b) Replacement of ignition burner nozzle
Access to the ignition burner is possible only after removing the control panel.
Remove the closing nut from the ignition burner and replace or adjust nozzles
of the ignition flame accordingly to the gas type.
c) Primary air adjustment (fig. 2)
When the primary air is adjusted correctly the flame is
stable, so there will be no interruptions when the burner
is cold or back burning when the burner is hot.
The provided distance (“X”) for the primary air setting is
specified in
fig. 2
and in
table 2
. After the replacement of
nozzles check setting of primary air for all burners.
