PILOT FLAME CHARACTERISTICS
The correct flame will be blue and will extend beyond the thermocouple. The flame will surround the thermocouple just below the tip. A slight yellow flame may occur where the pilot flame and main burner flame meet.
Figure 17
Oxygen Depletion Sensor Pilot (Figure 16)
When the pilot has a large yellow tip flame, clean the Oxygen Depletion Sensor as follows:
1.Clean the ODS pilot by loosening nut B from the pilot tubing. When this procedure is required, grasp nut A with an open end wrench.
2.Blow air pressure through the holes indicated by the arrows. This will blow our foreign materials such as dust, lint and spider webs. Tighten nut B also by grasping nut A.

Warning:
Never use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow.
