FILLING THE HEATING AND DOMESTIC HOT
WATER CIRCUITS
1. Fill the domestic hot water circuit and bring it up to pressure.
IMPORTANT
The hot water tank must be pressurised before the
heating circuit is filled.
2. Fill the central heating circuit making sure that any air in the
upper part of the boiler and any air in the system is bled.
3. Remove the front of the boiler.
4. Check the electrical connections paying particular attention to
the quality of the connections on the power circuit terminals.
5. Set all the switches on the control panel to the Off position and
set the internal magneto-thermal circuit breaker to ON. Replace
the front of the boiler.
6. Switch the boiler on from the external box.
7. Set the ON/OFF switch to the ON position and the summer/
winter selector switch to the winter position.
8 After allowing the circulator to work for a few minutes, set the
ON/OFF switch to the Off position, bleed the circulation pump
and make sure that both the boiler and the system are properly
bled. Adjust the pressure to the static pressure (1 bar = 10 m – 1.5
bar = 15 m) + 0.5 bar.
9. The boiler is now ready to operate. Set the ON/OFF switch to the
ON position, the summer/winter selector, the half and full power
switches and the control thermostat all to the desired positions.
After a few days in operation we advise you to check the
quality of the electrical connections and also make sure
there is no air in either the boiler or the system.
Switch the power supply off from the outside box before
carrying out any work.

ELECTRICAL SAfETY DEVICES
• The boiler must be effectively earthed.
• A box fitted with a magneto-thermal circuit breaker must be
fitted on the outside of the boiler. This is to protect the boiler
and allow the power supply to be switched off during servicing or
other work on the boiler.
first make sure that the system complies with all current
standards.
• To avoid any risk of electrocution, the electrical circuit must be
fitted with a differential circuit breaker.
• The control circuit is protected by a 3A magneto-thermal circuit
breaker.
• The boiler is protected against overheating even if one or more
power switches malfunction by means of a magnetic power
switch placed in series with the power switches.
COMPLIANCE
The installation must be carried out in accordance with the current
local technical standards and legislation.
