BURNERS
■ These parts can be removed and cleaned with appropriate products.
■ After cleaning, the burners and their ame spreaders must be well dried and correctly
replaced.
■ Check that the electrode/s “S” (gs. 15a, 15c, 15d) next to each burner is/are always
clean to ensure trouble-free sparking.
■ Check that the probe/s “T” (gs. 15a, 15c, 15d) next to each burner is/are always clean
to ensure correct operation of the safety valves.
■ Both the probe and ignition plug must be very carefully cleaned.
■ Note: To avoid damage to the electric ignition do not use it when the burners are
not in place.
CORRECT REPLACEMENT OF THE AUXILIARY, SEMI-RAPID AND RAPID
BURNER (the rapid burner is available for the model NSL 590D NCM only)
It is very important to check that the burner ame spreader “F” and the cap “C” have been
correctly positioned (see gs. 15a and 15b). Failure to do so can cause serious problems.
■ They shall be level and the ame spreader must not rotate.
CORRECT REPLACEMENT OF THE DOUBLE-RING COMPACT (model
NSL 460 NCM) AND DOUBLE-RING BURNER (model NSL 590D NCM)
It is very important to check that the burner ame spreader “F1” and “F2” and the caps
“A”, “B” have been correctly positioned (see gs. 15c, 15d, 15e, 15f). Failure to do so can
cause serious problems.
■ Fit the ame spreader to the housing: the burner ribs must be tted in their housing as
shown by the arrows (see gs. 15c, 15d).
■ Then position the cap “A” and the ring “B” (see g. 15e).
■ They shall be level and the ame spreader must not rotate (see g. 15f).
