SECONDARY AIR:
The introduction of secondary air is predetermined, and is used for the
partial cleaning of the glass and allows the completion of the
combustion process. Consequently, if it is well calibrated, the efficiency
and heating performance of the stove are higher.
5.3.2.1.
VELD stove air control
Move the control lever towards the right if you want more combustion
air to enter the combustion chamber. Vice versa move the lever
towards the left if your want less air inlet.
The primary and secondary air inlet is predetermined; move the lever
to dose the quantity of primary and secondary inlet air.

PRIMARY AIR LEVER (TURNED TOWARDS THE RIGHT)
The lever turned towards the right (pos.1) is designed to bring a large
quantity of primary air beneath the combustion chamber fire plane, to
allow rapid and effective ignition of the fire (Fig.4).
SECONDARY AIR LEVER (TURNED DOWN)
Secondary air, as mentioned above, allows the completion of
combustion and increases the efficiency (lever in pos.2 - fig.5).
The position of the lever in fig.5 determines the nominal output,
minimizing primary air and the secondary air inlet.
LEVER TURNED TOWARDS THE LEFT
From this point, turn the lever clockwise to decrease the quantity of air
in the combustion chamber until position 3 is reached, where only a
minimum quantity of primary air is present (fig.6).
This position is used to prolong combustion (for instance, at night, or
when you are not at home) so that the stove is set to minimum for
auto-combustion, to save on fuel and keep the flame burning.
