Installation of the IL gas vent pipe is straightforward, yet adhering to best practices is essential for safety and optimal performance. • Ensure the appliance you are venting is naturally aspirated and fitted with either a draught hood or diverter. • Follow building regulations and manufacturer guidelines when positioning the vent pipe; always maintain a minimum distance of 50mm from any combustible materials. • For best results, use a certified gas installer to carry out the installation. • Do not use the vent pipe for condensing or positive pressure applications. • Verify that the push fit and twist lock joints are securely engaged and properly aligned to prevent any leakage.
