NORmaL OPERaTION

After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations. yOu sHOuLD aLways usE THE PRODuCT wITH THE DOOR CLOsED IN ORDER TO avOID DamaGEs DuE TO
OvERHEaTING (FORGE EFFECT). THE INOBsERvaNCE OF THIs RuLE makEs THE waRRaNTy ExPIRE.
with the registers located on the front of the device, it is possible to adjust the heat emission of the same. They have to be opened according to
the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most part of the air for combustion
flows through the secondary air register.
NEvER OvERLOaD THE aPPLIaNCE. TOO MUCH FUEL AND TOO MUCH AIR FOR THE COMBUSTION MAy CAUSE OVERHEATING
AND THEN DAMAGE THE pRODUCT.
THE waRRaNTy DOEs NOT COvER THE DamaGEs DuE TO OvERHEaTING OF THE EquIPmENT.
you should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect).
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of pascal (see chap. TECHNICAL DATA
SHEET) is the following one: see chap. TECHNICAL DESCRIpTION.
THE aPPLIaNCE wORks as aN INTERmITTENT OPERaTING aPPLIaNCE.
BESIDES THE ADjUSTMENT OF THE AIR FOR THE COMBUSTION, THE INTENSITy OF THE COMBUSTION AND CONSEqUENTLy THE THERMAL
pERFORMANCE OF THE DEVICE IS INFLUENCED By THE STACk. A GOOD DRAUGHT OF THE STACk REqUIRES A STRICTER ADjUSTMENT OF
AIR FOR COMBUSTION, wHILE A pOOR DRAUGHT REqUIRES A MORE pRECISE ADjUSTMENT OF AIR FOR COMBUSTION.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).

OPERaTION DuRING TRaNsITION PERIODs

DURING TRANSITION pERIODS wHEN THE ExTERNAL TEMpERATURES ARE HIGHER, IF THERE IS A SUDDEN INCREASE OF TEMpERATURE IT
CAN HAppEN THAT THE COMBUSTION GASES INSIDE THE FLUE CANNOT BE COMpLETELy SUCkED Up.
THE ExHAUST GASES DO NOT COME OUT COMpLETELy (INTENSE SMELL OF GAS).
In this case, shake the grating more frequently and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit
a rapid burning (growing up of the flames) and the stabilization of the draught.
THEN, CHECk THAT ALL OpENINGS FOR THE CLEANING AND THE CONNECTIONS TO THE STACk ARE AIR-TIGHT. IN CasE OF
DOuBT, DO NOT OPERaTE THE PRODuCT.
