How to use

Select an appropriate roof location that provides correct alignment with the interior flue route and complies with ventilation clearances and building regulations. Cut or prepare the roofing and supporting structure to accommodate the pipe, ensuring proper flashing and sealing to prevent water ingress. Connect the WADEX Roof101 pipe to the appliance outlet or adjoining flue segments using compatible fittings, and secure joints according to accepted chimney installation practice. Ensure the entire flue assembly has adequate support and that combustion appliances are commissioned and tested after installation.

Usage recommendations

Installations must follow local building codes, ventilation standards, and the appliance manufacturer’s instructions. Use appropriate sealing, flashing, and fireproofing materials where the pipe penetrates combustible structures. Have the completed flue system inspected and, if required, certificated by a qualified technician before operating heating equipment.
