6" X 24"L VORTEX DOUBLE WALL BLACK PIPE VOD0010

The VOD0010 double wall stove pipe requires only 6 inches clearance to combustible walls and 8 inches clearance to combustible ceilings. This is a significant safety advantage over single wall stove pipe, which requires 18 inches clearance to combustibles. Clearance to non-combustible materials like brick or cement is 0 inches, though the pipe should not actually touch these surfaces. Always check your appliance manufacturer's clearance requirements and use the larger clearance if there's a conflict between specifications.

No, double wall stove pipe should never be cut. The VOD0010 system is designed with telescoping sections and adjustable lengths that eliminate the need for cutting and crimping. If you need to adjust the height, use the available telescoping sections which come in various convenient lengths and easily adjust for a perfect fit. The system's easy-to-connect design ensures proper installation without modification to individual components.

All pipe sections must be securely fastened together using a minimum of three #8 x 1/2 inch self-drilling screws at each joint. This applies to connections between pipe sections, stove adapters, tees, elbows, wall thimbles, and ceiling support connectors. Drill at least three 1/8 inch holes and fasten with the appropriate screws to ensure safe, stable connections. For horizontal runs exceeding 4 feet, you must use a pipe hanger, with additional hangers required for every 4 feet thereafter.

The double wall connector pipe system must be cleaned and inspected on an annual basis by a professional chimney sweep at intervals of no more than 12 months, starting from the date of purchase. Use a plastic, wood, or flexible steel brush for cleaning—never use chemical chimney cleaners as they can mix with creosote deposits to form corrosive acids that accelerate steel deterioration. Regular maintenance is essential for safety, optimal performance, and maintaining warranty coverage.

If a flue fire occurs, immediately close all appliance draft openings and call your local Fire Department. Do not attempt to use the appliance again until the entire system—including the chimney, connector pipe, and stove—has been thoroughly inspected and approved by a professional chimney sweep and/or Fire Department Inspector. After any chimney fire, professional inspection is mandatory to ensure the system is safe to operate and to prevent future dangerous situations.

You should only use double wall stove pipe components and accessories from the same manufacturer. Do not mix this system with other manufacturers' products or with single wall stove pipe, as doing so can compromise safety, void warranties, and violate safety certifications. However, many double wall systems like Rock-Vent are compatible with brands such as Ventis, Champion, and Nexvent. Check with your supplier to confirm compatibility before purchasing.

Most quality double wall stove pipe systems come with a limited lifetime warranty covering defects in material and workmanship when properly installed, maintained, and used in residential applications. The warranty typically provides 100% coverage for 15 years from purchase date and 50% thereafter. Warranty applies only to the original purchaser in residential installations and requires annual professional cleaning and inspection. Labor and installation costs are not covered. Always retain your proof of purchase for warranty claims.

While there's no absolute limitation on total pipe length except as stipulated in NFPA 211 (USA) or CSA B365 (Canada) standards, manufacturers recommend a maximum of 15 feet if there's an offset in your installation. Without an offset, do not exceed 20 feet of total pipe length. Longer runs and multiple offsets can reduce draft efficiency and increase creosote buildup. The assembly should be as short and direct as possible between your stove and chimney for optimal performance and safety.
