The heating of the room takes place:
a)
by means of radiation: through the panoramic glass and the hot external surfaces of the stove, heat is radiated into the room.
b)
by conduction: through radiators or convectors in the central heating system fed by the hot water produced by the Thermocooker
itself.
The thermocooker is supplied with registers for primary and secondary air and a thermostat with which the combustion air is regulated.
PRIMARY Air Register (lower knob on the furnace door
With the lower register, the passage of primary air in the lower part of the cooker is regulated through the ash drawer and the grill in the
direction of the fuel. The primary air is necessary for the combustion process. The ash drawer must be emptied regularly, so that the ash
cannot block the primary air intake for combustion. The primary air also keeps the flame alive.
The primary air register must be almost completely closed during wood combustion, as otherwise the wood burns too quickly and the
thermo-product may overheat.
sECONDARY Air Register (upper knob on the furnace door
This knob must be open (i.e. turned completely to the right), in particular for the combustion of wood (see Table). The secondary air, passing
between the double glass of the fire door, heats up and triggers the dual combustion, keeping the glass clean at the same time (register
open).
AUTOMATIC Thermostat
(Picture 7
The thermostat has the task of automatically increasing or decreasing combustion.
Dependent on the position chosen, the thermostat will act on the valve which regulates the intake of air into the furnace, placed on the
back of the cooker. Turn it in a clockwise direction to make up the fire and in an anti-clockwise direction to reduce combustion. As this is an
extremely precise device, it is advisable to turn it carefully and never force the knob.
FLUE gAs Register
(Picture 7
(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 flow above the oven directly
towards the exhaust stub (cooker function – PLATE USE); when the lever is pulled towards you, the combustion gases flow all around the
oven, so the internal temperature increases evenly (cooker – oven cooking and heating – OVEN USE).
The register regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):
Fuel
WOOD
To ignite the flame follow the instructions below (see Cap. IGNITION) :
•
Bring the flue gas register to the HOTPLATE USE position to aid flue gas exhaust. Position the register (any butterfly valve placed on the
flue gas exhaust pipe must also be opened).
•
Position the thermostat knob on position maximum opening.
•
Open the primary air register (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 .
•
Bring the flue gas register to the OVEN USE position.
•
Close the any butterfly valve placed on the flue gas exhaust pipe must also be opened.
THE 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.
Picture 1
The minimum section must be 4 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.
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements
provided by UNI 10683 standard. 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).
