Natural Gas Conversion
1. Turn the manual shut-off valve to the closed position.
2. Unplug cooktop or disconnect power.
To Convert Gas Pressure Regulator
1. Remove the gas pressure regulator cap by using a
large at-blade screwdriver, turning the regulator cap
counterclockwise. When the cap is removed, do not lose the
metal seal.
2. Remove spring retainer from the cap by turning the spring
retainer counterclockwise. Locate the “LP” and “NAT”
position on the spring retainer. Turn over the spring retainer
so the “NAT” arrow is pointing toward the cap.
3. Tighten the gas pressure regulator cap by using a large
at-blade screwdriver, turning the regulator cap clockwise.
4. 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:
Natural Gas:
Minimum pressure: 5" (12.7 cm) WCP
Maximum pressure: 14" (35.6 cm) WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least 1"
(2.5 cm) water column pressure above the manifold pressure
shown on the model/serial/rating plate.
Line pressure testing above 1/2 psi (3.5 kPa) gauge (14"
[35.6cm] WCP)
The cooktop 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 1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi (3.5 kPa) gauge (14"
[35.6cm]WCP) or lower
The cooktop 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 1/2 psi (3.5 kPa).
To Convert Surface Burners
1. If installed, remove the burner grates.
2. Remove burner cap.
3. Remove the burner base.

4. Apply masking tape to the end of a 1/4" (7 mm) nut driver
to help hold the gas orice spud in the nut driver while
changing it. Insert nut driver into gas opening and press
down onto the gas orice spud and remove by turning the
gas orice spud counterclockwise and lifting out. Set gas
orice spud aside.
5. Replace with correct Natural gas orice spud. See the
“Natural Gas Orice Spud/Hood Chart.”
