high temperatures. For all loading, adjustment or
ash cleaning operations, use the insulated glove
provided.
• Never leave children unattended near the insert
when it is in use.
• The risk of burns from contact with hot surfaces
is very high.
• In the event of poor weather conditions for
insert use (low pressure, moderate
temperatures, wind) back draught may occur in
the chimney flue. If this occurs, use a small
quantity of paper to heat the chimney flue and
restore normal draught. Afterwards, proceed
with normal product lighting.
5.4. FORCED VENTILATION OPERATION for the
SMARTBOX MODELS
The insert is equipped with two internal fans for forced propagation of
the air inside the cavities of the product. The fans are internally
mounted on the lower part of the insert structure.
The flow of hot air created by these fans is very slight in order
to keep the temperature of the air coming out of the outlet
very high and promote convection heating.
Using the control button located on the lower front panel
(figure 10), it
is possible to select the desired operation mode:
• Button on I = MANUAL operation
• Button on II = AUTOMATIC operation.
IT IS NOT POSSIBLE TO SWITCH THE VENTILATION
OFF IF THE INSERT IS ON; this is to prevent high
temperatures from damaging the structure.
5.4.1. Manual operation
When the switch is positioned on I, the fans are always on, regardless
of whether or not there is a fire inside the mouth of the insert.
To switch the ventilation off, when the fire is out, the switch must be
positioned on II; in fact, in this case the internal probe, if it is not at
temperature (~50°C), will not allow operation of the fans.
5.4.2. Automatic operation
When the switch is positioned on II the fans switch on/off exclusively
when the temperature of the probe is higher/lower than
50/60°C.
