4. COMMISSIONING THE APPLIANCE
4.1 General warnings
The following operations must be carried out by professionally qualified personnel, registered in
accordance with current legislation.
Use of a properly calibrated electronic combustion analyzer MUST be used when installing,
servicing or converting this Boiler from Natural Gas to LP or from LP to Natural Gas.
The boiler leaves the factory pre-set and tested for burning either Natural Gas or LPG. Nevertheless,
when starting the boiler for the first 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 filled 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 fittings upstream of the gas valve.

Preliminary operations
Switching the boiler on for the first time means checking that the installation, regulation and operation of the
appliance are correct:
Check that the rating on the rating plate corresponds to that of the mains supply networks (gas, electricity,
water));
Check that the power supply voltage to the boiler complies with the rating plate (120 V
– 60 Hz) and that the live,
neutral and ground wires are connected properly. Also make sure that the ground connection is sound;
Check that the gas supply is correctly sized for the flow rate required by the boiler and that it is fitted with all
the safety and control devices stipulated 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 exhaust vent and its connections to the termination comply with the requirements of current 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 (exhaust system condensate
collection devices), allows the condensate to flow freely to the drain.
Check that there are no flammable materials or liquids in the immediate vicinity of the boiler;
Flush out both primary and domestic hot water circuits (see 4.3
“Flushing the system”).
