Direct emission into the atmosphere

Natural draught boilers can discharge combu-
stion products directly into the atmosphere
using a duct, which goes through the outside
walls of the building, connected to a flue
exhaust terminal.
The exhaust duct must also comply with the
following requirements:
-

the sub-horizontal part inside the building
must be as short as possible (no more than
1 m);

-

for boilers with vertical discharge, such as
boilers 

IVEN 04 CTN 24 F, IVEN 04 RTN

, there must be no more than 2 direction

changes;

-

it must receive the discharge from a single
boiler;

-

the part going through the wall must be
protected by a sheath duct; the part of the
sheath duct facing the inside of the buil-
ding must be sealed and the part facing
outwards must be open;

-

the final section, on which the draught ter-
minal will be fixed, must protrude from the
wall of the building for a length of at least
twice the diameter of the duct;

-

the draught terminal must overlap the con-
nection to the boiler by at least 1.5 m (see
fig. 8).

DIMENSIONALS FOR CONNECTING FLUE GAS  DUCT

WARNING:

The boiler is fitted with an automatic safety
reset device as protection against spillage of
combustion products inside the building.
If this device is activated the boiler will cut off
and a fault will be indicated by the lockout
(warning light 

G

) fig. 35.

After the cooling down of the smoke thermo-
stat it will be possible to restart the boiler by
pressing the reset button

It is absolutely forbidden to
by-pass the smoke thermo-
stat.

If the boiler cuts off regularly, it

is necessary to ask a technician for a check
of the flue gas exhaust duct. This duct may
be obstructed or may be unsuitable for the
discharge of flue gas into the atmosphere.
