Before performing the test, ensure that the condensate drain trap has been filled correctly and check that there are no obstruc-
tions in the air intake circuit and flue exhaust and that the sealed chamber is perfectly closed and the flue has already been in-
stalled.
The Flue Test activation command is available in the Menu (with Service reserved access) at the following address:
Menu/Service/Special function/Test flue
To activate the flue test, enter the "Test flue" page and on the first line, activate the Test by selecting “Start”.
To end the flue test, select the “Stop” item on the first line.
To define the value to set in the "Flue Length min" parameter, detect the parameters during the "Test flue".
The appliance remains in this mode for a maximum period of 15 minutes, keeping the fan speed constant.
The function ends after 15 minutes, or by selecting “Stop”.
Check the ΔP between the two pressure test outlets (Ref. 14, Fig. 43) and set the parameter “Flue length” according to the values shown in
the tables below:
Victrix Zeus Superior 25
Menu/Assistance/Boiler/Flue Pressure
Min < 75 Pa
Med 75 ÷ 120 Pa
Max 120 ÷ 210 Pa
Value detected on first check
Victrix Zeus Superior 30 - 35
Menu/Assistance/Boiler/Flue Pressure
Min < 122 Pa
Med 122 ÷ 183 Pa
Max 184 ÷ 300 Pa
Value detected on first check
Examinations are carried out by sealing the holes provided 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. Dif-
ferent values to those indicated in the previous tables indicate a flue system malfunction, especially a flue system with excessive
load losses or obstructed system.
