The maintop burners have spark ignition operated by a switch on each control valve. When any burner control knob is pressed
in the spark generator module produces sparks at all the burners ignition electrodes.

The ignition system
makes sparks but does
not light the gas
Try lighting the burner with a match.
Are the flames even around the head with a blueish color?
Check the burner head is clean and the flame ports are clear. Check that the burner head is
sitting down correctly on the burner base.
What gas is being used? The range is supplied set for Natural Gas. It must be converted before
it can be used on LP gas.
The ignition system
does not make sparks
Use flow chart (page 6) to check out the ignition system.
The burner lights but
the flame goes out
when the control knob
is released
Each burner gas control valve includes a thermoelectric solenoid flame safety valve (FSD)
that is normally closed. There is a sensor probe mounted on each burner. To light a burner
the user must push in the control knob and turn to the full on position. Pushing in the knob
overrides the safety valve and allows gas to flow to the burner while the knob is pushed in.
The spark ignition lights the burner and the flame heats the sensor probe. When it gets hot
enough the sensor produces a very low voltage electric current that keeps the safety valve
open when the control knob is released.
Try holding the knob in for longer. The FSD should hold in after a few seconds, if it does not
hold in after 10 seconds the sensor may not be getting hot enough because there is problem
with the burner head or the sensor position is incorrect.
Check the burner head is clean and the flame ports are clear. Check that the burner head is
sitting down correctly on the burner base.
If this does not solve the problem try changing the sensor probe.
The burner flame goes
out when the control
is turned to low
Check that the burner control valve is fitted with the correct bypass screw. See the ‘Technical
Data’ section at the end of this book.
Try changing the bypass screw for a new one.
The burner flames are
very yellow
What gas is being used? The range is supplied set for Natural Gas. It must be converted before
it can be used on LP gas.
The burner flames are
very small and blue
What gas is being used? The range is supplied set for Natural Gas. If it has been converted for
use on LP gas it must be reconverted by changing the burner orifices and control valve bypass
screws before it can be used on Natural Gas.
The pattern of flames
on the burner is not
even
Check the burner head is clean and the flame ports are clear. Check that the burner head is
sitting down correctly on the burner base.
