CHIMNEY COWL

The chimney draft also depends on the chimney cowl. Therefore, in case of an artisanal chimney cowl, it is indispensable that the exit section is twice the
inside section of the smoke duct. The smoke exit will be assured even in presence or air.
The chimney cowl must comply with the following requirements:
• It must have the same interior section of the chimney.
• 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.

OUTSIDE AIR INTAKE

For the proper operation of the stove or insert, it is essential that there is enough air for the combustion and re/oxygenation of the environment where
it is installed. 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.
The connection tube material can be made in any material (PVC, aluminium, polyethylene, etc.), not necessarily metallic. Consider that inside this duct is
going to pass air at the outside temperature.

ASSEMBLY SPECIFICATIONS ACCORDING TO MODELS

5.7.1

MODELS SLIM9 AND SLIM12

There are two different ways to connect the chimney duct with the SLIM-9 and SLIM-12 models:
- Top exit: it will be enough knocking softly the upper cover that is partially pierced and connect
the ducts to the smoke duct of the extractor on the stove. Do not forget to respect the safety
distance of the stove with the walls (see chapter "safety distance").
- Rear or lateral exit: the pipe will be connected to the smoke duct of the extractor on the stove (vertical) Place a 90º elbow of 80 mm diameter
(to convert the outlet in lateral or rear) and then, place the rest of the installation pipes, for example: converter, "T" with a register cover, elbow,
pipe, etc. Take into account that, with this option the stove will be separated of the wall, at least the diameter duct plus the recommended security
distance (see chapter "safety distance").
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 cm .

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.
The stove is provided with a necessary air intake for the combustion on the back side (40 mm diameter). It
is important this intake is not blocked and to respect the recommended distances to the wall or near items.
It is recommended the primary air intake connection of the stove with the outside although it is not
obligatory with the exception of the Insert 7 model, whose intake is obligatory to connect it at least to the
exterior of the coating to guarantee the correct contribution of primary air to the combustion. This model
includes the primary air pipe that must be connected to the outside.
(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 baffle-plate.
