Gas Pressures
The griddle requires the proper gas pressure setting to operate properly. All pressure readings
should be taken after the unit has reached a temperature of at least 200°F and while it is running
to ensure proper flow rates.
Required Material: • Manometer
• 1/8” NPT barbed hose fitting
• 1/4" NPT barbed hose fitting
• Two 2-inch long lengths of approximately 1/8” diameter flexible rubber
hose (closed on one end)
Tasks:
1) Verify pressure regulator vents are clear before making any pressure adjustments.
2) Remove the 1/8” NPT pipe plug from the main gas valve and install the 1/8” NPT barbed hose
fitting. Tighten and mount one length of the rubber hose.
3) Remove the ¼” NPT pipe plug from the downstream fitting after the pilot burner pressure
regulator and install ¼” NPT barbed hose fitting. Tighten and mount the other length of the
rubber hose.
4) Allow the griddle to heat up to at least 200°F. First, check the main burner regulator pressure.
Remove the rubber hose and replace with the manometer tube. The pressure should be 5”
WC for natural gas and 10“ WC for propane (Caution: Pressure must be set with the main
burners on.) If the pressure does not meet or exceed these values, remove the cap on the
main burner pressure regulator and adjust it to the necessary value.
5) Check the pilot burner pressure (pilot burner regulator) in the same manner as the main burner
pressure. The pressure should measure 3.5” WC for natural gas and 8” WC for propane. If
the pressure does not meet or exceed these values, remove the cap on the pilot burner
pressure regulator and adjust it to the necessary value.
6) Replace the hose fittings with original pipe plugs.
