regularly emptied, so that the ash does not obstruct the primary air entry for the combustion. Through the primary air the fire is also kept
alive. When the knob is completely on the left, the register is closed, when the knob is completely on the right the register is opened.
During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns too fast and the
cooker may overheat.
2A – SECONDARY AIR CONTROL
On the hearth door there is the secondary air register. This knob must be totally moved to the right in order to open the control, especially
for wood combustion (see paragraph Table). The secondary air, passing between the double glass of the fire door, heats itself starting the
double combustion and keeping at the same time the glass clean (with open register).
B – SMOKES control
(Picture 6 at page
(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 flow around the oven and directly into the flue
and up to the chimney. OVEN COOKING: when the control bar is pulled out, the combustion gases flow around the oven, heating it.
To ignite the flame follow the instructions below (see Cap. IGNITION) :
•
Bring the flue gas control to the cooker position (any butterfly valve placed on the flue gas exhaust pipe must also be opened).
•
Open the primary and secondary air control.
•
After having started the fire with small pieces of wood and waited until it is well lit.
•
Bring the flue gas control to the oven position.
•
Close any butterfly valve placed on the flue gas exhaust pipe must also be opened.
The control regulation during the ignition phase is the following :
Ignition phase
The control regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):
6. FLUE
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;
•
there must be no narrowing and vertical passages with deviations must not be greater than 45°;
•
if already used, it must be clean;
•
the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough
