6" X 18"L VORTEX DOUBLE WALL SLIP SECTION VOD0077

A slip section is designed to slide over standard pipe lengths to allow for easy adjustment during installation. The VOD0077 slip section is specifically engineered to connect irregular lengths between your wood stove and chimney, providing flexibility when exact measurements don't align with standard fixed-length pipes. This eliminates the need for cutting pipe sections, which would compromise the double-wall integrity and void warranty coverage. The 18-inch length provides substantial adjustment range while maintaining proper clearances and safety standards.

The Vortex double wall slip section requires a minimum clearance of 6 inches to combustible side walls and combustible ceilings. This is a significant advantage over single-wall stove pipe, which requires 18 inches of clearance. If your assembled pipe section has no adjustable length sections, clearances may be reduced to 5 inches to combustible side walls and ceilings. These reduced clearances allow you to position your wood stove closer to walls, maximizing usable floor space while maintaining safety compliance with NFPA 211 standards.

No, you should only use Vortex Double Wall connector pipe and listed components together. The manufacturer explicitly warns against mixing products from different manufacturers, as this can compromise safety, void your warranty, and violate building codes. Each pipe system is tested and certified as a complete unit, and mixing components may result in improper fit, inadequate clearances, or failure during operation. Always purchase matching Vortex components to ensure proper installation and maintain compliance with UL 103 HT and ULC S629 standards.

The slip section should be connected to adjacent pipe sections using a minimum of three #8 x 1/2" self-tapping screws at each joint. Before securing, slide the slip section over standard pipe lengths to achieve your desired total length. Ensure all sections are properly aligned and fully engaged before drilling and installing screws. For horizontal runs exceeding 4 feet, you must use pipe hangers for additional support, with an additional hanger for every 4 feet thereafter. All connections should be solid and secure to prevent separation during thermal expansion and operation.

To maintain your limited lifetime warranty coverage for residential installations, the double wall connector pipe system must be cleaned and inspected annually by a qualified chimney professional at intervals of no more than 12 months, starting from the date of purchase. Regular cleaning removes creosote, soot, and ash deposits that can accelerate corrosion and reduce efficiency. The warranty covers replacement of defective components when the pipe is used with a residential wood appliance certified by an accredited laboratory and operated within the maximum continuous temperature of 1,200°F. Chemical cleaners should never be used as they can be highly corrosive.

While there is no absolute limitation to the total length of Vortex Double Wall connector pipe (except as stipulated in NFPA 211 or CSA B365), the manufacturer recommends a maximum of 15 feet if there is an offset in your installation. Without an offset, do not exceed 20 feet of total connector pipe length. Longer runs can result in poor draft, excessive creosote buildup, and reduced appliance efficiency. The assembly should be as short and direct as possible between your stove and chimney. Using two 45-degree elbows is often preferable to a single 90-degree elbow to maintain better draft performance.

The exclusive thermal weave featured in the stainless-steel inner wall promotes even airflow between the inner and outer pipe walls while maintaining lower outer wall temperatures. This air-insulated design keeps flue gas temperatures higher, which enhances draft performance, reduces smoking at startup, and minimizes the formation of creosote, soot, and moisture buildup. The cooler outer wall temperatures allow for reduced clearances to combustibles (6 inches versus 18 inches for single wall), making installation safer and more space-efficient. The stainless steel inner wall also heats up faster and stays hot longer than other materials, improving overall system efficiency.

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 chimney, connector pipe, and stove have been thoroughly inspected by a professional chimney sweep and/or Fire Department Inspector. Chimney fires can reach extremely high temperatures that may damage pipe components, weaken joints, or compromise the structural integrity of your venting system. After inspection, any damaged components must be replaced before resuming use. Regular annual cleaning and inspection significantly reduces the risk of chimney fires by removing combustible creosote deposits.
