10. NORMAL OPERATION

After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses and

deformations (according to the instructions on paragraph TECHNICAL DESCRIPTION). 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.

For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing

the ashes, while during the operation and the rest, the door of the hearth must remain closed.

The appliances with constructive system 2 must be connected to their own ue. The operating with open door is allowed under supervision.

cause overheating and then damage the stove. You should always use the appliance with the door closed in order to avoid damages due

to overheating (forge effect). The inobservance of this rule makes the warranty expire.

The adjustment of the registers necessary to reach the rated caloric yield with a depression at the stack of 11 Pa 12 Pa (1,1 mm 1,2mm

of column of water) is the following one: see chapter 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 inuenced 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

10.2. OPERATION IN 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 ue 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 ames) and the stabilization

of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tigh.

In case of doubt, do not operate the product.

11. SUMMER STOP

After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth
