The Navien Roof Terminal Adaptor is designed to connect a Navien condensing boiler to a vertical 60/100mm roof flue terminal. It provides the transition needed between the boiler’s flue outlet or existing flue section and the vertical terminal used for roof penetration installations.
Used as part of a Gas Boiler Flues vertical flue assembly, this adaptor ensures correct airflow, secure sealing, and compliance with flue installation guidelines. The adaptor does not include flashing, allowing installers to select the appropriate flashing kit for flat or pitched roofs based on site requirements.
Constructed with an aluminium inner duct and uPVC outer body, the adaptor integrates with Navien’s Flues & Flashings components and is suitable for both new installations and upgrades of existing vertical flue systems.
- Connects boiler flue to vertical roof terminal
- Suitable for 60/100mm concentric flue systems
