4.1

CONNECTION OF THE STOVE TO THE CHIMNEY

The connection to the stove for the smoke evacuation must be done with rigid aluminized steel pipes or stainless steel pipes.
It is forbidden the use of flexible metallic pipes or fibre cement pipes because they damage the safety of the connection because they are subject to
EN
jerks and breaks, which causes smoke looses.
The chimney must be fixed hermetical to the smoke outlet of the stove. It should be rectilinear and with a material that supports high temperatures
(minimum 400ºC). It can have a maximum inclination of 45° whereby excessive deposits of condensation produced in the initial stages of ignition and /
or excessive soot formation is avoided. Moreover, it avoids the slowing down of the smoke when it comes out.
The lack of sealing of the connection may cause the malfunction of the equipment.
The internal diameter of the connection pipe should correspond to the external diameter of the chimney of the equipment. This service is assured by the
pipes complying with DIN 1298.
4.2

CHIMNEY COWL

The chimney draft also depends on the chimney cowl.
The chimney cowl should assure the smoke discharge even during windy days, having into account that it must exceed the top of the roof.
(1) Industrial chimney of
prefabricated elements
that allow a good smoke
extraction.
The chimney cowl must comply with the following requirements:
• It must have the same interior section of the stove.
• It must have an usable exit section that is two times the one of the interior of the chimney.
• It must be constructed so that the rain, snow or any other objet do not enter inside.
• It must be easily accessible in order to do servicing and cleaning tasks.
It the chimney cowl is metallic, due to its own design adapted to the diameter of the pipe, the smoke discharge is assured. There are different models of
metallic chimney cowl, fixed, anti-return, and rotary or extractor.

5. OUTSIDE AIR INTAKE

For the proper operation of the stove, it is essential that there is air enough for the combustion and re/oxygenation of the environment where it is
installed. In the case of houses built under the requirements of "energy efficiency" with a great degree of air tightness, it is possible that the air intake
is not guaranteed *the fitter must assure compliance with the Technical Building Code. This means that the air must be able to move for the combustion
through some openings connected to the exterior, even when doors and windows are closed. Moreover, it must comply with the following requirements:
• It must be placed in so that it cannot be obstructed.
• It must be connected to the environment where the equipment is installed and it must be protected by a grate.
• The minimum area of the outlet should not be less than 100 cm2. Check regulations on this issue.
• When the air flow comes through openings that are connected to the exterior of adjacent environments, it is important to avoid air intakes in
connection with garages, kitchens, toilets, etc.

6. FUELS ALLOWED/NOT ALLOWED

The fuel allowed is wood. Use only dry firewood (max. moisture content 20%, which corresponds to firewood that was cut two years ago). The length of
the logs will depend on the model (you can check the technical features of this manual). Compressed wood briquettes must be used carefully in order to
avoid harmful overheating of the equipment because they have a high calorific power.
The wood used as fuel must be stored in a dry place. Damp firewood has approximately 60% of water. Therefore, it is not suitable to be burnt because
it makes the ignition more difficult due to the fact that the heats is used to vaporize the water. Moreover, the moisture content has also the disadvantage
that, when the temperature is lower, the water condense in the fireplace and the chimney. This causes the soot accumulation and condensation, with the
consequent risk of fire.
Among others, it is not allowed to use> coal, barks and panels, damp firewood or with paint or plastic materials. In these cases, the
warranty of the stove shall terminate. It is forbidden to use waste and it would damage the equipment.
Paper and cardboard should only be used during the ignition.
Below is an instructions table about the type of firewood and the quality for the combustion.

(2) Traditional chimney. The proper
exit section must be, at least, two
times the interior
section of the chimney, the best is
2.5 times
3) Chimney with interior cone
smoke deflector
