling joists, providing installation flexibility. However, when used as an attic insulation shield, it must be installed from the top. Secure it using four 8-penny nails or #8 x 1-1/2 inch wood screws at each corner for proper support.

The included storm collar should be sealed where it meets the vent pipe using a high-temperature sealant or non-hardening waterproof caulk to prevent moisture infiltration. The VOP0301's revolutionary gasket system means the pipe connections themselves don't require silicone, but the storm collar interface benefits from proper sealing.

The rough opening should accommodate the 7.75-inch shield diameter of the VOP0301 while maintaining the required 1-inch clearance to combustible materials. Typically, a 9-10 inch square or round opening is appropriate. Always consult local building codes and the appliance manufacturer's specifications for exact requirements.

The VOP0301 is designed specifically for 4-inch pellet vent pipe systems and is part of the Vortex pellet vent product line. For best results and warranty compliance, use it with matching Vortex system components. While it may work with other brands' 4-inch systems, compatibility should be verified before installation.

Maintain a minimum 1-inch air space clearance between the vent pipe and any combustible materials such as wood framing, insulation, or drywall. Never fill this clearance space with insulation or other materials. The VOP0301 firestop helps maintain this critical safety clearance at floor and ceiling penetrations.

Warranty coverage varies by manufacturer and installation. Professional installation by certified installers is recommended and may be required for full warranty protection. Contact the retailer or manufacturer for specific warranty terms, as coverage can range from several years to limited lifetime depending on the product line and installation conditions.
