HE 150(T) Low NOx Technical Guide
small logo


Flue Options
The new HE150T Low NOx can be fitted with either a 100mm standard (concentric), a 125mm flue duct or a twin (eccentric) flue duct, which can be installed either vertical or horizontal. A 1 metre standard horizontal flue kit is supplied separately, this can be extended to 8 metres if required, or 13 metres vertical (maximum without bends). Alternatively there is a 125mm (concentric) flue system that allows greater flexibility (26 metres).

Eccentric flue ducting is ideal for covering long distances and when used with a special Ravenheat connector this can be extended up to 43 metres air intake/exhaust.
