PILOT FLAME CHARACTERISTICS (continued)
Cleaning and Maintenance/Pilot Oxygen Depletion Sensor Pilot (Figure 20)
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 out 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.
