Service manual April 2017 Uber boiler
To remove the Uber Font Dial and spindle connected to the Font head ball valve, loosen the
grub screw, accessible from the centre of the Dial.
If the ball valve is found to be dripping/leaking, check that the spindle is not worn, allowing
the ball valve to rotate past the Off position.
When refitting the ball valve/nozzle assembly, use the nylon slide bearing on the spindle to
centre the assembly before tightening the fittings.
