6.6 - STARTING
IGNITION
Make sure that the controls referred to in point 6.5
have been performed.
Close the bottom door and power the control board.
The first ignition of the new boiler could be difficult
due to moist refractory cement casting.
Open the top loading door and place small pieces of dry wood
crosswise on the main stone, above the central slot.
Use highly flammable material, and avoid large and square logs.
Light the wood using thin sheets of paper (newspaper or the
likes).
Approach the top door and turn on the fan.
Wait a few minutes for the fire to catch and produce embers
(5 - 10 minutes approximately).
After a few minutes, if looking through the flame sight glass of
lower door you see that the flame inversion is beginning, add
other larger logs.
Close the top door.
Important: during the normal operation of the boiler,
the bypass must always be perfectly closed.
SMOKE PIPES CLEANING SYSTEM CONTROL LEVER
Whenever firewood is loaded, the side lever must be pressed
for a few seconds activating the heat exchanger smoke pipe
cleaning system alternatively.
This will allow the boiler to maintain greater combustion
efficiency.
In this specific case, activating it more frequently will favour
cleaning of the heat exchanger unit.
Use only wood with a moisture content between 13
and 20% in Smoke Control Areas
The firewood must have the following sizes:
a) 100 cm (+ 1 cm, - 4 cm) for AIREX 150
b) 120 cm (+ 1 cm, - 4 cm) for AIREX 200 & 200 UK
The firewood must be of 20 cm diameter maximum.
These measures must be strictly observed.
As for good combustion it is essential that there is a uniform
descent of the wood, it is necessary to ensure that the length of
the wood logs introduced, their shape and the manner of loading
does not prevent the regular descent of the fuel.
The wood logs must be placed longitudinally and horizontally.
No log should be tilted or placed sideways.
When you notice that the flame is reversing, you can proceed
with further loading.
SUBSEQUENT LOADING
Before loading wood once again, consume the previous one as
much as possible.
It can be reloaded when the bed of embers, in the firewood
compartment, will be reduced to a thickness of about 5 cm.
Open the loading door and the internal anti-smoke door slowly.

USEFUL SUGGESTIONS
and LOADING ERRORS TO BE AVOIDED
- Logs which are too long do not fall down properly and can
cause “bridges”.
- Logs which are too short cause irregular air passages, with
consequent reduction in output and efficiency.
- If the quality of the wood causes “bridges”, it could become
necessary to load logs cut in half so that the total length “L”
is as indicated in the previous paragraph.
- Always open the upper door slowly, in order to avoid
blowbacks and smoke formation.
- During normal boiler operation, it is absolutely forbidden to
open the lower combustion chamber door.

It is necessary to use wood logs with the length stated in the
previous paragraph.
Place the new wood logs as described above.
