Fitting the extended work tube in a furnace
Tools required: 4 mm Allen key
The fitting of the work tube is as follows with reference to Figure 2.3.5. Extended work
tubes are 450 mm longer than the heated length of the furnace (see the table in section
11.0). Read section 7.2 before fitting the work tube.
Note it is easier to fit the work tube with the furnace in the horizontal position as shown
in figure 2.3.4.
To fit the work tube in a vertical orientation follow the steps below. Omit the use of the
end seal if not required. The same tube support design will work with or without the
tube end seal in place.
WARNING - If clamps are used without an end seal, care should be
taken not to over tighten on to a bare tube, especially if the tube is
either quartz or thin wall section.

Before the extended work tube can be fitted, the work tube end stops for the stand-
ard length work tube must be removed from both ends of the furnace. This is done
by removing the furnace end guard (8) and the work tube adaptor brackets (4) to
release the work tube end stop. The guards and brackets should then be refitted.
