The regulator is preset for 4” W.C. for natural gas, or 10” W.C. for propane gas. If adjustment is necessary, do the follow-
ing:
1. Turn cheese melter control knob to OFF.
2. Attach a pressure-measuring device to the 1/8” NPT connector located on the front of each burner manifold.
3. Turn the cheese melter control knob to HIGH and, with the burners lit, check the manifold pressure. The pressure
should be 4” W.C. (for natural gas) or 10” W.C. (for propane gas).
4. If necessary, adjust the pressure by unscrewing the top of the pressure regulator (use a screwdriver) to expose the
adjustment screw underneath. Rotating the adjustment screw clockwise increases the manifold pressure.
5. After the pressure has been adjusted, turn the cheese melter control knob to OFF, replace the top of the pressure
regulator, and disconnect the pressure-measuring device (replacing the plug into the connector on the manifold).
