3.3 Assembly of the duct components.
Duct components and pipes
For the assembly of the duct pipes the use of non-flammable materials, resistant to the flammable
products and condensation is obligatory. The assembly must be performed in such a manner so
it guarantees the airtight sealing and prevents condensation. If possible, avoid adding horizontal
sections. Direction shift is done by using knee joints with a max angle of 45˚.
For heating devices equipped with a smoke ventilator, i.e all of the “MARELI” boilers, the follow-
ing instructions must be observed:
Chimney
The chimney or the duct component must conform with the
following requirements: to be airtight, waterproof and prop-
erly insulated, to be constructed with materials resistant to
the normal mechanical wear and to the heat coming from the
combustion products and condensation.
•
To be kept away from flammable materials.
The recommended chimney draft at work - from 12-20 Pa.
• Horizontal sections must have a minimum incline
of 3° upwards;
• The length of the horizontal sections must be as
short as possible, but without exceeding 3 m;
• More than four direction shifts are forbidden,
including the cases where a T-shaped element is
used;
• The duct components must be airtight and to be
insulated if extending outside the premises in
which the fireplace is installed;
• The duct components must allow a soot cleaning;
• The duct components must have a constant sec-
tion. A section change is allowed only in the
chimney joint;
