Whenever possible, build your chimney
inside the house; this will provide better
draw, lower creosote accumulation and
a longer life.
The advantages of brick chimneys
include:
a) Fumes cool off more slowly inside
the chimney due to the mass of
bricks and tiles.
b) As bricks accumulate heat, the
house keeps warm longer after the
fire is put out.
c) It can be built to the specific
requirements of each person.
d) If well built, it will be more
resistant to fire than metal chimneys.
Brick chimneys must be well lined to
prevent the fumes from losing
temperature.
They must be built with materials that
support
high
temperatures
and
corrosion.
They may be round, square...., what
matters is their size.
Brick chimneys for the Hergóm cooker
must comply with the measurements
indicated in the chapter on TECHNICAL
DATA.
The advantages of metal chimneys
include:
a) Easy installation.
b) It is possible to change the
direction of the chimney slightly,
which provides greater flexibility
when deciding where the chimney
should be installed.
c) Curved joints can be used, which
eliminates acute angles that have a
negative effect on draw.
4.- Connection to the chimney
Bends and horizontal sections, which
have a negative effect on draw and
favour the formation of creosote and
soot, must be avoided in the vertical
section of the chimney.
It is very important
to seal the ring -
elbow - pipe joint using refractory putty,
plaster or some other appropriate
material to prevent air from seeping in.
The connection of the pipes that form
the chimney, in the case of metal pipes,
must be sealed during assembly with
the "male" coupling facing downwards.
This will prevent any creosote that
forms inside from leaking out.
This advice must be followed whenever
wood or coal is used as fuel.
5.- Some rules
We shall now explain a number of rules
that should be followed when building a
chimney:
a) Use resistant, fireproof materials.
Do not use cement asbestos pipes in
the first 2-3 metres.
c)
b) Choose the most vertical route
possible. Do not connect several
devices to the same chimney.

c) The conduit should not come to an
end near buildings and must be
higher than the nearest obstacle if
there is another building nearby.

d) Install the conduit in an area
as protected from the cold as
possible.
If
possible,
the
chimney should be built inside
the house.
