Clean off all fingerprints on quartz parts before installing them. This prevents premature ageing of
quartz parts. Use acetone, for example, for cleaning.

Phase 1: Installing reaction tubes
Proceed as follows:

Close the Reductor (6) with the plug (5) and well as with the bottom plug.

Close the combustion tube (4) with the combustion tube connector (3).

Close the post combustion tube (2) with the plug (1).

Insert the reaction tubes into the furnace:

Insert the combustion tube (4) in the middle, as seen from the front; the combustion tube
fixing pin (5) must snap into the holder (6).

Insert the Reductor (6) on the right, as seen from the front.

Insert the post combustion tube (2) on the left, as seen from the front.

Check that the reaction tube comes to rest on the bottom of the holder. The holders are
height-adjustable so as to allow for reaction tube length tolerances.

Install the quartz glass bridge between the combustion tube outlet and the post combustion tube
inlet.
