It offers a high-quality product for use with the DuraTech chimney system. This stainless steel external trim protects the wall thimble (sold separately) from the weather. DuraTech is a double-wall chimney system for use with wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, or other appliances fueled by wood. DuraTech is designed for normal, continuous operation at 1,000 degree flue gas temps.

Stove Pipe: More accurately referred to as black pipe or single wall pipe, is generally composed of black galvanized steel. Its primary use is indoors, serving as the conduit for smoke from the stove until it reaches the point of exit in the home — usually a wall or ceiling. Chimney Pipe: Once the point of transition through a wall or ceiling is reached, the chimney pipe (also called class A pipe, triple-wall pipe, or insulated pipe) takes over. This refers specifically to class A chimney pipe, designed to safely vent the smoke outside of the home. In summary, while these two types of pipes serve a similar function, their application, material, and design differentiate them. The stove pipe works inside, transitioning to the chimney pipe when the home's boundary is reached. Class A Chimney Pipe: A Comprehensive Guide Often referred to by multiple names such as double-wall chimney pipe, triple-wall chimney pipe, all-fuel pipe, or insulated chimney pipe, Class A chimney pipe is primarily used to vent the high-temperature exhaust that results from burning wood, coal, or oil in various appliances. These appliances can include fireplaces, stoves, boilers and furnaces. Although not every venting system needs a Class A pipe, this type of pipe is a strict requirement for all wood-burning fireplaces and stoves. It is important to state that Class A chimney pipe is UL-listed. This certification allows its application across a wide range of vent pipes produced by various manufacturers as well as its use with a wide array of fireplaces, stoves, inserts, and furnaces. However, caution has to be taken when using Class A chimney pipe. Mixing and using different brands of Class A chimney pipe within one chimney system is not advisable unless it is specifically permitted by the manufacturer. The reasoning behind this is that all brands of Class A pipes are engineered distinctly and should be used as a comprehensive system - from beginning to end. To modify or enhance your existing chimney system, it's essential to identify your current Class A pipe's make and model. Ideally, you should buy a similarly typified unit. But suppose your existing pipe's make and model are from a phased-out or outdated brand. In that case, a complete reinstallation of your chimney system may be inevitable. Plan Your Chimney Pipe Installation: Firstly, determine the diameter of the appliance flue outlet. Then, choose a chimney and a connector stovepipe, which could be either DVL or Dura-Black, that matches the same diameter size as the appliance flue outlet. Evaluate the inclination of the roof. For instance, a 6/12 pitch denotes a vertical elevation of 6 inches over a horizontal stretch of 12 inches. Choose the flashing that is most relevant. In compliance with the building codes, you need to calculate the lowest possible height of the chimney from the rooftop. These regulations demand that the chimney extends a minimum of 3 feet above the point where it penetrates the roof. Additionally, it must stand 2 feet taller than any part of a structure that exists within a 10-foot radius. Check whether the installation procedure is for a 'through-the-roof' or a 'through-the-wall' setup. Additional parts like a Wall Thimble, Tee/Cap, Tee Support, and Wall Straps are necessary for a 'through-the-wall' deployment. For optimal results, we recommend positioning the chimney inside the structure when feasible. A cold chimney exterior will lead to diminished draft and increased creosote production. To steer clear of rafters or any obstructive items, you need to calculate two things - the needed horizontal distance and the accessible vertical height. There are two kinds of elbows accessible - 15° and 30°. However, please note that in the US, it's disallowed to use elbows that exceed 30°. To guarantee sufficient support, make use of elbow straps. Calculate the total required lengths of both the chimney and stovepipe for the installation. If you're utilizing a 5”- 8” DuraTech pipe, deduct 1.25" per joint to get the installed length. For a pipe diameter lying between 10” and 24”, a deduction of 0.75" per joint is necessary. A reduction of 1.25" per DuraBlack stovepipe joint and 1.5" per DVL stovepipe joint must also be factored in. The lowest acceptable height for a chimney located at sea level, assuming it's straight and vertical, should range from 10 to 15 feet above the appliance outlet. However, factors such as higher elevations, or the inclusion of junctions or a tee, will necessitate an increase of roughly 30% to 60% in the chimney's height. This is crucial to ensure an effective draft. Ensure Fire Safety. Always keep a minimum of 2 inches distance from combustible materials. Adhere to your local construction regulations and arrange for a certified expert to carry out an inspection of your chimney. Some More Installation Tips: You are required to use DVL/DuraBlack Chimney Adapter when you are linking DVL pipe to either a Ceiling Support Box or a Finishing Collar. In addition, when the connection involves DuraBlack pipe, it is mandatory to use a DVL/DuraBlack Chimney Adapter, a DuraBlack Slip Connector, or a Snap-Lock Adapter. A Wall Thimble should be utilized in all instances where horizontal through-the-wall installations are carried out. It must be properly matched with a chimney pipe of an appropriate length. In instances where the walls are considerably thicker, the Wall Thimble's telescoping parts can be detached allowing the insertion of a custom-made extension. It's mandatory to use an Attic Insulation Shield in all installations that penetrate through an attic, regardless of the attic's insulation status. It is mandatory to utilize the Firestop Radiation Shield when a chimney traverses through a floor or ceiling without having a support box. .
