CHIMNEY COWL

The chimney draft also depends on the chimney cowl. Therefore, in case of an artisanal chimney cowl, it is indispensable the exit section
would be twice the inside section of the smoke duct. The smoke throughout will be assured even in presence or air (see drawing D13).
The chimney cowl must comply with the following requirements:
(1) Industrial chimney of
prefabricated elements
that allow a good smoke
extraction.

• 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, 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.
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.
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 (40mm or 50mm 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. 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.

MOUNTING CHARACTERISTICS

The models Elsa, Brenda and Brenda-E have the smoke exit only in the rear (see drawing D14).
On the other hand, in the Paula model, you have the option to connect the exhaust pipe to the stove by its side (lateral
outlet), it will be enough to lightly tap the partly perforated on the side cover and connect the pipe to the extractor using
an elbow of 90º and 80 mm of diameter. Subsequently, connect the rest of the installation (registration T, converter,
straight section, etc).
In every single case, do not forget to follow the safety distances of the stove and the pipe with the walls (see section
"safety distances").

IN CASE OF INSERTING THE MODEL BRENDA-E ...

In case you choose to insert this model, you must take into account the following advices:
- It is advisable to remove the stove legs, and adapt it some scroll wheels, so that you can move the stove easily, if necessary.
- It is compulsory for the installer to provide an easy disconnection in the smoke exit so that the stove can be removed in case of
maintenance or repair works.
- It is compulsory to equip the stove with the primary air intake for the right combustion, see section 5.4 of this manual.
- In all cases, leave a safety space between the stove and the side walls and top of the coating, at least 3 cm.
- Verify that the lining walls located around the stove can withstand the 60-70ºC temperature generated by the stove. Consider the

proper exit section must be,
at least, two times the interior
section of the chimney. The best
is 2.5 times.

temperature reached by the smoke exit pipes in the case of running
inside the coating.
- Do not disassemble the stove panels, in other words do not
disassemble the chambers of the stove, because they are covered with
thermal insulating material, which will help to transmit less heat to the
walls of the coating.
- It is essential that the area between the upper part and
both sides of the stove (sides and rear) is constantly ventilated. For this
reason, it is necessary to allow air to enter to the bottom of the coating
(fresh air inlet) and an outlet at the top (hot air outlet) above the stove.
With this, we are establishing a natural convection circuit. Each of
these openings must be free and must not be blocked, with a minimum
surface area of at least 3 dm2 (for example, a vent of 30 x 10cm).
