• 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 (E01) and, in
the meantime, check the pump release.
• 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 72 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 17 (Fig.
7.4) key until the message OFF appears on
the LCD display (Fig. 7.3).

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-
