To Convert Gas Pressure Regulator
1. Remove the access cap by using a wrench, turning the
access cap counterclockwise.
2. 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.
3. 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 11" (27.9 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 range 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 range 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 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.
6. Replace with correct LP gas orifice spud. See the “LP Gas
Orifice Spud/Hood Chart.”
Use the following chart to find the exact orifice spud
placement.
