5. Turn over the gas pressure regulator cap, and reinstall on the
regulator so that the hollow end faces in and the letters
"NAT" are visible.
6. Tighten the gas pressure regulator cap by using a large flat-
blade screwdriver, turning the regulator cap clockwise.
7. 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: 6" (15.2 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 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
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 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 1/2 psi (3.5 kPa).
To Convert Surface Burners from Propane to Natural
Gas
1. If the burner grates are installed, remove them.
2. Remove burner cap.
3. Remove the burner base by first removing (2) T-20 screws.
4. Apply masking tape to the end of a 1/4" (6.4 mm) nut driver
to help hold the gas orifice spud in the nut driver while
changing it. Insert nut driver into the 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.
5. 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.

6. Place Propane gas orifice spuds in plastic parts bag for
future use and keep with package containing literature.
7. Replace the burner base and screws. Tighten screws only
until burner is snug to cooktop, do not over-tighten.
8. Replace burner cap.
9. Repeat steps 2 through 8 for the remaining burners.
