Frequently Asked Questions - DE2427555 SIEMENS

How to turn on the DE2427555 boiler?

Make sure gas and electricity are connected. Turn the mode knob to 'summer' or 'winter' as needed. The burner will ignite automatically.

What to do if water pressure is too low?

Check the pressure gauge: pressure should be between 1 and 2 bar. If too low, open the filling valve until 1.5 bar is reached, then close.

How to bleed the radiators?

Use a bleed key on the radiator valve. Place a container under the bleed valve, turn the screw until you hear a hiss and water flows. Close when no more air.
