SECONDARY COMBUSTION
It is obtained by injecting preheated air into the fire
box through the holes on the upper part of the back
wall. Entering the fire box the air ignites unburnt gas
(carbon monoxide) formed by the primary combustion,
transforming it into carbon dioxide (CO2). The effect is
clearly visible with the formation of a belt of flames at the
secondary air inlet holes.
6.5.3
Cleaning the glass
During operation of the fireplace it is possible to facilitate
cleaning of the ceramic glass through the pawl without
having to open the door (Fig. 6.5.3a - Fig. 6.5.3b).
This must normally be positioned towards closed flow.
If the pawl is moved, a flow of air opens up, striking the
surface of the ceramic glass, facilitating its cleaning. To
carry out this operation, use the one-finger glove provided.
To perform complete cleaning of the glass it is necessary
to wait for the fireplace to go out and cool and to carry
out cleaning with the appliance cold.
It is performed with a damp cloth or with newspaper paper,
moistened and rubbed in the ash, rubbing the glass until
complete cleaning is obtained (Fig. 6.5.3c).
Sometimes this procedure may not be enough: at this
point it is possible to use specific detergents, taking care
to spray the product onto a dry cloth and not directly
onto the glass of the fireplace or onto the surrounding
painted parts.
Under normal conditions the glass tends to blacken during
ignition and to lighten during operation.
The ceramic glass resists very well at high temperatures,
but it is fragile, so AVOID IMPACTS TO IT.
