The Boiler adaptor - Ø 100 is a crucial component in the SWPro modular single wall flue system, designed to provide optimal performance for a variety of applications, including boilers, ovens, and ventilation systems. Constructed from high-grade 316L stainless steel, this adaptor ensures durability and longevity. The SWPro system is CE marked and suitable for both high and low temperature, non-condensing and condensing applications, handling flue gases under positive or negative pressure effectively.
The robust design includes a high-pressure sealing gasket P1/H1, making it versatile for both commercial and domestic uses. Installation is straightforward, thanks to the push-fit jointing system secured with a Locking Band. When dealing with P1 and H1 installations, jointing gaskets must be fitted on every joint, and a 50mm clearance from any combustible materials must be maintained for safety.
