5-OPERATION
FUEL LOADING
For normal fuel loading simply open the hearth door acting with the supplied cold handle on one of the outlets to the right or left of the
closed fireplace, as shown in figure 11-12-13. Simply insert the cold handle into the hole and lift the door upwards. To close the door
perform the same procedure in reverse order.
During use the metal structure and glass reach high temperatures, so use suitable thermal protection (for example
gloves). During normal use always keep the hearth door completely lowered/closed, as intermediate positions cause anomalous
combustion (forge effect); a rapid consumption of wood may also cause release of smoke due to the high temperatures of the fireplace.
Open the door solely for fuel loading operations and only for brief periods.
The closed fireplace has maximum efficiency and works best with the door closed, as the combustion chamber tightness and the calibrated
oxygen input enable to raise performance levels.
Nominal combustion lasts 50 minutes. Therefore to achieve the nominal hourly loading envisaged in the table in
chapter 3, load the amount expressed in brackets in the same table every 50 minutes.
