REGULATOR INSTALLED IN A HORIZONTAL, UPRIGHT POSITION
The RRG series units must have an exterior machine gas regulator installed. The units are shipped with a regulator that has a vent limiter. These regulators must be installed as close as possible to the unit in a horizontal, upright position for optimal
performance. They are adjusted by removing the adjustment cover – then by turning the adjustment screw clockwise to increase and counter clockwise to decrease. The regulator and griddle can be damaged by gas pressures that exceed 14” W.C. or ½ psig.

REGULATOR TROUBLESHOOTING
SYMPTOM – UNIT WILL NOT MAINTAIN CONSISTENT PRESSURE
1.Check that vent limiter is not clogged by grease and debris
2.Check store gas pressure before regulator with all equipment on that line turned on and consuming gas
A.For natural gas should be between 7” and 14” W.C.
B.For propane gas should be between 12” and 14” W.C.
3.Check that regulator is installed in a horizontal, upright position
4.If no problems found in steps 1 – 3, replace the regulator
GAS PRESSURE MEASURMENT
1.Set the power on/off switch to the OFF position.
2.Turn the gas supply off at a manual shutoff valve.
3.Remove the control panel.
4.Remove the pressure tap plug from the far left/#1 burner port and attach manometer
5.Turn gas back on and turn power switch to the ON position
6.Turn all thermostats on to the maximum setting so that all burners are on.
7.Turn all the equipment on the same supply line on.
8.Check gas pressure
9.Gas pressure should read 5” W.C. for natural and 10” W.C. for propane gas.
10.Turn off the power switch.
11.Turn gas supply off, disconnect manometer and reinstall pressure tap plug.
