Instruction Sheet

4
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
1
/
2
psi gauge (14" 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 gauge (14" 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).
5. If the burner grates are installed, remove them.
Use the following charts 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 W10686630 or Natural gas with Natural
gas High Altitude Kit Part Number W10686629. 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 through 3 of the necessary conversion.
