Checking flame current
 The minimum value should be in accordance with specified
value.
 To check flame current connect a DC micro--Ampèremeter
between flame sensing wire and flame sensing rod.
 If flame current is insufficient check that flame sensing rod
is fully enveloped by the flame and that burner is reliable
grounded to the ignition control.
 If there is no sufficient flame current due to phase--phase
mains it is recommended to use an ignition control with the
phase neutral independent operation feature. If this is not
available, it is recommended to use a AT7030A or
AT7030B flame detection transformer. See also instruction
sheet EN1R--9136 for the AT7030 transformer.
WARNING
Short ←A meter during ignition to prevent damage of
the ←A meter in single rod application.
FINAL CHECKOUT
Final checkout of the installation
Set appliance in operation after any adjustment and observe
several complete cycles to ensure that all burner components
function correctly.
