2.8 BOILER SHUTDOWN
Switch the boiler off by pressing the “ ” button,
disconnect the onmipolar switch outside of the
boiler and close the gas cock upstream of the
appliance. Never leave the boiler switched on if
left unused for prolonged periods.
2.9 RESTORING CENTRAL 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
cold) restore normal pressure via the valve located
at the bottom of the boiler (Fig. 2-6).
N.B.:
close the valve after the operation.
If pressure values reach around 3 bar the safety
valve may be activated.
In this case contact a professional technician
for assistance.
In the event of frequent pressure drops, contact
qualified staff for assistance to eliminate the
possible system leakage.
2.10 SYSTEM DRAINAGE.
To drain the boiler, use the special draining
valve (Fig. 2-6).
Before draining, ensure that the filling valve is
closed.
2.11 ANTI-FREEZE PROTECTION.
The “Magis Victrix” series boiler features an
anti-freeze function that lights the burner
automatically when the temperature falls below
4°C (standard protection up 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:
- disconnect the electric power supply;
- the central heating circuit and boiler domestic
hot 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.
2.12 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.13 DECOMMISSIONING.
In the event of permanent shutdown of the boiler,
contact professional staff for the procedures and
ensure that the electrical, water and gas supply
lines are shut off and disconnected.
