•
Make sure that the ambient thermostat is in
the “heat demand” position.
•
Check that the boiler with the gas cock shut-
off goes into ignition lockout (Er01) and, in
the meantime, check the pump release.
•
The pump release can be verified by check
-
ing that the pump motor vibrates.
•
If the pump motor does not vibrate, release
the boiler from its lockout due to gas failure
by pressing the reset button on the control
panel and repeat the sequence a maximum
of 10 times.
•
If the pump does not release, contact techni
-
cal support.
•
Once the pump has been released, open
the gas cock and check that the boiler op
-
erates correctly both in domestic hot water
and heating modes.
•
Check the gas pressures and flow rates as
shown in section "GAS CONVERSION" on
page 74 of this booklet.
•
Check that the condensate produced during
functioning fills the syphon
and is regularly
drained in the
draining pipe
.
•
Switch off the boiler by pressing the 16 (Fig.
7.4) key for 2 seconds until the
sym
-
bol appears on the LCD display (Fig. 7.3).
7.6 Condensate pipe and traps
The full length of the condensate pipe should
be check for leaks.
Before running the boiler, ensure that the built
in condensate trap and any other trap in the
drain system is correctly filled with water.
Fill the built in condensate trap by
removing the flue elbow and pour
-
ing a cupful of water into the flue
outlet (Fig. 7.6).
Warning do not allow water to en-
ter the outer air intake

An alternative, to the removal of the flue el
-
bow, pour the water through the flue sampling
point (Fig. 7.7).

7.7 Checking the gas supply pres-
sure
This boiler has been factory tested to the
highest quality control standards and set
for the minimum and maximum gas work
-
ing pressures, connected to a 1 m flue and
a gas supply pressure of 20 mbar.
Any variation in gas supply pressure or
flue length may result in the customer ex
-
periencing a harmonic noise from the boil-
er. In these circumstances, it may be nec-
essary to reset the burner gas pressures
in accordance with section 11 Gas Valve of
the Service Manual.
It should be noted that a Flue Gas Analyser
is required for this procedure.
