The way your Insert Fireplace is installed will
decisively affect safety issues and how it works.
It is important to install the fireplace correctly.
In order to ensure your insert fireplace has been
installed correctly, it should be installed by a professional.
Your insert fireplace heats by means of radiation,
heating walls, ceiling... directly and by forced air
convection, thanks to its internal fan.
2.1
HOT AIR.
TOP GRILLE AIR FLOW
This is the STANDARD air exit. Air enters through
the lower section, "A", and the internal fan forces the
hot air through the top section "B".
AIR FLOW THROUGH THE HOOD
This option is compatible
mentioned above.
Brick hoods must include holes at the bottom and at
the top. These gaps can be covered by ornamental
grilles to facilitate the flow of air. Cold air enters
through the lower section, "C" and exits through the
higher section "D" (take into account that your Insert
Fireplace provides most of its heat by convection). If
the ventilation holes in the hood are not large
enough, the device may be damaged if it is unable
to dissipate the heat.
IMPORTANT! The minimum gap recommended for
air input is 200cm² of free air passage through the
grille.
(The air input grilles in the hood must be located
in such a way that they cannot be blocked).
2.2
CHIMNEYS.
The way the insert fireplace works depends on:
d) The chimney.
e) How it is used.
f) The quality of the fuel used.
What is the "chimney draw"?
The tendency hot air has to rise generates the
chimney effect.
- Wind speed. Usually, sustained strong winds
increase chimney draw but stormy winds have a
negative effect.
- External temperature. The colder it is outside,
the greater the chimney effect.
- Atmospheric pressure. The chimney effect is
usually poor on rainy, damp or stormy days.
- Intensity of the fire. The hotter the fire, the
stronger the chimney effect.
- Cracks in the chimney, badly sealed or dirty
doors, air entering through pipe joints, other devices
connected to the chimney.... may have a negative
effect on chimney draw.

2.2.2. Creosote formation and cleaning.
When wood burns slowly, it produces tar and other
organic fumes in the smoke conduits. When combined with
a damp atmosphere, they form creosote. Creosote fumes
may condense if the chimney walls are cold. If it catches fire,
extremely tall fires may be caused. Any accumulation of
creosote must be eliminated. It is very difficult to know the
exact moment when the chimney should be cleaned. The
safest way of ensuring that the chimney of your fireplace is
creosote free is by performing a visual inspection.
Consequently, we recommend building installations that are
easy to access for inspection purposes.
2.2.3. Options.
If you are going to build a chimney for your insert
fireplace, you have two alternatives:
c) Brickwork chimney.
d) Metal chimney.
Studies have displayed that there is no great difference
in performance between metal and brick-cement chimneys.
You will have to choose one or the other.
Whenever possible, build your chimney inside the
house; this will provide better draw, lower creosote
accumulation and a longer life.
THE ADVANTAGES OF BRICKWORK CHIMNEYS
INCLUDE:
e) Fumes cool off more slowly inside the chimney due
to the mass of bricks and tiles.
f) As bricks accumulate heat, the house keeps warm
longer after the fire is put out.
g) It can be built to the specific requirements of each
person.
h) If well built, it will be more resistant to fire than metal
chimneys.
Brickwork 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 internal
diameter.
Brickwork chimneys for the insert fireplace must
comply with the measurements indicated in section
TECHNICAL DATA.
THE ADVANTAGES OF METAL CHIMNEYS INCLUDE:
e) Easy installation.
f) It is possible to change the direction of the chimney
slightly, which provides greater flexibility when deciding
where the chimney should be installed.
g) Curved joints can be used, which eliminates acute
angles that have a negative effect on draw.
h) Curved joints can be used, which eliminates acute
angles that have a negative effect on draw.
