When the heat cycle is over all burners will be off. CONTINUOUS PILOT BURNER SEQUENCE OF OPERATION S/N 2611 to 7183 120V power is supplied to the primary side of the transformer. 24VAC comes off the secondary side of the transformer which provides power to the over-temp / solder washer assembly. Once the ON/ OFF switch is set to the ON position, power is applied to the ignition module through the blue wire and back out the red wire to the main gas control valve. -

Page 16: Testing - Flame Sense
TESTING FLAME SENSE MEASUREMENT The ACCU-STEAM gas griddle has a flame sensing circuit to determine if the system has proper combustion. When the system is turned on gas is sent to the pilot burner and an electronic ignition tries to ignite the griddle. The griddle then checks to see if flame is established in the pilot burner. - Page 17 Set multi-meter to DC mv. Connect Flame Tester leads, to Igniter Harness Orange (or yellow) and Green wires. Verify your reading is above 60 DC mv and the system will shutdown below 19 DC mv. SP8016-1005 ACCU-STEAM SERVICE MANUAL PAGE 15...
