2.4 FLUE GAS GAS EXHAUST INSTALLATION
2.4.1 PREAMBLE
The indications contained in this chapter refer ex-
pressly to the European standards EN13384 - EN1443
- EN1856 - EN1457.
IMPORTANT!! Have a qualied installer check
the eciency and condition of the ue, compliance with
national and local standards for ue gas ducts and the use
of appropriate materials.
The information above is purely indicative for correct
installation. Zantia is not liable for installation.
2.4.2 FLUE
Every appliance must have a vertical duct called ue to re-
lease combustion exhaust gases outside the home via natural
draught. The ue must meet the following requirements:
• It must not be connected to any other replace, boiler, or
range hood of any kind.
• It must be kept at safe distance from combustible or am-
mable materials by means of air gap or suitable insulation.
• Its internal cross-section must be even, possibly circular:
square or rectangular cross-sections must have rounded
edges with a radius not below 20mm; maximum side ratio:
1.5; walls as smooth as possible and without any narrow-
ing; curves must be even and without discontinuity, axis
deviation must not exceed 45°.
• Every appliance must have a ue with a 100 mm diameter
and whose height must not be below that declared (see
table 1), even if the product provides for a output diam-
eter of 80 mm.
• Never use a boiler and a boiler, a replace and a boiler, or
a boiler and a wood burning stove in the same room, since
the draught of one appliance can damage the draught of
the other. Moreover, collective ventilation ducts are not al-
lowed, since they can create negative pressure in the place
of installation, even when installed in adjacent or commu-
nicating rooms.
• IT is prohibited to create xed or moving openings on the
ue to connect appliances other than the one it is serving,
• IT is prohibited to pass other air adduction ducts or tubes
through the ue, even if it is oversized.
• IT is advisable that the ue is tted with a solid mate-
rial and condensate collection chamber, located under
A
the inlet, in order for it to be easily opened and in-
spected from the airtight door.
• When using ues with parallel outlets, it is recommended
to rise the bracing pipe by one element. (g. 4).
g. 4 allowed and forbidden ue gas exhaust installation meth-
ods
• For the installation of products with top ue gas ex-
haust, it is mandatory to use the ue gas kit requiring
installation of the upright pipe which remains inside
the boiler.
2.4.3 CHIMNEY
The top of the ue must be provided with a device, called
chimney, which facilitates releasing combustion products
into the atmosphere. The chimney must meet the following
requirements:
• Have an internal cross-section and shape equivalent to
that of the ue.
• The outlet cross-section must be at least twice the cross-
sectional area of the ue.
• The chimney which exits the roof or which remains in con-
tact with the outside (for example for an open slab) must
be covered with bricks and anyway well insulated. Be built
in a way to prevent penetration of rain, snow, and foreign
bodies into the ue and so that in the presence of wind in
any direction and inclination, discharge of the combustion
products is still assured (wind barrier chimney).
• The chimney must be positioned in such a way as to en-
sure proper dispersion and dilution of combustion prod-
ucts outside the backow area. This area has dierent sizes
and shapes depending on the inclination angle of the roof,
