2.7 BOILER SHUTDOWN.
Switch the boiler off by pressing the “
” button,
disconnect the onmipolar switch outside of the
boiler and close the gas cock upstream from the
appliance. Never leave the boiler switched on if
left unused for prolonged periods.
2.8 RESTORE HEATING SYSTEM
PRESSURE.
Periodically check the system water pressure.
The boiler manometer should read a pressure
between 1 and 1.2 bar.
If the pressure falls below 1 bar (with the circuit
cool) restore normal pressure via the valve located
at the bottom of the boiler (Fig. 2-8).
N.B.:
close the valve after the operation.
If pressure values reach around 3 bar the safety
valve may be activated.
In this case, remove water from an air vent valve
of a radiator until 1 bar is reached or ask for
assistance from an authorised company.
If frequent pressure drops should occur, ask an
authorised company for assistance to eliminate
the possible system leakage.
2.9 DRAINING THE SYSTEM.
To drain the boiler, use the special draining
valve (Fig. 2-8).
Before draining, ensure that the filling valve is
closed.
2.10 ANTI-FREEZE PROTECTION.
The “Victrix Superior 32 2 ErP” series boiler
has an anti-freeze function that switches on
automatically when the temperature falls
below 4°C (standard protection to minimum
temperature of -3°C). All information relative to
the anti-freeze protection is stated in Par. 1.3. In
order to guarantee the integrity of the appliance
and the domestic hot water heating system in
zones where the temperature falls below zero,
we recommend the central heating system is
protected using anti-freeze liquid and installation
of the Immergas Anti-freeze Kit in the boiler. In
the case of prolonged inactivity (second case),
we also recommend that:
- the electric power supply is disconnected;
- the heating circuit and boiler domestic water
circuit must be drained. In systems that are
drained frequently, filling must be carried
out with suitably treated water to eliminate
hardness that can cause lime-scale.
2.11 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.12 DECOMMISSIONING.
In the event of permanent shutdown of the
boiler, contact an authorised company for the
suitable procedures and also ensure the electrical,
water and fuel supply lines are shut off and
disconnected.
