3.7 Air intake
For proper functioning, the appliance should
be positioned in a location where it is able
to take in the air necessary for combustion.
Provide an air intake hole Ø100 mm² close
to the boiler/thermostove. Protect it with a
grill grate from inside and outside,
fig. 8.
The air intake must:
• Be in the installation room;
• Be drown outside with a special con-
nection (wood)
• The exit outside must be protected
with a metal grate;
• Be un-obstructed at all times as these
allow air for comubustion.

- Air Intake
If the air inlet is direct from outside
in the room of installation, its run
should not have changes of direction
and small mesh grill, as can be easily
clogged.
Refer to the national installation re-
gulations for pellet boiler/thermo-
stove.
3.8 Plumbing Connections
Ensure that there is an adequate provision
in the system for heat dissipation from the
boiler, especially in closed-circuit zone he-
ating systems. The charge pressure, with
the system cold, must be between 0.8 and
1.2 Bar.
The following are indicative, non bin-
ding schemes.
