Flashbacks
A flashback is an explosion of the premixed gases in the burner chamber. The safety interlocks
normally prevent conditions that could cause a flashback, but if a flashback should ever occur:
•
Check that the burner head slot is clean.
•
Check that the burner head is seated correctly.
•
Check the flow spoiler or impact bead for damage, and replace any damaged parts.
•
Make sure that you are using compressed air and not oxygen enriched air.
•
Carefully check and tighten all connections to, and seals on, the burner unit, and check the
gas flow settings before you attempt to ignite the flame. Seepage of fuel and oxidant from the
burner chamber may cause a flashback.
