How to handle the burner insert:
- Always remove electordes (18) first while
dismounting burner insert.
- Tighten fuel nozzle (17) only with a
hexagonal wrench and a torque of 18 Nm.
Otherwise the fuel nozzle can be damaged
and a proper combustion can’t be
guarantied.
- Always measure the electrode (18) set-up
first and re-adjust if necessary before re-
installing burner insert (values see Pic.
6.26 and 6.27).
