The vertical roof terminal kit from Navien is a component used to safely terminate a vertical flue system through a roof. This flue is essential for venting exhaust gases from the boiler directly up through the roof of a building. The flue ensures that the gases are expelled safely and effectively into the atmosphere, preventing them from accumulating inside the building and posing health risks.

The purpose of a vertical roof terminal kit is to facilitate the safe and efficient exit of exhaust gases, while also ensuring that the roof penetration is sealed against the elements. This is crucial for maintaining the safety and integrity of both the flue system and the building structure.

Complete with vertical adaptor.
