empty the water in the boiler (see
section 8.6);
unscrew the top anode and check for
any corrosion; if more than 30% of the
anode surface is corroded, replace the
anode;
repeat for the bottom anode.
The anodes have a gasket; to avoid water
leakages, use an anaerobic sealant for
compatible threads for use in heating and
sanitation systems. The gaskets should be
replaced both during checks and when
replacing anodes with new gaskets.
8.6
Emptying the boiler
If the boiler is not used, especially in low
temperatures, it is good practice to empty
the water inside the boiler.
For this appliance, simply disconnect the
water inlet connector (see section 5.4).
Alternatively, when setting up the system,
install a drain valve with a hose connector
coupling.
NOTE: remember to empty the
system when temperatures are
low to prevent freezing.
