11.12 Measure ionisation current
See chapter 8.10 "Measure ionisation current".
11.13 Testing for gas leaks
See chapter 8.11 "Testing for gas leaks".
11.14 Check for correct operating characteristics
 Check all fittings for leaks.
 Check water pressure of wall mounted gas condensing boiler and top
up if necessary.
In doing so, take the water quality into account ( Chapter 5.2).
 Check the settings of the wall mounted gas condensing boiler
( Chapter 7.2 "Setup menu").
 Close the casing and tighten the retaining screws.
