KitchenAid 30-Inch 4 Burner Gas Rangetop, Commercial-Style Installation Guide

GAS CONVERSIONS

IMPORTANT: Gas conversions from Natural gas to LP gas must 

be done by a qualified installer.

LP Gas Conversion

1.  Turn the manual shut-off valve to the closed position.

2.  Unplug cooktop or disconnect power.

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 

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).

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).

1.  If installed, remove the burner grates.
2.  Remove burner cap.
3.  Remove the burner base.
