Installation Advices
* This type of unit should be installed in a well-ventilated area. Any air intake grilles
should be placed in locations that are not liable to become blocked, so that the place of
installation has sufficient air in the order to avoid a poor draft;
* The combustion air enters the unit through a system that controls the burn intensity.
This flow should be kept clear at all times;
* The ventilators that extract air from the room, must not be used;
* Use of this unit at the same time as other heating devices that require an air supply
may necessitate additional air inlets. The installer should assess the situation in light of
total air flow requirements;
* For your unit to function in normal conditions the combustion gas draft must create a
draught of 12 Pa one metre above the throat of the flue. If this is not achieved in your
chimney, your wood-burning cooker may not work properly, for example, by throwing
smoke outdoors or consuming excess wood. For proper installation, at least 78,7 inches
(2 metres) of metal rigid flue tube with the same diameter as the unit's smoke outlet
should be fitted vertically above the unit. If this not achieved on your chimney, your unit
might not function correctly, leading to smoke to the exterior or excess of wood
consumption. After this section, sections of tubing with a maximum angle of 45° may be
used (in this case the chimney should be cleaned once a year); the following figure
illustrate correct and incorrect angles for installing a bend.

* A single-walled tube installed on the outside of a building or in areas subject to
thermal variations, results in the condensation of water vapour in the combustion gases.
Instead, use of a double-walled, insulated tube is recommended;
* The tube unions must be well sealed to prevent air entering through possible gaps;
