Conversion to LP or Natural Gas operation should be performed by a qualified technician or installer.

Installation Instructions
Gas Conversion and Low Flame Adjustment
Converting the Regulator:
After you have installed the appropriate orifice, the regulator must be set for the appropriate gas also. With the control
panel off, locate the gas pressure adjustment cap. See Fig. K Page 13). Remove the cap, turn it over and reinstall the cap. The cap has one side
marked Nat Gas and the other side marked as LP Gas (see
Fig.
N ).
Checking the Pressure:
The gas pressure must be checked after the conversion. The grill must be installed with the gas and electrical connections.
See page 5 of the manual. Remove the pressure tap screw (
Fig.
O). Attach a manometer or pressure gauge to the pressure tap hole. Turn the valve
knob to the “ON” position.
The unit must be turned on to check the pressure.
The gas pressure for Nat gas is 3.5” WC. For LP gas the pressure
is 10”WC. Minimum input pressure for Nat. gas is 3.5” WC, for LP gas 10” WC. Maximum gas inlet pressure for Nat & LP gas is 13” WC.
WARNING:
The gas must be turned off immediately after checking the pressure and the pressure tap screw replaced and checked for leaks. Seri-
ous injury, property damage or death may occur if gas is allowed to escape from pressure tap.
Adjusting the Valve:
After a gas conversion from LP to Nat or Nat to LP, it may be necessary to adjust the valve because of too low or too high
flame on the low setting. In some cases the flame height may be adjusted to compensate for varying gas pressures. First light the grill following the
directions on page 11 of the manual. Then turn the valve knob to the “Low” setting and remove the knob. This will expose the valve stem. Look
inside the valve stem and you will see a low flame adjustment screw. With the grill burning, turn the screw counter clockwise to make the low
flame bigger. Turn the screw clockwise to decrease the flame size. See (Fig P below).
Warning:
Do not remove the screw, Leaks will occur.
If
there is a leak, turn the screw clockwise until leak subsides. After you are satisfied with the flame height, replace the knob and turn the unit off.

TURN OFF GAS AND ELECTRIC SUPPLY. Before you begin, turn off the gas supply at the shut-off valve.
Disconnect the electrical supply from the grill.
Failure to make the appropriate conversion can result in serious personal injury and property damage.
1. Locate the regulator that is attached to the inlet on the grill and remove the vent cap. Turn the insert over and then reinsert the
opposite side into the regulator.
