4.4.3. Adjustment during the test
Values of the minimum ignition failure: Offset Adjust gas valve (PR.ADJ.)
If the combustion values at minimum power do not
correspond to the recommended offset adjusting of
the valve is needed.
To do this with a screwdriver unscrew the protective
brass cap and take a 4mm Allen wrench.
At this point, if the CO2 is lower than the
recommended value, screw clockwise (see figure at
right), to enrich the mixture.
If the CO2 is higher unscrew slowly to lessen the
mixture.
The adjustment is very sensitive and you should make
small movements (a quarter turn rotation involves a variation of about 1% CO2) and wait
for the gas analyzer to detect the change and stabilize.
Once done repeat the wizard test.
When the adjustment is finished refit the protective cap of the screw.
Attention: the pressure adjustment screw PR.ADJ. has no effect on
increasing the power of the oven.
