ADJUSTMENTS AND SERVICE WORK MAY BE PERFORMED ONLY BY A QUALIFIED TECHNICIAN WHO IS
EXPERIENCED IN, AND KNOWLEDGEABLE WITH, THE OPERATION OF COMMERCIAL COOKING EQUIPMENT.
HOWEVER, TO ASSURE YOUR CONFIDENCE, CONTACT YOUR AUTHORIZED SERVICE AGENCY FOR RELIABLE

Warranty will be void and the manufacturer is relieved of all liability if service work is performed by other than a qualified

DJUSTMENT OF
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 fitting 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 fitting and replace plug in manifold.
12. Turn on main gas to range and light pilots.
13. Replace control panel.
A
DJUSTMENT OF
The open-top pilots are the non-aerated (yellow-tipped flame) type. One is located beside each open-top burner.
Pilot outage is often caused by an unstable flame due to over-adjustment to the point where the flame 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 flame size is approximately 3/4" (19 mm) with a slight yellow tip. The first 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.
