Evacuation duct
It is recommended that a separate smoothwalled evacuation duct should be connected to each
machine, providing the least possible resistance to air.
Check that the shaft flow is at least twice the capacity of the gas exchanger draught
accelerator.
•
Draught accelerator maximum flow rate with no pressure : 180 m³/h.
•
Maximum pressure available with no flow : 23 mm H
2
O.
•
Maximum admissible head loss on evacuation : 15 mm H
2
O at point (
P
).
•
Average temperature of exhaust coming out of the gas exchanger : 140 °C.
Provided an upper
ventilation of 7 dm²
and a
lower one of 14 dm²
in your laundry.
These conditions are absolutely essential for the correct working of the machine.
For gas heating, the required combustion fresh air supply should be not less than 2 m
3
/h per
kW, either 50 m
3
/h minimum for 230 or 340 machine.
Installation of the chemney regulator
For a correct running of the installation, this
chimney regulator must always have its axle
of rotation of his flap perfectly horizontal.
The adjustment toothed wheel has to be
positioned on the maximum, mark no 10,
