MF GAS SYSTEM FAST CASUAL GENIUS FUNCTIONS AND USE
A. MARANA FORNI GAS MF AND FAST CASUAL GENIUS ROTARY OVEN SYSTEM - AUTOMATIC
MODE
Automatic Fast Casual Genius. The fast casual genius system uses the 1 cookplate
revolution cooking/time concept.
Introduction: The fast casual GENIUS system has been equipped with the intelligence
required for fully automatic performance the cooking functions, with no operator
intervention. The functions range from programming of the oven's temperature
during the use, the quantity of flame used during cooking, modulation of the burner
flame in relation to oven temperature, to on-off operation of the turbo burner which
heats the cook plate for perfect cooking of the underside of the pizza.
To be able to work in automatic mode, the fast casual GENIUS system, needs two
GENIUS consoles connected together and must both be switched on, and the gas
console must be set in automatic mode.
Fast casual GENIUS system switch-on procedure
Switch on the oven console and then the gas console.
AT SWITCH-ON, THE FAST CASUAL GENIUS SYSTEM WILL BE IN AUTOMATIC MODE.
