WARNING!
Risk of injury from improper installation!
Assembly with unsuitable tools or non-observance of the tight-
ening torque is dangerous as the device may be damaged.
▶ For installation use an open-end wrench, never a pipe wrench.
▶ Observe the tightening torque (see "Tab. 5").
Dirt trap for devices with authorisation in acc. with DIN EN 161
In accordance with DIN EN 161 "Automatic shut-off valves for gas
burners and gas appliances" a dirt trap must be connected upstream
of the valve and prevent the insertion of a 1 mm plug gauge.
