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

psi gauge (14" 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

psi (3.5 kPa).

Line pressure testing at

psi gauge (14" 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

psi (3.5 kPa).

To Convert Surface Burners

1. If the burner grates are installed, remove them.

2. Remove burner cap.

3. Remove the burner base.

burner, LP gas only)

Small Burner

A. Burner cap

B. Burner base

4. 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, 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 LP gas oriﬁce spud. See the “LP Gas

Oriﬁce Spud/Hood Chart.”

Use the following chart to ﬁnd the exact oriﬁce spud

placement.

Fully insert choke into bottom of medium burner base.

Choke should snap into place.
