2.2 Pipe connection
Aduro H5 leaves the factory with the flue outlet mounted on the top. If you require the flue outlet on the back,
remove the round circle from the rear cover at the upper rear of the stove and then exchange the exhaust
connector (located on the top outlet above the stove) with the cover plate (that covers the rear outlet). The
top outlet is finished with the plate that lies in the ash pan. We recommend that you place a thin gasket
between the flue pipe and exhaust branch. A flue pipe with an internal diameter of 150 mm should be used
for Aduro stoves. Aduro H5 is tested and approved for use with an uninsulated fluepipe of minimum 100 cm.
2.3 Connection to a brick chimney
If the stove is being connected to a brick chimney, the rear outlet should be used, or a curved flue pipe via
the top outlet. After measurement, a hole is made in the chimney in which the pipe sleeve is placed and
fireplace mortar is used to seal it in place. The stove is placed in position and the flue pipe is put in place. A
thin gasket is placed between the flue pipe and the pipe sleeve to seal the joints. The flue pipe should
protrude into the pipe sleeve but must not block the opening in the chimney (see the illustration below).
The Aduro H5 can be connected to a chimney to which other heat sources are connected.
2.4 Supply of combustion air
All wood burning stoves need constant supply of air to ensure a
clean and efficient combustion. This is often a problem in modern
energy-efficient houses that are very tight. The amount of air
needed for combustion is 25 m3/h. The Aduro H5 can partially be
provided with combustion air (for the pellet combustion, primary
and secondary air) through a channel from the outside which is
connected to the connecting pipe behind the stove. Aduro H5
uses air from the air-wash system for the wood combustion.
The connecting pipe has an external diameter of 78 mm, to
which you need a pipe with a diameter of 80 mm. If the pipework
is more than 100 cm, or if there are bends on the tube, the
resistance in the pipe increases significantly. Negative pressure
outside on the sheltered side of the house can also affect the resistance of the pipe significantly. In these
situations, the pipe should have a diameter of minimum 100 mm. It may also require a stronger chimney
draft, which you can achieve by installing a stronger fan (Aduro Air Booster) or even better: an Aduro
DraftOptimizer. You can easily test the resistance in the pipe by opening a window close to the stove,
disconnect the external air supply and then light up the stove. If the combustion looks different than before,
