Attention
• Do not use volatile, flammable substances
(petrol, alcohol etc.) for lighting the fire.
• Do not use fuels which could release toxic
substances or pollutants.
• Do not put the fire out by throwing water on it.
• Check the external and internal air intakes, and
the flue pipe, at least once a year, arranging for
them to be cleaned.
• During use, the metal parts and the glass reach
high temperatures. For all jobs of loading the
stove, adjustment or cleaning the ash drawer,
use the insulating glove provided.
• Never leave children unattended near the
fireplace stove when it is in use.
• The risk of burns from contact with hot surfaces
is very high.
6.5. LOADING THE FUEL
For normal fuel loading, open the fire door by lifting one of the handles
as shown in figure 12. To close the door, do the opposite.
During use, the metallic structure, the handles and the glass
become very hot. Use the thermal glove provided when
handling these parts.
During normal use, always keep the fire door completely down
and closed. Intermediate positions cause abnormal combustion (forge
effect), rapid wood consumption, and may cause smoke to leak out due
to the high temperature of the fire box.
Open the door only to add fuel, and only for brief periods of
time.
The fireplace stove works best and provides the greatest yield when the
door is closed, because the hermetic combustion chamber and the
calibrated inlet of oxygen allow increased performance.
Nominal combustion has a duration of 50 min. Therefore, to
obtain the nominal hourly loading set forth in the table in
chapter 3, load the amount shown in parentheses in the
table every 50 minutes.
6.6. CONTROL OF COMBUSTION
PRIMARY AIR
The fireplace stove is equipped with two flanged side holes Ø100 mm
for the inlet of primary air which ensures combustion and helps keep
the glass clean.
. Moving the lever to the left provides the full aperture, and more rapid
combustion, while moving it to the right closes the opening, with slower
burning.
