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.

Warning:

Never use needles, wires, or similar cylindrical objects to clean

the pilot to avoid damaging the calibrated ruby that controls

the gas flow.

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.
