4. STARTING UP THE WATER HEATER (authorised personnel)
4.1 General warnings
The following operations must be carried out by professionally qualified personnel authorised by
Radiant Bruciatori s.p.a.
The water heater leaves the factory pre-set and tested for burning either natural Gas or LPG.
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.
4.2 Preliminary operations
Switching the water heater for the first 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 water heater not to
light at the first attempt. A number of attempts may be required in order to light the water heater.
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 water heater 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
flow of gas.
Open the gas valve to the water heater and check that there are no leaks from the fittings upstream of the water
heater (the burner gas connection is checked with the water heater in operation).
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 as lay down by current regulations.
Check that the supply of combustion air and exhaust are functioning correctly and in line with current law and
national and local standards.
Check that the flue duct and its connections to the terminal/chimney comply with the requirements of current
law and national and local standards for the type of appliances installed.
Check the presence of air intake/permanent ventilation openings correctly sized according to the water heater
installed and in respect with current law.
Check that there are no exhaust fumes discharged into the system itself.
Check that there are no flammable materials or liquids in the immediate vicinity of the water heater;
