Loss of flame signal.
This occurs when the boiler
is ignited correctly and the burner flame switches
off unexpectedly; a new attempt at ignition is
performed and if normal conditions are restored,
the boiler does not have to be reset (this anomaly
can be checked in the list of errors “P19” present
in the “M1” menu). If this phenomenon occurs
frequently, contact a qualified technician for
assistance (e.g. Immergas After-Sales Technical
Assistance Service).
High ΔT. If the board detects a sudden and unex-
pected rise in ΔT between the system flow probe
and return probe, the boiler limits the burner
output to prevent damaging the condensing
module; when the correct ΔT has been restored,
the boiler returns to normal operation. Make sure
there is water circulating in the boiler, that the
pump is configured according to system require-
ments and that the return probe works properly.
If this phenomenon occurs frequently, contact a
qualified technician for assistance (e.g. Immergas
After-Sales Technical Assistance Service).
Burner power limitation. In the event that the
boiler is blocked, the boiler reduces the power
supplied to prevent damaging it; a qualified
technician must be called (e.g. Immergas After-
Sales Service).
High temperature block on return probe.
This
occurs when the heat exchanger return circuit
reaches too high a temperature. Make sure that
water circulates properly in the boiler and that
the three-way valve works properly. To elimi-
nate it, the Reset button (C) must be pressed. If
this phenomenon occurs frequently, contact a
qualified technician for assistance (e.g. Immergas
After-Sales Technical Assistance Service).
Signalling and diagnostics - Display of the
Remote Controls (Optional). During normal
boiler functioning the remote control display
shows (CAR
V2
remote control or Super CAR re-
mote control) the room temperature value; in the
case of malfunctioning or anomaly, the display of
the temperature is replaced by the relative error
code present in the table (Par. 2-6).
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 contact a professional technician
for assistance.
In the event of frequent pressure drops, contact
qualified staff for assistance to eliminate the
possible system leakage.
2.9 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 TOP 32 X E” 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;
- fully empty the heating circuit. 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.
