6" X 12"L VORTEX DOUBLE WALL BLACK PIPE VOD0004

The VOD0004 Vortex Double Wall Stove Pipe requires only 6 inches clearance to combustible walls and 8 inches clearance to combustible ceilings. This is a significant reduction from the 18-inch clearance required by single-wall stove pipe, allowing for more flexible installation options in tight spaces. Always verify that your installation meets local building codes and the appliance manufacturer's specifications.

No, double-wall stove pipe should never be cut as this will compromise the integrity of the connection system and void compliance with safety standards. The VOD0004 comes in a fixed 12-inch length (11 inches effective with overlap). If you need to adjust for specific heights, use the Vortex telescoping sections (model VOD0050) which can adjust from 18 to 30 inches, or combine different fixed-length sections to achieve your desired height.

The VOD0004 has a 6-inch inner diameter (AØ) which is the actual flue opening that matches your stove outlet, and a 7-inch outer diameter (BØ) which is the outside measurement of the pipe. The 1-inch difference creates the air-insulated space between the double walls that contains the thermal weave technology, keeping the outer surface cooler and allowing for reduced clearances to combustibles.

The exclusive thermal weave design in the stainless steel inner wall promotes even airflow between the double walls, resulting in lower outer wall temperatures for enhanced safety. This technology helps maintain high flue gas temperatures for better draft performance while keeping the exterior cooler to the touch. The improved airflow also helps minimize creosote buildup and extends the life of your venting system.

The VOD0004 Vortex Double Wall Stove Pipe is designed to connect your wood-burning appliance to a Class A chimney system (such as DuraTech, DuraPlus, or similar triple-wall chimney pipe). You'll need appropriate transition components like a wall thimble or ceiling support box to properly connect from this double-wall stove pipe to your chimney. The pipe is compatible with other Vortex double-wall components for a complete system.

The VOD0004 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 103 HT (Factory-Built Chimneys for Residential Type and Building Heating Appliances), and ULCS629. This comprehensive compliance ensures your installation meets code requirements for both residential and commercial applications.

The VOD0004 features an easy-connect installation system with predrilled holes and includes all necessary screws for assembly. The connection design has the male end pointing up on the outer wall and male end pointing down on the inner wall (which is correct for proper draft and creosote drainage). Each connection creates a 1-inch overlap, reducing the effective length. Simply align the sections, insert the provided screws through the predrilled holes, and tighten securely - no cutting, crimping, or special tools required.

No, the VOD0004 double-wall stove pipe is intended for interior use only as a connector between your wood-burning appliance and a wall thimble or ceiling support box. It should never be installed outdoors, inside a combustible wall, or inside a chimney chase. For outdoor or through-wall applications, you must transition to appropriate Class A chimney pipe (triple-wall insulated chimney) which is designed for those applications. Using connector pipe outdoors violates code, UL standards, and may void your homeowner's insurance policy.
