3. - Options
If you are going to build a chimney for your Built-in Fireplace EQH, you have two alternatives:
a) Brickwork chimneys.
b) Metal chimneys.
Studies have reached the conclusion 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 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.
Brickwork chimneys for the Built-in Fireplace EQH 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 fireplace should be installed.
c)
Curved joints can be used, which eliminates acute angles that have a negative effect on draw.
4. – 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.
b) Choose the most vertical route possible. Do not connect several devices to the same chimney.
