5. COMMISSIONING THE APPLIANCE (Authorised Service)
5.1 General Warnings
The following operations must be carried out by professionally quali
fi
ed personnel, registered in
accordance with current legislation.
The boiler leaves the factory pre-set and tested for burning natural gas. Nevertheless, when start-
ing the boiler for the
fi
rst time, make sure that the information on the rating plate corresponds to
the type of gas being supplied to the boiler.
Once the system has been
fi
lled and the necessary adjustments made, remember to tighten the
screws of the gas valve test point and make sure that there are no gas leaks from the test point
and from any pipe
fi
ttings upstream of the gas valve.
Preliminary Operations
Switching the boiler on for the
fi
rst time means checking that the installation, regulation and operation of the
appliance are correct :
●
If the gas supply system is newly installed, then the air present in the pipes can cause the boiler not to light
at the
fi
rst attempt. A number of attempts may be required in order to light the boiler;
●
Check that the data on the data plate corresponds to that of the mains supply networks (gas, electricity,
water);
●
Check that the power supply voltage to the boiler complies with the data plate (230 V – 50 Hz) and that the
live, neutral and earth wires are connected properly. Also make sure that the earth connection is sound;
●
Check the seals on the gas supply pipe from the mains, and make sure that the meter does not register
any
fl
ow of gas;
●
Turn the gas supply on and purge.
●
Test for gas soundness.
●
Check that the gas supply is correctly sized for the
fl
ow rate required by the boiler and that it is
fi
tted with
all the safety and control devices as lay down by current regulations
●
Check that the supply of combustion air and exhaust and condensate discharge systems are functioning
correctly and in line with current law and national and local standards;
●
Check for the presence of permanent aeration/ventilation openings as required by current law for the type
of appliances installed.
●
Check that the
fl
ue duct and its connections to the terminal/chimney comply with the requirements of cur-
rent law and national and local standards for the type of appliances installed.
●
Make sure that any central heating shut-off valves are open.
●
Check that the condensate drain system, including outside the boiler (
fl
ue system condensate collection
devices), allows the condensate to
fl
ow freely to the collection devices. If the condensate is discharged to
the domestic drainage system, install an inspection trap in the condensate system prior to it entering the
drainage system to interrupt the continuity between the two systems.
●
Check that there are no exhaust fumes discharged into the system itself.
●
Check that there are no
fl
ammable materials or liquids in the immediate vicinity of the boiler;
●
Flush out both primary and domestic hot water circuits (see 5.3 “ Flushing the system”).
