▶ Remove securing screws [3] to detach the terminal assembly from
the turret.
▶ Slide terminal section [2] from the terminal assembly [1] and
discard the terminal section [2].

Further flue length reduction of the terminal assembly:
▶ Mark the length required for the terminal as shown (min. 130mm)
and cut square, taking care not to damage the tubes.
▶ Remove any burrs and chamfer the outer edge of the tubes to assist
ease of connection and prevent seal damage.
