Flue; Chimney Pot - LA NORDICA CANDY Instructions Pour L'installation, L'utilisation Et L'entretien

CANDY - BRIGITTA
The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderful view on the burning
flames. Furthermore, it is thus avoided the output of sparks and smoke.
Below the hearth door will be found an extractable ash-drawer with a closing door
The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the stove, the heat
is radiated into the environment See chapter CALCULATION OF THE THERMAL POWER).
ACCESSORIES
The stove is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A - PRIMARY air register
With the air register located under the door of the hearth, it is possible to adjust the air flow through the ash drawer and the grating in
direction of the fuel. The primary air is necessary for the combustion process during the ignition. In order to open the passage of primary
air the lever should be completely pulled. The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of primary air
for the combustion. Primary air is also necessary to keep fire live. When the control is completely on the left, the register is closed, when
the knob is completely on the right the register is opened. During the combustion of wood, the primary air register must be opened only
a few, since otherwise the wood burns quickly and the device can overheat (see chapter NORMAL OPERATION).
2A - SECONDARY air register
Over the hearth door there is the secondary air register. Also this control must be opened (then moved to the right), especially for wood
combustion, so that unburnt carbon does not undergo a post-combustion (see chapter NORMAL OPERATION).
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

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.
2
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).
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
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.
