ADJUSTMENTS
ADJUSTMENT OF MANIFOLD GAS PRESSURE (OVEN BASE)
There is not an internal pressure regulator. The external pressure regulators supplied by Southbend are factory set at
6” W.C. for natural gas and 10” W.C. for propane gas. To check the manifold pressure, do the following:
1. Turn OFF all thermostats, burner controls, gas shut-off valves, and the external gas supply connection(s).
2. Remove the valve panel and locate the 1/8” plug in the front manifold furthest from the gas connection location.
Remove the plug and install a tting appropriate to connect a manometer.
3. Turn ON all gas supply valves and light all pilots.
4. Turn all burners and ovens to full ON position and read manometer.
5. If manometer does not read 6” W.C. for natural gas (or 10” W.C. for propane gas) adjust regulator by removing
the cap from the top of regulator. Use a screwdriver to rotate the regulator adjustment screw clockwise to increase
pressure, or counterclockwise to decrease pressure, until manometer shows correct reading.
6. Turn OFF all thermostats, burner controls, gas shut-off valves, and the external gas supply connection(s).
7. Remove manometer tting and replace plug in manifold.
8. Turn ON all gas valves and light all pilots.
9. Replace valve panel.
ADJUSTMENT OF MANIFOLD GAS PRESSURE (BROILER)
ADJUSTMENT OF PRESSURE REGULATOR
The pressure regulator is factory set at 4” W.C. for natural gas and 10” W.C. for propane gas. To check and/or adjust the
pressure, do the following:
1. Locate the pressure regulator and 1/8” pressure tap, which are located in the service compartment at the bottom of
the broiler (which is accessed through a removable panel on the front of the broiler, see Figure 4). The tap is located
just after the pressure regulator. A manual gas shut-off valve is located just before the pressure regulator.
2. Turn all burner control valves to the OFF position, then turn the manual gas shut-off valve to the OFF position.
3. Remove the 1/8” plug from the pressure tap and connect the manometer.
4. Turn the manual gas shut-off valve to the ON position.
5. Light the pilots.
6. Turn all burner control knobs to the HIGH position. Verify that the burners ignite.
7. Check whether the manometer reads 4” W.C. for natural gas (or 10” W.C. for propane gas). If it does, skip to Step
11, otherwise continue with the next step.
8. Remove the cap from the top of the pressure regulator.
9. Using a screwdriver, turn the regulator adjustment screw clockwise to increase, or counterclockwise to decrease,
the pressure until the manometer shows the correct pressure.
10. Put the cap back on top of the pressure regulator.
11. Turn all burner control valves to the OFF position, then turn the manual gas shut-off valve to the OFF position.
12. Disconnect the manometer and replace the 1/8” plug into the pressure tap.
13. Replace the removable lter on the front of the broiler.
14. Turn the manual gas shut-off valve to the ON position.
15. Light the pilots.
16. Turn on the broiler burners and check for normal ame appearance.
