Remove the three phillips screws from the group head boiler.

Using your needle nose pliers remove the locking clip pins from the boiler tubes and the pressure dial from the front panel.

Use the needle nose pliers to remove the yellow leads from the boiler also.

You may wish to mark each tube prior to the next step.

Now remove the tubes and leads from the boiler. You will not need to remove the two red leads, 1 blue lead and the black leads as these can easily be kept with the boiler when moving it to the rear of the machine
