The control regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):
ITALY TERMO BUILT-IN DSA
FLUE GAS Control ( Picture 7 at page 60
(Conversion from the cooker HOTPLATE USE – OVEN USE function to the cooker HEATING function)
In the central part of the instrument panel, there is the flue gas control, which can be recognised from its enamelled, labelled knob.
When the control is positioned to the LEFT (on the pan symbol), the combustion gases flow above and around the oven (oven function
– HOTPLATE USE – OVEN USE); when positioned to the RIGHT (on the water symbol), the gases flow near the boiler, increasing the
temperature evenly, favouring water heating inside it (cooker function HEATING USE).
IGNITION Control ( Picture 7 at page 60
On the front of the cooker, between the protective handrail and the flue gas control, there is the ignition control control lever, which can be
recognised by a chrome-plated knob.
This control must only be used to facilitate the ignition of fuel in the cooker. Pull the lever outwards from the cooker (control open).
IMPORTANT : during normal cooker operation, the control lever must remain completely inserted (pushed inwards on the cooker). In this
way avoiding excessive fuel consumption and poor thermocooker output (control closed).
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Open the ignition control to aid flue gas exhaust. Position the control (any butterfly valve placed on the flue gas exhaust pipe must also
be opened).
• Position the thermostat knob on position 5 (maximum opening).
• Open the primary air control (placed on the ash tray).
• After having started the fire with small pieces of wood and waited until it is well lit, adjust the thermostat to the positions corresponding
to the desired heat (0÷5).
• Bring the flue gas control to the oven position.
• Close the ignition control (and any butterfly valve placed on the flue gas exhaust pipe must also be opened).
The control regulation during the ignition phase is the following :

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
and porous internal surfaces.
The minimum section must be 4 dm
dm (for example 25x25 cm) for appliances with a diameter of more than 200 mm.

The draught created by your flue must be sufficient but not excessive.
A section of the flue which is too large can present a volume which is too large to heat and therefore cause operating difficulties 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 flue must be at a suitably distance from flammable or combustible material using suitable insulation or an air space.
It is FORBIDDEN to pass system piping or air ducts inside the flue. It is also forbidden to create moveable or fixed openings on the flue
itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).
6.1.

CHIMNEY POT

The flue 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 flue
(Picture 3 at page 57) .
As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind
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 flue.
• Be built so as to prevent rain, snow or any foreign body entering the flue.
• Be easy to inspect, for any maintenance and cleaning operations.
