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 metre 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. Some examples are given below.
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.
