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).

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.
