2.3.1 Flue piping in new installations
The easiest way of installing the flue pipe is through a chimney with an aperture of 160 mm straight above
the exhaust connector on the inset. In this case, a straight 2.0 mm flue pipe with an internal diameter of 150
mm of a suitable length should be used. 3 x gasket bands should be placed around the flue pipe, which is
then pushed up into the chimney. The fireplace insert is placed in position and the flue pipe is pulled down
over the exhaust connector.
The fireplace insert can also be fitted with a steel chimney. The steel chimney should be placed directly
above the exhaust connector. We recommend the use of a steel chimney that is self-supporting and fitted
with a telescopic flue pipe. This solution allows you to lift the flue pipe and remove the insert without affecting
the chimney. Remember that the space above the fireplace insert should be sealed off with a horizontally
positioned non-flammable plate. This plate should be installed at least 85 cm below the ceiling. The space
under this plate (above the fireplace insert) should be ventilated as described on the previous page.
If the chimney goes directly down into the fireplace insert without sharp angles or significant bending, a wall
sleeve will usually not be needed. It is also important that there is no edge inside the chimney where soot
can collect.
2.3.2 Flue pipe installation in a large chimney
A chimney that is larger than the flue pipe can be sealed with fixed rockwool batts, that are trimmed so that
they adhere tightly around the flue pipe. The batts should be laid in 3 layers and spread with fireplace mortar
before they are pushed up into the chimney from below. The fireplace mortar will stiffen and fix the batts to
form a floor in the chimney.
2.3.3 If you do not have free access to the chimney and are using flexible piping
The flexible piping should be trimmed to the appropriate length. Please note that the flexible piping should
protrude approx. 10 cm into the pipe sleeve. Then a thin gasket should be placed between the flexible pipe
and the pipe sleeve in the chimney and the flexible pipe should be pushed securely into place in the pipe
sleeve. Adjust with the setting screws until it is in the correct horizontal position.
The fireplace insert can be connected to a chimney to which other heat sources are connected.
