3. Screw fixing studs for operating mechanism from below into the valve mounting
flange . Put gasket onto the sealing face of the operating mechanism. Attach
gasket and operating mechanism to valve mounting flange by fastening the nuts of
the fixing studs, torque required for tightening 90 Nm.
4. Place tappet guide onto valve mounting flange and pass tappet through
guide.
5. Check correct position of tappet (specified setting 23 ± 0.5 mm) from inside of
tank. When checking, make sure that the lever of the operating mechanism is
