A chimney chase cover is a crucial component of a chimney system that protects the chimney chase and prevents water from entering the flue. It is typically made of metal, such as stainless steel or galvanized steel, and is custom fabricated to fit the specific dimensions of the chimney chase. In this article, we will explore the process of chimney chase cover fabrication, from initial measurements to the final installation.
Measuring and Assessment: The first step in chimney chase cover fabrication is accurate measurement and assessment of the chimney chase. A professional chimney technician will take precise measurements of the chase’s width, length, and height, as well as the dimensions of any protrusions or vents. This information is crucial for creating a custom-fit chimney chase cover that will effectively seal the chimney.
Material Selection: Once the measurements are obtained, the next step is selecting the appropriate material for the chimney chase cover. Stainless steel and galvanized steel are popular choices due to their durability, resistance to corrosion, and ability to withstand extreme weather conditions. The thickness of the metal is also considered, with thicker gauges providing enhanced durability and longevity.
Fabrication Process: The fabrication process involves cutting and shaping the selected metal sheet to create the chimney chase cover. The metal is usually cut using a shear or a plasma cutter, ensuring precise and clean edges. The sheet is then formed into the desired shape using specialized tools, such as a brake press or a metal roller. This process allows the fabrication of various designs, including flat covers, pitched covers, or covers with slopes to promote water runoff.
Welding and Assembly: If the chimney chase cover design requires multiple pieces, the next step is to weld the sections together to form a single, cohesive unit. Welding ensures a strong bond between the metal pieces, making the chimney chase cover resistant to leakage and structural failures. Careful attention is paid to the welding process to ensure a secure and watertight seal.
Adding Flanges and Curb: To further enhance the functionality of the chimney chase cover, flanges and a curb may be added. Flanges are bent edges along the perimeter of the cover, allowing for easy installation and providing an additional layer of protection against water penetration. A curb, on the other hand, is a raised edge around the cover’s opening, preventing water from entering the chimney while still allowing the free flow of exhaust gases.
Finishing and Coating: After the fabrication and assembly process, the chimney chase cover is carefully inspected for any imperfections or sharp edges. Any rough edges are smoothed out, ensuring a safe and aesthetically pleasing product. Additionally, a protective coating or paint can be applied to the cover to provide further resistance against corrosion and to match the desired appearance.
Installation: The final step is the installation of the fabricated chimney chase cover. A professional chimney technician will secure the cover onto the chimney chase, ensuring a proper fit and alignment. Sealing materials, such as silicone or high-temperature caulk, are used to create a watertight seal between the cover and the chase. The installation process also involves securing the cover with screws or other appropriate fasteners to ensure stability.
The process of chimney chase cover fabrication involves precise measurements, material selection, cutting, shaping, welding, and assembly. By following these steps, a custom-made chimney chase cover can be created to fit the specific dimensions of the chimney chase. Proper installation of the fabricated cover provides essential protection against water damage, improving the longevity and performance of the chimney system.
