BURNER: may backfire and partially ignite.
If there are flame returns, immediately close the gas supply (cylinder or domestic line) and
turn off the fire. Probably the venturi tube has obstructions that must be removed, even
simple cobwebs can compromise its operation. If the flame front does not burn completely
over the entire length of the burner in addition to not heating well, crackles or flame returns
may occur; in this case make sure that all the burner holes are free and not obstructed by
food residues from previous uses. If previous adjustments or injector replacements have
been made, make sure that the air/gas carburation is correct for optimal operation. It may
also depend on fitting an incorrectly sized calibrated hole injector to the gas used. If there
are no obvious obstructions, the holes are regularly opened and the carburation is regular
but the problems still exist, it may be necessary to replace the entire burner as it is defecti-
ve or worn. (See dedicated section for part replacement). If regularly maintained, cleaned
and used correctly, its duration over time is considerable.
Have a technician perform the control and maintenance operations. Some malfun-
ctions may also depend on the incorrect positioning of the sensors on the burner. If the
thermocouple is not at the correct distance from the support on the burner, it could misre-
ad the temperature and not work properly or wear out quickly and have a short life cycle.
The same applies to the ignition spark plug, if it is too far away it may not be able to release
the spark to ignite the burner or if it is brought into contact with the burner the pulse is
discharged without generating the spark.
