The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the stove, the heat

is radiated into the environment.

The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.

1A – PRIMARY AIR CONTROL (Picture 6 at page 62)

With this air register, it is adjusted the passage of primary air into the low part of the cooker, through the drawer of ash and the grate

in the fuel direction. The primary air is necessary for the combustion process. The ash drawer must be regularly emptied, so that the ash

does not obstruct the primary air entry for the combustion. Through the primary air the re is also kept alive. When the knob is completely

heats up and triggers the dual combustion, keeping the glass clean at the same time (register open).

B – FLUE GAS Control (Picture 6 at page 62)

(Conversion of the cooker function to the cooker, bake oven and heating function).

The smokes control, in the style of a chromed pull push lever, can be found on the top right corner of the front side of the cooker, between

the protection bar and the oven door. This control has two settings: HOB COOKING when the bar is pushed to the back of the cooker, the

combustion gases ow around the oven and directly into the ue and up to the chimney. OVEN COOKING when the control bar is pulled

out, the combustion gases ow around the oven, heating it.

The control regulation necessary in order to obtain nominal caloric output is the following (see Cap. TECHNICAL DATA):

PRIMARY air SECONDARY air TERTIARY air

Sovrana EVO CLOSED OPEN PRE-ADJUSTED

• Close any buttery valve placed on the ue gas exhaust pipe must also be opened.

The control regulation during the ignition phase is the following :

Essential requirements for correct appliance operation:

• the internal section must preferably be circular;

• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat, combustion

The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough

and porous internal surfaces. Picture 1 at page 59 shows some example solutions.

The minimum section must be 4 dm

dm

The draught created by your ue must be sufcient but not excessive.

A section of the ue which is too large can present a volume which is too large to heat and therefore cause operating difculties for the

appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a reduction in

draught.
