2. Instructions prior to
installation
This boiler is designed to heat water at a lower than boiling temperature
at atmospheric pressure.
The boiler must be connected to a central heating system and to a DHW
distribution system, in compliance whit its performances and heat
output.
Have the boiler installed by a Qualifi ed Service Engineer and ensure the
following operations are accomplished:
• Accurate purging of the whole pipe work in order to remove any
deposits.
• Careful checking that the boiler is fi t for operation with the type of
gas available. For more details see the notice on the package and the
label on the appliance itself.
• Careful checking that the fl ue terminal draft is appropriate, that the
terminal is not obstructed and that no other appliance exhaust gases
are expelled through the same fl ue duct, unless the fl ue is especially
designed to collect the exhaust gas coming from more than one ap-
pliance, in conformity whit the laws and regulations in force.
3. Instructions prior to
commissioning
First commissioning of the boiler must be carried out by an authorized
Service Engineer. Ensure the following operations are carried out:
• Compliance of boiler parameters with (electricity, water, gas) supply
systems settings.
• Compliance of installation with the laws and regulations in force.
• Appropriate connection to the power supply and grounding of the
appliance.
Electrical safety of the appliance is only guaranteed by correct groun-
ding, in compliance whit the applicable laws and regulations.
The boiler must be electrically connected to a 230 V single-phase +
earth mains with the three-wire cable supplied, observing the polarity
LIVE (L) - NEUTRAL (N).
Use a double-pole switch with a contact separation of at least 3mm
In both poles.
In case you replace the power supply cable fi t a HAR H05 VV-F 3x1
mm
2
cable with an 8 mm diameter max.
The following instructions give important information for the commission
and the use of the device.
The remarks and technical instructions, addressed to Service Engineers
to help them to carry out a faultless installation, will be contained in the
second part of this manual.
