7.3 Installation
WARNING!
Risk of injury due to improper installation!
Failure to observe the tightening torque value is dangerous due
to the risk of damage to the device.
▶ Use an open-end wrench for installation, never a pipe
wrench.
▶ Observe tightening torque (see "Tab. 7: Tightening torques
valve body/nipple").
Dirt trap for devices with approval according to DIN EN 161
According to DIN EN 161 "Automatic shut-off valves for gas burners
and gas appliances", a dirt trap, which prevents the penetration of
a 1 mm test pin, must be installed upstream of the valve.
→ If the approval also applies to the stainless steel valve body,
such a dirt trap must be attached in front of the globe valve.
