b / APPLIANCES CONNECTED TO A FLUE MANIFOLD SYSTEM
Very important :
The flow extracted on each appliance must be equivalent.
The installer will have to comply with the official texts of each country concerning mechanical
evacuation and will have to get information from the competent national organisations about :
1) how to balance the network.
2) the controls and the different securities to put into operation.
Schematic diagram
It is necessary to take off the grille of flue outlet from the appliances and to replace it by a
connection piece
. Connect the top of the dilution piece to the collector with a flue tube and
check that the connection of this duct is made on the side of the main duct (collector) and not
from below.
Place the dilution piece on the tube coming from the appliance and fix the 3 fixing
parts by the means of screws or rivets.
Do not take off the screwed rod which is used as a thrust.
Plan for that the air entry in the building is a minimum of
10m3/h per kW.
