BOILER SHUTDOWN

Switch the boiler off by putting it in “off ” mode,
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 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 falls below 1 bar (with the circuit
cold) restore normal pressure via the valve located
at the bottom of the boiler (Fig. 1-3).

N.B.:

close the 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.

2.9 SYSTEM DRAINING.

To drain the boiler, use the special draining
valve (Fig. 1-3).
Before draining, ensure that the filling cock is
closed.

2.10 ANTI

FREEZE PROTECTION.

The “Victrix Maior 35 X TT 1 ErP” series boiler
has  an  anti-freeze  function  that  switches  the
burner 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. 1.3. 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 car-
ried 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 electri-
cal, water and fuel supply lines are shut off and
disconnected.

To exit the menu, press the “Info” button (5) up
to the end of the list, or by pressing the “Reset”
button (2) or by waiting for 15 minutes.

With the menu active, the indicator (14) will
alternately show the indication of the parameter
via the letter “d” plus the number of the param-
eter that is being displayed and the value of the
parameter itself.
