(fig. 27):
Tighten the screw of primary air (P).
Fully tighten the adjustment screws of the secondary air (S)
to “feel” the resistance of the spring that pushes the closing
plates
At this point, “unscrew” the screw of 10 turns of primary air
(P) and of 4 turns the screws of the secondary air (S).
Or the models AIREX 65 2S, AIREX 80 2S (fig. 28):
The starting position the rings (pos. 1, fig. 28) that command
the opening or closing of the primary and secondary air
should be about halfway on the threaded rod.
Through the upper manifold the primary air is blown (P)
while the lower one put in the secondary air (S)
At this point, “screw” or “unscrew” the rings (pos. 1, fig. 28)
on the threaded rod until obtaining an optimal air adjustment
observing the color of the flame in the lower combustion
chamber.
Please note that screwing the ring in the clockwise sense
will result an increase of the air intake ( primary and
secondary) Conversely, a decrease.
Open the top loading and place on the main stone, a little
‘fine and dry wood, placed crosswise.
Use highly flammable material, and avoid large pieces and
with form of squares
Light the wood using thin sheets of paper (newspaper or
similar)
Approach the top door and turn on the fan. Wait a few
minutes that the fire takes and produce the
coals (5 - 10 minutes).
After few minutes If looking through the light of lower door it
will see that the flame inversions is beginning, add more

c) 100 cm (+ 1 cm - 4 cm) for the model AIREX 80 2S
These measures must be strictly observed.
As for a good combustion is essential that there is a uniform
descent of the wood is necessary to ensure that the length
of the pieces introduced, the form and manner of loading
does not prevent the descent of the regular fuel.
The pieces must be placed longitudinally and horizontally.
No piece has to be tilted or placed sideways
