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 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 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).
