Filling the installation:
The system must be fully vented to remove all air. This will be more effective if
the boiler is filled slowly when cold, while keeping:
•
the manual drain of the exchanger open,
When these two parts discharge a continuous flow of water that is free of air,
close them and stop filling.
INFORMATION: Limit hydraulic noise by carefully purging the installation, limiting
water speeds, and letting the pipes expand freely.
IMPORTANT:
If there is a risk of freezing, start up the installation then leave the
boiler powered (refer to the Navistem B3100 manual). If the boiler
cannot remain powered, take the necessary precautions against
freezing (draining may be a solution).
After filling with water:
• Check the water pressure on the pressure gauge (not included). This must
be a maximum of 4 bar for 40 to 70 kw models or a maximum of 6 bar for 80
to 150 kW models when hot, and
a minimum of 1 bar when cold
.
• Check that the boiler and its installation are completely free of air (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
condensate.
IMPORTANT:
Neutralise these condensate before removal according to the current
regulations.
