Please refer to the Instructions delivered with the waterheater

Start-up recommendations (l)

Please refer to the instructions which are delivered with the waterheater.Power supply 230V Live/Neutral. (Do not reverse polarity).Room thermostat connection.

Work on the pump motor shaft to unlock it if it were jammed.Manually vent the boiler.Fill the primary loop (if no DHW cylinder has been installed) slowly until the pressure reaches14.5 - 29 PSI / 1-2 bar. (If a DHW cylinder has been installed, then fill the secondary loop first).Open the DHW circuit for it to fill up and ventWith the gas inlet cock still closed, program the Heating mode. The boiler will perform a lightingcycle and will then lock out under code 60-70-90.Leave it like that for five minutes so that the pump, which is still running, can help vent the circuit.

Next, check the pressure level and top up if it has dropped to 14.5 PSI / 1 bar.Open the gas inlet cock, reset the system (code 60-70-90) and the boiler will start operating.Allow the waterheaterto operate in the Heating mode for ten minutes, during whichcheck that allradiators warm up. Should one radiator fail to warm up, bleed the air in it. But if it still does notwarm up, then the flow rates in all radiators should be balanced, always optimizing the pumpperformance curve (flow rate/pressure) through its speed selector control.Open the DHW tap with the highest flow rate in the house. The waterheaterwill operate for ten minutescontinuously at full output (79,366 Btu / 20,000 kcal/h). If the flue spillage detection thermostat does

not trip, that means that the removal of flue gases is correct.If a gas meter is available, check the gas input rate, as indicated in the waterheater Instructions



9/56


Where a water column is available, connect it to the gas valve pressure test point and check theworking pressure with the waterheateroperating at full output (79,366 Btu / 20,000 kcal/h).Program the Heating mode again.

Program the DHW mode again. For a higher level of comfort, particular ly where substantialpressure variations in the water supply occur, set the program close to the draw-off temperature.Remove the water column, replace the plug and washer, start the system, and using soapy watercheck the whole circuit for gas tightness.Ensure that the waterheaterroom has a proper ventilation and air renewal system.

Instruct the user on the following points:Recommend him/her to read the Users Instructions.

Instruct him/her on how to program the Heating and DHW temperature and the roomthermostat (if any).Instruct him/her on how to fill and/or top up the Heating system.Demonstrate how the fault codes work for insufficient gas (60-70-90 and 40-80-90) and how toreset (R) after opening the gas inlet cock or changing the gas cylinder.Recommend him/her to turn the selector switch to the R position whenever a red fault lamp lights up.If the red light appears two or three consecutive times, tell the user to write down the number of thetemperature LEDs which light up and then to notify the nearest Service Centeror Installer.

Train him/her on the various safety devices, recommendations and maintenance operations specifiedin the waterheaterInstructions.


Start-up recommendations (lI)


10/56


It should be ON

It should be between 14.5 and 29 PSI / 1 and 2 bar

Fill and/or top up if pressure is less than 14.5 PSI / 1 bar

Maintenance

Carry out the following maintenance operations at least once a year, and preferably at the beginningof the Heating season:DHW

Clean the cold water filterCheck the DHW temperatureHeatingCheck the system pressureCheck the waterheaterwater temperatureCheck the pump operationBleed the air in the radiators and boilerCheck the room thermostat

Check the safety valveGasCheck the burner setting pressureCheck the input rateCheck the circuit for gas tightnessClean the burner VenturisCombustion and VentilationCheck the flue duct tightness

Check the effectiveness of ventilation and air renewal system. Ensure there are no obstructions.Conduct a flue gas analysis.
