Maintenance - Beretta BV 120 Installer Manual

Maintenance

The equipment is fitted with a drain tap (SC) with a cap to guard
against it being opened by accident, to facilitate maintenance
and emptying operations.
To drain the boiler, unscrew the safety cap and screw the hose
fitting supplied in place. Use the lever on the tap to open it.
SC
The boiler is fitted with an inspectionable anode (AN) that
protects the boiler itself against corrosion.
We therefore recommend inspecting this anode every year.
AN
To check the degree of consumption of the anode:
- Remove the cover (C) by unscrewing the relevant fixing
screws.
- Unscrew the red cap on top of the anode.
C
If water comes out, this means that the anode is worn and must
be replaced:
- Disassemble the anode, using a CH 26 spanner.
- Replace the anode with a new one.
- Fit all the components again, following the instructions in
reverse order.
Remember that any corrosion that occurs when the anode has
been worn away completely is not covered by the guarantee.
After each inspection, check that the anode inspection cap
is closed.
To clean the internal parts of the boiler:
- Empty then boiler.
- Remove the cover (C) by unscrewing the relevant fixing
screws.
- Remove the sensor or thermostat bulb from the housing.
- Use a CH 17 spanner to unscrew the fixing bolts for the flange
and pull it out.
- Remove the gasket.
