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
2) .
OF THE FLUE (Picture
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.

CONNECTION TO THE CHIMNEY

Products with automatic door closing 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 must be connected to their own flue.
Operation with doors open is only allowed when supervised.
The connection pipe to the flue 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,comply with all current Standards and Regulations and to those envisioned by
the law, and be hermetically secured to the flue. The internal diameter of the connection pipe must correspond to the external diameter of the
appliance flue gas exhaust stub pipe (DIN 1298).
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 PROPERLY SPACED FROM ANY
FLAMMABLE MATERIALS OR FUELS THROUGH A PROPER INSULATION OR AN AIR CAVITY.
MINIMUM DIsTANCE sAfETY 25 CM..
IMPORTANT: THE UNUsED fLUE gAs EXHAUsT HOLE MUsT BE COVERED WITH ITs REsPECTIVE CAP (SEE CHAPTER:
DIMENSIONS)
The chimney pressure (DRAUgHT) must be at least (see chap. TECHNICAL DATA SHEET - Pascal).
THE MEASUREMENT HAS ALWAYS TO BE CARRIED OUT WITH HOT DEVICE (rated thermal performance).
When the depression exceeds 17 Pa (=1.7 mm of column of water), it should be reduced with the installation of an AUTOMATIC ADDITIONAL
DRAFT REGULATOR on the exhaust outlet or in the chimney.
If it is not possible to install an automatic additional draft regulator, then install a BUTTERFLY VALVE in line with current legislation in force.
FOR CORRECT APPLIANCE OPERATION, IT IS ESSENTIAL THAT SUFFICIENT AIR FOR COMBUSTION IS INTRODUCED INTO THE
PLACE OF INSTALLATION (SEE PARAGRAPH VENTILATION AND AERATION OF THE INSTALLATION PREMISES).

CONNECTINg A fIREPLACE OR OPEN HEARTH TO THE fLUE

The flue gas channel is the stretch of piping which connects the product to the flue. In the connection, these simple but extremely important
principles must be respected:
• UNDER NO CIRCUMSTANCES USE A FLUE GAS CHANNEL WITH A DIAMETER LESS THAN THAT OF THE EXHAUST CLAMP WITH WHICH
THE PRODUCT IS EQUIPPED;
• EACH METRE OF THE HORIZONTAL STRETCH OF THE FLUE GAS CHANNEL CAUSES A SLIGHT LOSS OF HEAD WHICH MUST BE
COMPENSATED IF NECESSARY BY ELEVATING THE FLUE;
• THE HORIZONTAL STRETCH MUST NEVER EXCEED 2 METRES (UNI 10683);
• EACH BEND OF THE FLUE GAS CHANNEL SLIGHTLY REDUCES THE FLUE DRAUGHT WHICH MUST BE COMPENSATED IF NECESSARY BY
ELEVATING IT SUITABLY;
• THE UNI 10683 – ITALY REGULATION REQUIRES THAT UNDER NO CIRCUMSTANCES MUST THERE BE MORE THAN 2 BENDS OR
VARIATIONS IN DIRECTION INCLUDING THE INTAKE INTO THE FLUE.
If the user wishes to use the flue as a fireplace or open hearth, it is necessary to seal the hood below the entrance point of the flue gas channel
pos. A Picture 5.
If the flue is then too big (e.g. 30x40cm or 40x50cm), it is necessary to intubate it with a stainless steel tube with a diameter of at least 200mm,
pos. B, taking care to close the remaining spaces between the pipe and the flue immediately under the chimney pot pos. C.
