Parts Number: 016-43201-02 Polyethylene Tube, 8 × 1 (for Drain Tube)

When the drain tube becomes old it may rupture, allowing drain to leak out. Replace the drain tube by following the procedure below.
1. Remove the old polythene tube connected to the outlet of the drain tank.
2. Connect the new polythene tube.
3. Prepare a container to receive the drain from the instrument.
4. Cut the polythene tube to the appropriate length.
  Make sure that the end of the tube is not submerged in the waste liquid in the container.
5. Supply water a little at a time through the burner socket until water overflows from the drain tank. If the water level is too low the liquid level sensor actuates and ignition will not be possible.

CAUTION: Be sure to lower the drain tube as smoothly as possible. Also ensure that the end of the tube is not submerged in the waste liquid in the container.
  If the waste liquid cannot flow smoothly the level of noise will be increased and this may have an adverse affect on repeatability.
