ADJUSTMENT OF MANIFOLD GAS PRESSURE
There is not an internal pressure regulator. The external pressure regulators supplied by Blodgett Range 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 fitting 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 fitting and replace plug in manifold.
8. Turn ON all gas valves and light all pilots.
9. Replace valve panel.
