c) Put in position the pressure detector directly on the burner injector afterward open the relative burner
knob at maximum position keeping it pressed, then measure the outlet pressure from the burner
injector.
d) Once the pressure checking has been carried out, replace the burner cap and flame spreader in the
correct and original position and re-connect electric power to the appliance.
8. Turn on appliance control cock and light each burner. Check for a clear blue flame without yellow tipping.
If burners show any abnormalities check that they are located properly and in line with the injector nipple.
9. Sometimes the burners will not ignite immediately and seem to 'blow' slightly when they do ignite. This
usually due to air in the gas lines, which will clear itself within seconds.
10. If after following the instructions given, satisfactory performance cannot be obtained, contact the local
gas authority for advice and assistance.
Electrical connection
The appliance is equipped with a 4 ft. (1.2 m.) flexible metal cable with 4 wires ready for connection to a
dedicated 4 wire grounded power supply/junction box: (fig.13)
Voltage 120/208 V a.c., Frequency 60Hz. Max Current: 3600W /20,2 A
Voltage 120/240 V a.c., Frequency 60Hz. Max Current: 4500W /22,2 A
A dedicated line and junction box should be used to connect the oven to a 25 A circuit.
