CONTROL COMBUSTION
7.4.1
PRIMARY COMBUSTION:
creates the main
À
ame which develops in contact with
the log; it is promoted by introducing air into the grate
through the rear combustion air pipe.
The primary air adjustment takes place via the lever on
the front of the machine (
¿
g.-6.2-); moving it to the right
(-) decreases the primary air intake. It is instead increased
by moving it to the left (+).
With the fire burning, the lever can be positioned
approximately half open according to the draw of the
À
ue
pipe and the amount of air to be supplied.
For the
¿
rst ignition of the day, or when using damp wood,
it is advisable to fully open the primary air element to
facilitate ignition.
During operation, the temperature of the registers may
be high, use the glove, as supplied, for their handling in
order to avoid burns.
7.4.2
SECONDARY COMBUSTION:
This is obtained by letting preheated air through the holes
at the top of the back panel. As it enters the wood insert
the air lights the unburned gasses (carbon monoxide)
formed during primary combustion and transforms them
into carbon monoxide (CO2). The effect is easy to see by
the formation of a bed of
À
ames around the holes where
the secondary air is let in.
