Vent valve and standpipe (internal gas balance pipe)
– continued –
10. Use operating rod to open the vent valve . Fix it in place by inserting a
suitable fixing pin (
∅
4 mm) into the hole above the guide .
Pass connecting rod into the guide pipe of the bayonet base cap and
screw it into the connecting sleeve by turning it to the right until the
adjustment setting 30
±
1 mm is attained. Tighten lock nut , remove fixing
pin and close the vent valve .
Checking the adjustment
The square piece has to protrude 15 + 2 mm from the guide pipe.
It must be easily possible to push the complete operating rod assembly
(connecting rod and operating rod weigh approx. 8 kg) smoothly approx.
6 mm upwards (vent valve does not open yet, i. e. idle lift).
If this is not possible modify the adjustment setting in such a way that the
specified setting (15
+2 mm) is maintained and the idle lift of the valve
(6
±
0.5 mm) is also taken into account. Secure the bayonet base cap by
using hexagon-head bolts M8 x 40 and nuts M8 .
