Fourth test phase
In the fourth test phase, the joint to the mixing head 1 is tested for soundness. The
test phase can only be carried out during or after burner commissioning.
A leak detecting spray or electronic gas detector should be used for testing.
Use only leak detecting foam solutions, which do not cause corrosion, see DVGW-
TRGI, worksheet G600.
Check all components, intersections and test points of the gas valve train
between multifunction assembly and burner.
Document result of the soundness test on the engineers report.
