(Conversion from the cookerHOTPLATEUSE – OVENUSE function to the cooker HEATINGfunction)

On the right of the front of the stove/cooker, between the protection rail and the oven door, is the smoke-register control lever, recognisable

as a bronze knob. When the lever is pushed towards the back of the stove/cooker, the combustion gases ow above the oven directly

towards the exhaust stub (cooker function – PLATE USE); when the lever is pulled towards you, the combustion gases ow all around

the oven, so the internal temperature increases evenly (cooker – oven cooking and heating – OVEN USE).

To ignite the ame follow the instructions below (see Cap. IGNITION) :

• Bring the ue gas register to the oven position.

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

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

Hourly consumption in kg / h PRIMARY air Register SECONDARY air Register TERTIARY air

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

products and any condensation;

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

and porous internal surfaces. Picture 2 at page 81 shows some example solutions.

The minimum section must be 4 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.

The ue draught depends on the suitability of the chimney pot.

It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the ue

(Picture 3 at page 81) .

As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 4 at page 82).

The chimney pot must meet the following requirements:

• Have an internal section equivalent to that of the chimney.

• Have a useful exit section of double the internal section of the ue.

• Be built so as to prevent rain, snow or any foreign body entering the ue.

• Be easy to inspect, for any maintenance and cleaning operations.
