Flue Options
The
new CSI 85b 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.
Normally supplied with a 1 metre standard horizontal flue kit, this
can be extended to 2.5 metres if required, or 3.5 metres vertical (maximum
without bends).
Alternatively there is a 125mm (concentric) flue system that allows
greater flexibility. Eccentric flue ducting is ideal for covering long
distances and when used with a special Ravenheat connector this can
be extended up to 12 metres air intake/exhaust.
