ADJUSTMENT OF GAS PRESSURE REGULATOR

The pressure regulator is factory set at 4” W.C. (0.99 kPa) for natural gas and 10” W.C. (2.48 kPa) for propane gas. To

check the manifold pressure:

1. Turn all thermostats and burner control knobs to OFF position.

2. Turn main gas valve to entire range off.

3. Remove control panel and locate the small plug in the manifold.

4. Remove plug and install a tting appropriate to connect a manometer.

5. Turn on main gas to range and light pilots.

6. Turn all burners and ovens to full ON position and read manometer.

7. If manometer does not read 4” W.C. (0.99 kPa) for natural gas, or 10” W.C. (2.48 kPa) for propane gas, adjust

regulator (if gas pressure is correct go to Step 10).

8. Remove cap from top of regulator.

9. With a screwdriver rotate regulator adjustment screw clockwise to increase, or counterclockwise to decrease, pres

sure until manometer shows correct reading.

10. Repeat steps 1 and 2.

11. Remove manometer tting and replace plug in manifold.

12. Turn on main gas to range and light pilots.

13. Replace control panel.

ADJUSTMENT OF OPEN-TOP PILOTS

The open-top pilots are the non-aerated (yellow-tipped ame) type. One is located beside each open-top burner.

Pilot outage is often caused by an unstable ame due to over-adjustment to the point where the ame is leaving its

port, or “blowing off.” Often, in an effort to improve ignition, the pilots are increased too much and result in this unstable

condition.

The pilots are adjusted by inserting the blade of a screwdriver into the slot on the small valve, located on the manifold.

The maximum ame size is approximately 3/4” (19 mm) with a slight yellow tip. The rst indication of over-adjustment is

evident when the yellow tip begins to stream into black streaks and generate carbon. Continued over-adjustment leads to

the unstable lifting and blowing condition.
