Natural Gas:
Minimum pressure: 6" (15.2 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 cooktop and its individual shutoff 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 cooktop must be isolated from the gas supply piping
system by closing its individual manual shutoff 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 installed, remove the burner grates.
2. Remove burner cap.
3. Remove the burner head.
NOTE: A
⁷⁄₈
" socket must be used to remove the burner head
of the large dual burners.
4. Using a T15 Torx
®
screwdriver, remove the burner base.
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 Natural gas orifice spud. See the
“Natural Gas Orifice Spud/Hood Chart.”
Use the following chart to find the exact orifice spud
placement.

7. Place LP gas orifice spuds in plastic parts bag for future use
and keep with package containing literature.
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.
