7.Activate "ON mode" by going through the following steps:

-Press once on the blue arrow () to position the cursor beside ON,

then press .

-Confirm the selection START OPERATION with .

8.If there is no heat demand, increase Tset (11.4 "Setting the water temperature"). Note the original setting. Draw some hot water off to create heat demand.

9.Check whether the heating cycle runs correctly (9.3 "The appliance's heating cycle").

10.If you have adjusted Tset , return it to the desired value (11.4 "Setting the water temperature").

11.Remove the plastic cover on the top of the appliance.

12.Check the supply and burner pressure (3.11 "Checking the supply pressure and burner pressure"), and adjust them if necessary.

13.Check that all components of the chimney flue system are properly attached.

14.Check the pressure differential across the orifice plate of the pressure switch (see the table). If the pressure difference is too low, the heat exchanger must be cleaned (15.4.4 "Cleaning the heat exchanger").
