To establish a weather-resistant breach through the roof deck, the utilization of DuraTech flashing is necessary. Apply a non-hardening 500° F high-temperature sealant to secure the inner edge of the collar to the chimney pipe. This product is composed of aluminum. Specification: Diameter: 5-6" Material: Aluminum Clearance: 2" Listings: The product is compliant with UL 103 height standard, with UL file reference being #MH7399. It also meets the Canadian S610 standard. Apply using a sealant that remains non-hardening at 500° high temperature. 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. .
