2.6 BOILER SHUTDOWN
For complete boiler switch-off, press the “off”
button, disconnect the omnipolar 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.
2.7 RESTORING CENTRAL HEATING
SYSTEM PRESSURE.
Periodically check the system water pressure.
The boiler pressure gauge should read a pressure
between 1 and 1.2 bar.
If the pressure is below 1 bar (with the circuit cool)
restore normal pressure via the filling cock located
in the lower part of the boiler (Fig. 2-2).
N.B.: close the filling cock 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 as-
sistance from an authorised company.
If frequent pressure drops should occur, ask an
authorised company for assistance to eliminate
the possible system leakage.
2.8 SYSTEM DRAINING.
To drain the boiler, use the special draining
valve (Fig. 2-2).
Before draining, ensure that the filling valve is
closed.
2.9 ANTIFREEZE PROTECTION.
The boiler has an anti-freeze function that
switches on automatically when the tempera-
ture falls below 4°C (standard protection to
minimum temperature of -5°C). In order to
guarantee the integrity of the appliance and the
domestic hot water heating system in areas where
the temperature falls below zero, we recommend
protecting the central heating system with anti-
freeze liquid and installing the the Immergas
Anti-freeze Kit in the boiler (Par. 1.3). 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 car-
ried out with suitably treated water to eliminate
hardness that can cause lime-scale.
2.10 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.11 DECOMMISSIONING.
In the event of permanent shutdown of the
boiler, contact an authorised company for the
suitable procedures and also ensure the electri-
cal, water and fuel supply lines are shut off and
disconnected.
Error
Code
Anomaly signalled Cause Boiler status / Solution
43
Block due to loss of
continuous flame
signal
This occurs if the ''Flame signal loss'' error occurs 6 consecutive times
in 8.5 minutes.
Press the Reset button (1).
44
Block for maximum
time, partial gas
valve opening
This occurs if the gas valve remains open for longer than required for
normal operation, without the boiler switching on.
Press the Reset button (1).
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Technical After-Sales Service).
