Phase 1: Installing reaction tubes
Proceed as follows:
 Close the reduction tube (6) with the plug (5).
 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 reduction tube (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.
