•
Ensure the CONTINUOUS PILOT switch on the control module (Fig. 60) is set to
OFF.
•
Verify the gas supply is turned on.
•
Ensure the pilot flame will ignite. If not, see pilot flame troubleshooting above.
•
Make sure the green and white leads from the module are securely connected to
the terminals labeled “MAIN: on the valve body. (Fig. 62)
•
Make certain the pilot flame is in contact with the flame rectification sensor on the
pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig.
62) If the pilot flame is too small it will not contact the flame rectification sensor
and will not complete the safety circuit.
•
Ensure the pilot flame is properly located to ignite the main flame.
•
Check continuity of main burner coil in gas valve. Remove wire connector. If there
is no continuity, replace valve.
