Open Top Burner Pilot Adjustments

Tools: Standard screwdriver.

valve adjustment screw provided on the manifold pipe. Turn the burner ON; burner flame should appear

on the burner head within a second. Rotate the screw clockwise to decrease and counterclockwise to

increase the flame.

Check the open top burner nozzle relationship. The burner nozzle should enter approximately

inside the burner venturi (Fig. 2).

There are two different adjustments to check for in the oven section: pilot safety, and bypass.

1. Pilot Safety Adjustment

With control panel cover removed, light the oven pilot as explained in the oven lighting instructions.

If pilot goes out, increase the pilot safety adjustment until the flame completely engulfs the safety

device sensing bulb. The safety adjustment screw is located on the safety control below the red

button.

2. Bypass Flame Adjustment (Oven and Thermostatically Controlled Griddle)

This adjustment must be made at time of range installation.
