that the ash does not obstruct the entry of the primary air for the combustion.

In order to open the air ow, the bar must be completely pulled out.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.

2A- SECONDARY air register (Picture 7 at page 55).

Below the hearth door, on the right front side there is the secondary air register.

The secondary air, passing through the two lateral jambs of the front side, heats itself starting the double combustion and keeping at

the same time the glass clean ( with open register).

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 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).

5.1. 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

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

5.2. CONNECTION TO THE CHIMNEY

Products with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (except during the fuel loading

or ash removal phases).

Products with non-automatic door closing (type 2) must be connected to their own ue.

Operation with doors open is only allowed when supervised.

The connection pipe to the ue must be as short as possible, straight horizontal and positioned slightly in ascent, and watertight.

Connection must be carried out with stable and robust pipes (we recommend a thickness of 2 mm) and be hermetically secured to the ue.

The internal diameter of the connection pipe must correspond to the external diameter of the cooker ue gas exhaust stub pipe (DIN 1298).

ATTENTION: as far as concern the realisation of the ue connection and ammable materials please follow the requirements provided by
