The Boiler Adaptor Ø 500 from the SWPro range is an essential component for connecting your appliance to the modular single wall flue system. Crafted from high-grade 316L Stainless Steel, the adaptor is built to last, offering superior resistance to high temperatures and varying flue gas pressures. The SWPro system is approved for both high and low-temperature applications, making it versatile for boilers, ovens, ventilation systems, and chimney shaft liners.
Featuring a high-pressure sealing gasket P1/H1, this adaptor ensures a secure and efficient connection, reducing the risk of leaks and enhancing overall performance. The push-fit jointing system, complemented by a Locking Band, simplifies installation, while the CE mark underlines its compliance with stringent safety standards. For condensing appliances, sealing the adaptor and appliance outlet with silicone sealant is recommended unless an integrated seal is present.
Ensure a 50mm clearance from combustible materials such as wood and plasterboard for safe operation.
