The NB56kWi internal flue diverter (black UV resistant PVC) is a flue accessory kit that allows you to move the flue terminal position up and away from the air intake by up to 1.5 m*.
It is designed for when a traditional terminal cannot be installed due to the flue being a nuisance or due to flue restrictions. It works in conjunction with the horizontal flue terminal, part FFP100HKIT.
Suitability
INFINITY NB56kWi / N56kWi internal water heaters
* If you don’t need to extend the full 1.5 m you can just use the connecting pipe
