The CSI 120 Low Nox boiler is a product with extremely low levels of Nox, well below UK standards. We believe this is one of the smallest most competitive boilers on the market. It measures only 700 x 400 x 300mm, offers a high output and not only that, it comes with a 3 year guarantee.
Flue Options
The new CSI 120 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, depending on the customer’s requirements.
A one metre standard horizontal flue kit is supplied separately; this can extend 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.
See installation manual for all flue options.
