3.12 FLUE TEST
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.
This test makes it possible to assess and if necessary adjust the fan speed according to the length of the installed flue.
To carry out the Flue Test, activate the flue test function FU in the special functions menu (Parag.3.14 and 3.18).
To define the value to be set in parameter "F.0" carry out the ΔP measurement during the "Flue Test".
Check the ΔP between the two flue gas sampling plugs (Parag. 1.34) and set parameter "F.0" according to the values shown below:
Value detected on first check
Value detected on first check
Value detected on first check
The function ends after 15 minutes, or by pressing Reset.
This procedure must not be carried out in the case of installation C
rameter F.1 = 1 set.
Examinations are carried out by sealing the holes provided to analyse the flues, making them pneumatically sealed.
Should there be a appliance 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 previous tables indicate a flue system malfunction, especially a flue system with exces-
sive load losses or obstructed system.
