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.
The water heater leaves the factory pre-set and tested for burning either natural Gas or PROPANE.
Nevertheless, when starting the water heater for the first time, make sure that the information on the
rating plate corresponds to the type of gas being supplied to the water heater.
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 water heater on for the first time means checking that the installation, regulation and operation of the
appliance are correct:
• Check that the data on the rating plate corresponds to that of the mains supply networks (gas, electricity, water));
• Check that the power supply voltage to the water heater complies with the data 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 water heater 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 water heater (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 water heater;
• Flush out both primary and domestic hot water circuits (see 4.3 "Flushing the system").
