CONNECTINGAFIREPLACEOROPENHEARTHTOTHEFLUE
The ue gas channel is the stretch of piping which connects the product to the ue. 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 ue as a replace or open hearth, it is necessary to seal the hood below the entrance point of the ue gas channel
pos. A Picture5.
If the ue 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 ue immediately under the chimney pot pos. C.
VENTILATIONANDAERATIONOFTHEINSTALLATIONPREMISES
AS THE PRODUCT DRAW THEIR COMBUSTION AIR FROM THE PLACE OF INSTALLATION, IT IS MANDATORY THAT IN THE PLACE ITSELF, A
SUFFICIENT QUANTITY OF AIR IS INTRODUCED. IF WINDOWS AND DOORS ARE AIRTIGHT (E.G. BUILT ACCORDING TO ENERGY SAVING CRITERIA),
IT IS POSSIBLE THAT THE FRESH AIR INTAKE IS NO LONGER GUARANTEED AND THIS JEOPARDISES THE DRAUGHT OF THE APPLIANCE AND YOUR
HEALTH AND SAFETY.
IMPORTANT:For a better comfort and corresponding oxygenation of environment, the combustion air can be directly withdrawn at the
outside through a junction which is to be connected with a exible pipe. The connection pipe (not furnished) must be at with a minimum
diameter of Picture..1, a maximum length of 3 m and with no more than 3 bends. If there is a direct connection with the outside it must be
endowed with a special windbreak.
THERE MANDATORY BE SUFFICIENT QUANTITY OF AIR FOR COMBUSTION AND RE-OXYGENATION OF THE ROOM TO ENSURE THE DEVICE WILL
WORK PROPERLY. There should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even
when the doors and windows are closed.
The air inlets must meet the following requirements:
• THEY MUST BE PROTECTED WITH GRIDS, METAL MESH, ETC., BUT WITHOUT REDUCING THE NET USEFUL SECTION;
• THEY MUST BE MADE SO AS TO MAKE THE MAINTENANCE OPERATIONS POSSIBLE;
• POSITIONED SO THAT THEY CANNOT BE OBSTRUCTED;
• ANY EXTRACTOR HOODS IN THE ROOM WHERE THE DEVICE IS INSTALLED MUST NOT OPERATE AT THE SAME TIME as this could cause
smoke to enter the room, even with the replace’s door closed.
The clean and non-contaminated air ow can also be obtained from a room adjacent to that of installation (indirect aeration and ventilation),
as long as the ow takes place freely through permanent openings communicating with the outside.
THE ADJACENT ROOM CANNOT BE USED AS A GARAGE, OR TO STORE COMBUSTIBLE MATERIAL OR FOR ANY OTHER ACTIVITY WITH A FIRE
HAzARD, BATHROOM, BEDROOM OR COMMON ROOM OF THE BUILDING.
Ventilation is deemed sucient when the room is equipped with air inlets according to the table:
