2.7 BOILER SHUTDOWN
For complete boiler switch-off, press the “off”
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. 2-2).
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 possible
system leakage.
2.9 DRAINING THE SYSTEM.
To drain the boiler, use the special system
draining valve (Fig. 2-2)
Before draining, ensure that the system filling
valve is closed.
2.10 ANTI-FREEZE PROTECTION.
The boiler has an anti-freeze function that
switches on automatically when the temperature
falls below 4°C (standard protection to minimum
temperature of -5°C). All information relative to
the anti-freeze protection is stated in Par. 1.4. 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 professional staff for the procedures and
ensure that the electrical, water and gas supply
lines are shut off and disconnected.
