Connecting A Fireplace Or Open Hearth To The Flue; Ventilation And Aeration Of The Installation Premises - Nordica ORIANA User Manual

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.
The chimney pressure (DRAUgHT) must be at least - Pascal (see chap. TECHNICal DaTa sHEET). 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 is necessary to reduce the same by installing an additional draught
regulator (butterfly valve) on the exhaust pipe or in the chimney, according to the regulations 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.

VENTILATION AND AERATION OF THE INsTALLATION PREMIsEs

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 flexible pipe. The connection pipe (not furnished) must be flat with a minimum
Picture 10, 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
diameter of
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 fireplace's door closed.
The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and ventilation),
as long as the flow 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.
