1. 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 domestic hot water supply system in compliance with its
performances and output power.
Have the boiler installed by a Qualified Service Engineer and ensure the
following operations are accomplished:
a) Accurate purging of the whole pipework in order to remove any
deposits.
b) Careful checking that the boiler is fit for operation with the type of
gas available. For more details see the notice on the packaging
and the label on the appliance itself.
c ) Careful checking that the flue terminal draft is appropriate; that the
terminal is not obstructed and that no other appliance exhaust
gases are expelled through the same flue duct, unless the flue is
especially designed to collect the exhaust gas coming from more
than one appliance, in conformity with the laws and regulations in
force.
d) Careful checking that, in case the flue has been connected to pre-
existing flue ducts, thorough cleaning has been carried out in that
residual combustion products may come off during operation of
the boiler and obstruct the flue duct.
2. Instructions prior to commissioning
Initial lighting of the boiler must be carried out by a licensed technician.
Ensure the following operations are carried out:
a) compliance of boiler parameters with (electricity, water, gas) supply
systems settings.
b) compliance of installation with the laws and regulations in force.
c ) appropriate connection to the power supply and grounding of the
appliance.

3. Commissioning of the boiler
To correctly light the burner proceed as follows:
1) provide power supply to the boiler;
2) open the gas cock;
3) turn the selector switch (1) to set the boiler on summertime (
or wintertime (
4) turn the central heating (12) and domestic hot water (13) adjusting
controls in order to light the main burner.
To increase temperature values turn the control clockwise and
anticlockwise to decrease it.
When on summertime operation (
pump will start running only when there is a call for hot water.
Warning:
During initial lighting, until the air contained in the gas pipes is not released,
the burner may fail to light immediately and that may cause a 'blockage' of
the boiler.
Under such circumstances we recommend you repeat the ignition
procedure until gas is delivered to the burner, and briefly set knob (1) to
