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 ues 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 at page 40 shows some example solutions.

The minimum section must be 4 dm

2

(for example 20x20 cm) for appliances whose pipe dimensions are less than 200 mm, or 6.25

dm
2

(for example 25x25 cm) for appliances with a diameter of more than 200 mm.

The draught created by your ue must be sufcient but not excessive.

A section of the ue which is too large can present a volume which is too large to heat and therefore cause operating difculties 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 ue must be at a suitably distance from ammable or combustible material using suitable insulation or an air space.

It is FORBIDDEN to pass system piping or air ducts inside the ue. It is also forbidden to create moveable or xed openings on the ue
itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).

6.1. CHIMNEY POT

The ue 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 ue

(Picture 2 at page 40) .

As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3 at page 41).

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 ue.

• Be built so as to prevent rain, snow or any foreign body entering the ue.

• Be easy to inspect, for any maintenance and cleaning operations.

1A - PRIMARY air register (Picture 6 at page 43)
With the air register located under the door of the hearth (on the left), it is possible to adjust the air ow 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 re live.

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 (Picture 6 at page 43)

Under the door of the hearth (on the right) there is a secondary air register.

This valve must be opened (and therefore completely pushed), in detail, for the combustion of wood, so that unburnt carbon can be
subject to a post-combustion, increasing the yield and assuring the cleaning of the glass (see chapter NORMAL OPERATION).
It is possible to get the air SECONDARY directly from outside through a exible tube (reproof NOT furnished Picture 8 at page 43 Ref

A).

The adjustment of the registers necessary to reach the rated caloric yield is the following one:
