5. 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 gas opening and press down onto the
gas orifice spud and remove by turning the gas orifice spud
counterclockwise and lifting out. Set gas orifice spud aside.
6. 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.

8. Replace the burner base using both screws.
9. Replace burner head and cap.
10. Repeat steps 2 through 9 for the remaining burners.
Complete Installation
1. Refer to the “Make Gas Connection” section for properly
connecting the cooktop to the gas supply.
2. Refer to the “Electronic Ignition System” section for proper
burner ignition, operation, and burner flame adjustments.
IMPORTANT: You may have to adjust the “LO” setting for
each cooktop burner.
Checking for proper cooktop burner flame is very important.
The small inner cone should have a very distinct blue flame
¼" (0.64 cm) to ½" (1.3 cm) long. The outer cone is not as
distinct as the inner cone. LP gas flames have a slightly
yellow tip.
3. Refer to “Complete Installation” in the “Installation
Instructions” section of this manual to complete this
procedure.
Natural Gas Conversion
1. Turn manual shutoff valve to the closed position.
2. Unplug cooktop or disconnect power.
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 “LP” or “NAT” position. Turn over the spring
retainer so the “NAT” 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:
