Then, to test the correct functioning of the burners,
exit the screen by pressing 1.
To test chamber burner [br1], turn scroller 5 until
[br1] on display 2, and then start-up the cycle with
the 6 "START/STOP" button.
The burner will go in pre-ventilation to then pass on
to the set IGN ignition. The first IGN ignition stage
is indicated on display 4, by the first point under the
speed value.
Then, the minimum and maximum speed stages,
indicated respectively in the second and third points,
will automatically activate.
The correct burner functioning is highlighted by
the increase of the temperature in the cooking
compartment.
To deactivate burner functioning, press button 6
"START/STOP" again.
To exit the cycle press button 1.
NOTE: To check/adjust the boiler burner, activate the
Boiler Burner section (example [br2]) as operated for
cooking compartment burner heating.
During testing, it is possible to manually block the
sequence by pressing button 1; this way, the burner
blocks in the desired phase (ex. IGN ignition) allowing
the technician to carry out other verifications in this
phase.
When a phase is blocked, the point indicating phase
1, 2 or 3 flashes.
To restart the sequence, always press button 1.
NOTE: in case of maximum speed, the cycle block
becomes pointless since the oven is already working
normally; it is possible to shift to minimum phase by
pressing key 1.
To carry out the tests with the door open, once
the cycle is started, press the "CLIMA" button;
this function is useful during combustion analysis
and for functioning tests of the prolonged burner
without reaching the temperature previously set in
the chamber.
