6.4.1
Filling the heating side
• Loosen the cap on the factory-fitted automatic air
vent by one or two turns. Make sure that the opening
of the cap does not point towards the electronic com-
ponents.
• Fill the installation up to a system pressure of 2.3 to
2.5 bar. The current water pressure will be displayed if
the "
-
" button is pressed for approx. 3 seconds.
• Fill the system.
• Close the bleed nipple.
• Bleed the radiators.
• Read the pressure again on the pressure gauge. If the
installation pressure has fallen, the installation should
be filled up again and vented once again.
• Check all connections and the entire system for leaks.
You can use the
P0
test program to bleed the heating
circuit, the boiler and, if necessary, the cylinder.
• To do this, keep the "
+
" button pressed for approx.
5 seconds while switching on the mains.
• Select
P0
with the "
+
" or "
-
" buttons.
• Start the program with the "
i
" button.
• Step forward to the cylinder charging circuit by press-
ing again.
6.4.2 Filling
the
siphon
• Fill the siphon with water through the opening in the
flue gas collector.

Danger!
Risk of poisoning from leaking flue gas!
If the unit is operated with an empty conden-
sate siphon, there is a risk of poisoning from
the escaping flue gases. Be absolutely certain,
therefore, to fill the siphon before starting up.
6.5
Checking the gas setting
a
Caution!
Before starting up the boiler compare the de-
tails of the type of gas specified on the identifi-
cation plate with the type of gas supplied at
the installation site. This boiler is suitable for
Natural Gas ONLY.
The combustion of this boiler has been checked, adjust-
ed and preset at the factory for operation on the type
of gas defined on the identification plate. No measure-
ment of the combustion is necessary to set up the
boiler.
• Do not adjust the multifunctional automatic gas valve.
• Ensure
- that the boiler has been installed in accordance with
these instructions,
- the integrity of the flue system and the flue seals,
as described in the flue installation instructions en-
closed with this boiler, and as described below
- a visual check is carried out on the boiler combus-
tion circuit and the relevant seals,
- that any defects have been corrected at this stage.
Proceed to put the boiler into operation as follows:
• Start the boiler by activating the test program P.1. as
described in section 9.4.
• Check for tightness of the flue gas system as detailed
in 6.5.1.
• Check the gas inlet working pressure as detailed in
6.5.2.
• Check the maximum gas flow rate as detailed in 6.5.3.
• Please note that you must re-measure the gas flow
rate or the gas inlet working pressure, if changes were
required to correct any issues found.

on the system
6.5.1
Checking for tightness of the flue gas system
Caution!
a
Caution! Risk of malfunction!
The combustion air must be free of particles or
the burner can be contaminated with dirt.
Take particular care that no building dust, fi-
bres of insulating material or pollen is present.
• Check the integrity of the flues system according to
TB 008 (Edition 2) and TB 017.
• Check entire length of the air and flue gas system for
correct installation to ensure that
- there are no blockages,
- all joints are sound,
- the fall angle is correct
- it is adequately supported
all in accordance with the relevant flue installation in-
structions.
• Correct the defects.
