Direct outside discharge
Natural draught boilers can vent flue gas directly into the atmosphere via a duct which goes through the outside walls of the building
and ends with an anti-wind gust device terminal.
The flue gas exhaust duct is to comply with the following requirements:
•
its sub-horizontal part inside the building must be as short as possible (not longer than 1,000 mm);
• it is not to have more than 2 direction changes;
•
it can host only one single boiler flue gas exhaust system;
• its section, which is passing through the wall is to be protected by a sheath duct; the part of the sheath duct facing the inside of the
building is to be sealed, while the part facing outwards is to be left open;
• its end section, on which the draught terminal is to installed, is to protrude from the wall of the building for a length of a least twice
the diameter of the duct;
•
the terminal must be no less than 1.5 meters above the connection for the flue gas venting duct on the boiler.
•
the connection pipe must be fixed to the boiler hood by means of a screw in the specific
A
hole (see
Fig. 9 Dimensions for connec-
tion to the flue gas system of the open chamber models).
