Checking the equipment function

After installing and checking the gas supply pressure,
perform a function check before commissioning the ap-
pliance and handing over to the user.
• Commission the appliance in accordance with the in-
structions in the relevant operating manual.
• Check the gas infeed, exhaust gas installation, boiler and
heating installation and the hot water pipes for leaks.
• Check the flue pipe for proper installation.
• Check over-ignition and that the flame on the burner
is burning evenly.

and the hot water preparation (see Chapter 6.3.2)
• Hand the unit over to the user.
The Vaillant ecoTEC exclusive has status codes which
indicate the operating condition of the appliance in the
