3. Determine the type of regulator you have:
Style 1: The cap has a slot and “NAT” printed on it.
Remove access cap by using a flat-blade screwdriver or coin,
turning the access cap counterclockwise.
The gas pressure regulator has 2 settings that are stamped
on either side of the cap. Turn the cap and reinstall into
regulator with the stamp “LP” visible from the outside of the
regulator.
Style 2: The cap does not have a slot and requires a wrench
to be removed.
Remove the access cap by using a wrench, turning the
access cap counterclockwise.
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.
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:
LP Gas:
Minimum pressure 10" (25.4 cm) W.C.P.
Supply pressure 14" (35.5 cm) W.C.P.
Gas Supply Pressure Testing
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).
5. If they are installed, remove the burner grates.
Use the following chart to match the correct gas orifice spud with
the burner location and model being converted.

High Altitude Conversions
IMPORTANT: You must convert LP gas with LP gas High Altitude
Kit Part Number W10593220 or Natural gas with Natural gas High
Altitude Kit Part Number W10593221. If you need to convert LP
gas to Natural gas high altitude or Natural gas to LP gas high
altitude, you must convert the pressure regulator. For this, follow
steps 1-3 of the necessary conversion.
LP Gas Orifice Spud Chart for High Altitude Conversion
See chart in the “LP Gas High Altitude Conversion Kit.”
