To Convert Gas Pressure Regulator
1. Remove the access cap by using a wrench, turning
the access cap counterclockwise.
2. Remove spring retainer from the cap by pushing against
the flat side of the spring retainer. Look at the spring retainer
to locate the "NAT" or "LP" position. Turn over the spring
retainer, so the "LP" is showing on the bottom. Snap the
spring retainer back into the cap. Reinstall the cap onto
the regulator.

3. Test the gas pressure regulator and gas supply line.
The regulator must be checked at a minimum 1" (2.5 cm)
water column above the set pressure. The inlet pressure
to the regulator should be as follows for operation and
checking the regulator setting:
LP Gas:
Minimum pressure 11" (27.9 cm) WCP
Maximum pressure 14" (35.5 cm) WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least
1" water column pressure above the manifold pressure
shown on the model/serial rating plate.
Line pressure testing above ½ psi gauge (14" WCP)
The range and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of ½ psi (3.5 kPa).
Line pressure testing at ½ psi gauge (14" WCP) or lower
The range must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psi (3.5 kPa).

To Convert Surface Burners
1. If the burner grates are installed, remove them.
2. Remove burner cap.
3. Remove the burner base.

4. Apply masking tape to the end of a 7 mm nut driver to help
hold the gas orifice spud in the nut driver while changing it.
Insert nut driver into the gas opening, press down onto the
gas orifice spud, and remove by turning the gas orifice spud
counterclockwise and lifting out. Set gas orifice spud aside.
5. Replace with correct LP gas orifice spud. See the "LP Gas
Orifice Spud/Hood Chart."
Use the following chart to find the exact orifice spud
placement.
Fully insert choke into bottom of medium burner base.
Choke should snap into place.
