3.5 Flexible Flue Components

At Elco Heating Solutions we can offer a flexible flue solution for when the flue
gas system needs to be routed through an existing chimney/void such as in listed
buildings where amendments to the building layout cannot be made.
We have a simple starter kit that has been assembled to make it easier when
selecting the required items. The starter kit includes a chimney cover, bottom
bend and support, 5 spider brackets, flexible and rigid couplings and the
installation tool.
Adding this kit to the appropriately sized flexible flue liner and the concentric/PPs
flue from the boiler, this gives you a kit that will allow you to take the flue gas to
the desired termination location as per the image.

The image on the left is an example
installation of a flexible flue solution where the
air is being taken in via the chimney cover and
then down through the chimney into the
150mm connection on the wall plate, where it
will then be taken into the boiler via concentric
flue pipe.
The flue gas is being taken from the boiler
through concentric flue pipe to the wall plate,
where it is connected to the flexible flue and
taken out through the flexible pipe to the
termination at the chimney cover.
This solution allows the boiler to operate as a
room sealed device taking combustion air from
the brick chimney which is ventilated to allow
air to be taken from outside. We recommend
that the chimney is swept prior to installation to
reduce the risk of dirt to be drawn into the
boiler.
This is mostly used in older buildings where
modification of the building is prohibited.
