3.12 FLUE TEST
To define the value to set in the ”flue length” “F0” parameter, de-
tect the parameters during the “flue test”.
Before performing the test, ensure that the condensate
drain trap has been filled correctly and check that there
are no obstructions in the air intake circuit and flue ex-
haust and that the sealed chamber is perfectly closed and
the flue has already been installed.
Once the test has been carried out properly, note the detected val-
ue in the relevant table, in order to have it available for future
checks.
To activate this mode, the boiler must be in “Stand-by” mode.
If the boiler is connected to the CAR
V2
the “stand-by”
function can only be activated via the remote control
panel.

To activate the function, press
the buttons “ ” and “ ”
simultaneously until function
activation, which is displayed
by indicating the fan operation
speed (in hundreds of revs) and
ignition of the flashing “ ”
and “ ” symbols.
The appliance remains in this mode for a maximum period of 15
minutes, keeping the fan speed constant.
This function ends once 15 minutes have elapsed, or by discon-
necting supply voltage to the boiler, or by pressing the “ ”
button.
Check the ΔP between the two pressure test outlets (Fig. 37) and
set parameter F0 according to the values shown in the table below:
Victrix Omnia
Parameter F0 Pressure
0 < 90 Pa
1 90 ÷ 120 Pa
2 120 ÷ 150 Pa
Value detected on first check
Examinations are carried out by sealing the holes pro-
vided to analyse the flues, making them pneumatically
sealed.
Should there be a boiler malfunction, you can carry out a
flue test to check that there are no obstructions in the flue
system. Different values to those indicated in the previ-
ous tables indicate a flue system malfunction, especially
a flue system with excessive load losses or obstructed
system.
