The Flue; Chimney Pot - La Nordica TERMOCUCINOTTA EVO Manual Del Usuario

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.
1A - PRIMARY Air Register / AUTOMATIC Thermostat
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 from 0 to 5 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.
2A - sECONDARY Air Register
This register must be open (i.e. turned completely to the right), in particular for the combustion of wood (see paragraph NORMAL
OPERATION). 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).
The register regulation necessary in order to obtain nominal calorific output is the following (see Cap. NORMAL OPERATION):
TERMOCUCINOTTA - DsA
TERMOCUCINOTTA EVO - DSA
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Open the butterfly valve placed on the flue gas exhaust pipe must also be opened.
• Position the thermostat knob on position 5 (maximum opening).
• 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).
• Close the butterfly valve placed on the flue gas exhaust pipe must also be opened.
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;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• 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
For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
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).

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
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.
