DANGER
While attaching the flexible gas hose to the burner, the connec-
tion adapter must be held with an open-ended spanner SW 36.
The connection adapter must not get twisted vis-a-vis the burner
casing. The threaded connection should only be sealed using a
sealant approved by DVGW. After connection, the joint must be
checked for leaks using a DVGW-approved leak detector spray.
