Filling the installation:
The network must be properly drained. This will be more effective if the boiler
is filled slowly, while keeping:
• the manual drain of the exchanger open,
• the safety valve open.
When these two parts discharge a continuous flow of water that is free of
bubble, close them and stop filling.
After filling with water:
• Check the water pressure on the pressure gauge (not included). This must
be a maximum of 4 bar when hot and a minimum of 1 bar when cold.
• Check that the boiler and its installation are completely bled (check the
boiler levelling with a spirit level).
Condensate removal:
Removal to the drains, via a drain hopper, using a P.V.C tube (minimum
diameter 32 mm) is mandatory because the condensates are acid and thus
aggressive (pH between 3 and 5).
Use a sufficient slope of the order of 3% to ensure correct flow of the
condensates.
Neutralise these condensates before removal according to the current
regulations.
