Brick chimneys must be lined on the outside of the dwelling to prevent smoke cooling.
They must be built in materials that withstand high temperatures and corrosion.
Make sure the chimney is clean and operates correctly, as this will prevent losses of
draught and the formation of creosote.
Make sure the chimney is of the right size
and that it is not too high.
A draught valve must be installed if it
is too high.
If your brick chimney has a larger cross -
section than that recommended by the
manufacturer of the appliance, it would be
best to install another metal chimney of
suitable proportions inside in order to avoid
problems with operation and creosote
accumulation.
In this case it would be best to seal one of
the ends of the chimney against the pipe to
prevent the formation of currents that could
cool the chimney (see Fig. - 3).
This seal should be performed at the top to
make use of the heat that is produced along
the whole section of the chimney. In the
same way, it is best to perform a circulation
inside this chamber between the pipes and
the chimney to allow relief and prevent
excessive heat from causing damage in the
walls (cracking etc...). To do this it would be
sufficient to locate and lower and upper grill
(15 x 10 cm) in the chamber. The air will
circulate by natural convection, taking the
hot air from the bottom to the top of the
dwelling.
METAL CHIMNEYS
The advantages of these chimneys are:

They are easy to install.

They enable slight changes in the
direction of the chimney, which gives
more flexibility in the choice of the place where the stove is to be installed.

As there are curved elbows, the sharp angles are eliminated that could make the draught
difficult.
Make sure that all the pipes of the chimney fit well and are completely sealed.

1.2.2 - TYPES OF INSTALLATIONS

When you install the chimney and the accessories, make particularly sure that you respect all
the manufacturer's recommendations for the right distances of the chimney from the
combustible materials, walls and ceilings.
There are basically two ways to install a prefabricated metal chimney:
Interior or exterior installation
