HEATING SYSTEM FILLING AND
After making hydraulic connection, fill the heating system
in.
This operation is to be performed
when the system is cold, as
follows:
- unscrew the automatic air
discharge valve cap (A) by two
or three turns
- open the filling cock, external to
the system until water gauge
pressure reaches approx. 1 bar
(fig.8).
When the plant is full, close the
filling cock.
The boiler is equipped with an
effective air separator, therefore no
manual operation is required.
The burner only starts when the
air discharge phase is completed.
Heating system emptying
Empty the system as follows:
- turn the boiler off
- connect a small rubber pipe to
boiler exhaustion valve (B)
- untighten the valve
- empty the lowest parts of the
system.
ATTENTION
The safety valve exhaustion
is to be connected to a proper
collection system.
The manufacturer is not
responsible for any flooding
possibly provoked by the
activation of the safety valve

system immediately stops
appliance operation.
Proper fume exhaustion control
device must always operate.
Safety devices are only to be
replaced by Technical Service
exclusively using original
components.
After repair, perform an ignition
test and check proper operation
of fume exhaustion thermostat.
Exhaustion duct and flue union
must comply with national and
local Standards and/or
regulations.
Using rigid ducts is compulsory,
junctions between elements
must be tight and
components must be resistant to
temperature, condensates and
mechanical stresses.
Non-insulated exhaustion ducts
can be dangerous.
Combustion air and room
ventilation opening must comply
with technical standards.
Do not obstruct or reduce
dimensions of installation room
ventilation openings.
