Our Company declares that RS MkII boilers comply with the essential requirements of the following direc-
tives:
- Boiler Efficiency Directive 92/42/EEC
- Gas Appliances Directive 2009/142/EC
- Electromagnetic Compatibility Directive 2014/30/UE
- Low Voltage Directive 2014/35/UE
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 groun-
ding 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
functioning again automatically. When the gas pressure is insufficient, the burner immediately turns off and the
insufficient gas pressure warning signal is enabled.
If this occurs, the boiler cannot be started up using
The boiler will be ignited automatically when the pressure returns to the minimum pressure setting on the gas pres-
sure switch (10 mbar).
CHARACTERISTICS OF THE SYSTEM SAFETY VALVE: calibration pressure: 5 bar; maximum generator power: 373.4
Kw, 3/4" x 1" fixtures (see Caleffi catalogue, code 527550).
