It is advisable to check the following before turning on the boiler for the first time:
– Check that there are no liquids or flammable materials in the immediate vicinity of the boiler.
– Check that electrical connections have been made correctly and that the ground wire is connected to a proper
grounding system.
– Open the gas cock and check the seal on connections, including the burner connection.
– Check that the boiler is set up to run on the type of gas available.
– Check that the flue through which the products of combustion are eliminated is free.
– Check that gate valves are open, if there are any.
– Check that the heating system has been filled with water and air has been bled out of it.
– Turn on the circulation pump, unless it is commanded by an automatic system.
– Bleed air out of the gas pipe using the pressure intake bleed valve located on the gas valve inlet.
– Check that none of the regulation, control and safety devices have been tampered with.
NOTE: When turning the generator back on, or if the boiler has not been used for some time, it is advisable to
bleed gas pipes for air. If this is not done, burner ignition may be delayed, possibly causing the boiler to shut
down. Wait at least 20 seconds from the time the indicator light comes on before releasing it.
If there is no voltage, the burner will shut down immediately. When the voltage is restored, the boiler will start
functioning again automatically. If gas pressure is insufficient, the device will shut down immediately, and the
signal for shutting down the equipment and the red gas pressure indicator light will come on.
If this occurs, the boiler cannot be started up using the device's release button, for safety reasons. The boiler
will be ignited automatically when the pressure returns to the minimum pressure setting on the gas pressure
switch (10 mbar).
