or third time.
Burner flashes
back Flashbacks can be caused by any of
the reasons listed below. Carefully inspect the burner
system for possible causes,
referring to the ones listed
below. Reignite the flame only
after the problem has been
corrected. Contact a
PerkinElmer service
representative for assistance.
Fuel and oxidant gas lines may have
been inadvertently switched. Check the connections at the
burner and at the gas supplies.
The burner system may leak. Check the condition of all
o-rings (burner head, end cap,
o-ring on nebulizer front end
cap). Replace o-rings that show
signs of wear (cracking,
swelling). Inspect the inner
surface of the burner chamber
for pitting and replace if
necessary. Check drain
connections for leaks.
