Approximately 1.5 cm of the large ceramic tube should extend above the top
of the quartz heater assembly. Slide a 1/4" Swagelok nut over the large
ceramic tube and then also slide a 1/4" ferrule over the tube (flat side on
back of the nut).
9 Holding the splitter fitting, gently insert the upper ceramic tube into the
large ceramic tube coaxially, to avoid placing stress on the fragile upper
ceramic tube. Lower the splitter fitting into place to engage the threads of
the 1/4" Swagelok nut. Tighten finger-tight.

the flats of the tapered union fitting, tighten the heater swivel nut
one-quarter turn past finger-tight. Using a 5/16" wrench on the 1/4" Burner
