ADURO 5.1 Manual De Usuario página 33

If the fireplace insert is to be placed close to flammable material such as a wooden floor or carpet, it must be
placed on a non-flammable base. The floor plate should extend for at least 30 cm in front of the fireplace
insert and 15 cm on each side measured from the opening of the combustion chamber.
The fireplace insert must be installed on a floor with the adequate load-bearing
capacity. If the existing construction does not meet this requirement,
appropriate adaptation measures must be taken (e.g., a load-distributing plate).
2.2 Convection and ventilation
The Aduro 5.1 is built as convection stove. This means that air
from the room circulates between the inner stove and the outer
covering. As a result, the heated air is distributed evenly
throughout the room. In order to fully exploit the energy in the
wood, however, the heat generated around the fireplace insert and
the flue pipe (that connects the fireplace insert to the insulated
chimney) should also be used. The calorific values depend on the
length of the uninsulated flue pipe – initially, the first meter of
uninsulated flue pipe will increase the efficiency by approx. 5 %.
There should be at least 25 mm space around the fireplace insert.
It is important that the space around the fireplace insert, and the
flue pipe is ventilated. There should be ventilation openings of at
least 200 cm2 both below and above the fireplace insert. There are
many ways to create ventilation around the flue pipe. See
illustration.
2.3 Connecting the flue pipe
The fireplace insert can be connected using either flexible piping or regular flue piping. If you use flexible
piping, you must ensure that the piping is designed for flue gas use and can withstand high temperatures.
Flexible piping may only be used in an existing fireplace installation. Therefore, we recommend that you
consult your chimney sweep before using flexible piping. You can use both the top and rear outlets on the
fireplace insert, depending on what suits your installation best. The Aduro 5.1 is supplied ready for fitting the
flue pipe on the top. If the flue pipe is to be fitted on the back, the round circle should be removed from the
rear plate of the fireplace insert. The cover plate (that covers the rear outlet) should then be moved to the top
outlet. A flue pipe with an internal diameter of 150 mm should be used for the Aduro 5.1.
It will usually be easier to use flexible piping if there is not particularly good access to the chimney. If, on the
other hand, you have complete access, we recommend that you use a regular 2.0 mm steel flue pipe.
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
