-Ensure connections are watertight.

-Vent the tank heat exchanger as follows:

1.Unscrew the auto vent cap (P)* a few turns.

2.Turn the antisyphon valve screw 10 to open position (O)

3.Close the vent (P)* when water flows continuously.

4.Return the antisyphon valve screw 10 to the automatic position (A)

5.To vent the pump, unscrew the protection cover in the pump head and turn the pump shaft (V) left and right a few times.

6.Leave the pump running with cold water for a few minutes to prime the system.

5.1 Starting Up

Initial starting up shall be performed by a qualified professional.

•Make sure that safety thermostat 6 is set by unscrewing the hexagonal cap and pressing the reset button with a screwdriver.

•Turn On/Off switch 1 to On .

•Turn burner switch 2 to Winter .

If the boiler is fitted with an MB1 domestic hot water module, this switch is disabled by the optional unit.

Turn heating pump switch 3 to Winter .

Note: We advise you never to set the boiler thermostat below mark 4 (40ºC) in order to avoid the risk of combustion products condensing on the walls of the boiler.

Before turning the boiler on, make sure that the installation is filled with water.

Perform the start-up operations in the chronological order given below, referring to the diagram on page 14.

•Set boiler thermostat 7 to the selected position (move the stop if required).

WARNING

IMPORTANT: if the boiler is fitted with a room thermostat, set boiler thermostat 7 to the maximum position.

•Set the domestic hot water temperature setting potentiometer to the desired temperature (versions with MB1).

•Check the position of three-position switch 5, which must be as follows:

-either set to manual : boilers without room thermostats

-or set to AUTO (automatic): boilers with room thermostats.

5.2 Commissioning Secondary Circuit

•If needed, flush the sanitary circuit (especially if re-starting) and fill the tank using the sanitary cold water inlet pipe.

•Bleed the secondary circuit (tank and distribution system) in order to avoid any noise caused by trapped air moving during re-heating and drawing off. To do this, fill it completely with water, leaving a hot water tap open; close this tap only when the flow of water is continuous and noise-free.

•Then bleed in succession all hot water pipes by opening the corresponding taps.

•Bleed the tank's exchanger circuit using the vent made for the purpose.

•Check all safety units (especially the safety valve or group) referring to the leaflet supplied with the component.

WARNING

During the heating of domestic hot water, some water may escape through the safety valve or group as a result of the expansion of water in the unit. There is no cause for concern as this is entirely normal. Do no attempt to prevent this from happening
