WORKSHOP MANUAL
13�7�4 Test of burner ignition
When testing the burner ignition, check the behaviour of the
burners and the position of the gas flame.
The behaviour of the burners when ignited is correct if the burn-
ers ignite within a few seconds.
Unless the burners ignite within a few seconds, the ignition box
stops further attempts for igniting the burners and interrupts
gas supply.

Insert the key into the ignition box (11) in the position “0” and
switch over to the position “I”.
Set the key between position “I” and “II” and the engine glowing
