LP Gas Conversion Instructions
4
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 turning it
counterclockwise. 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. Screw the spring retainer
back into the cap, turning it clockwise. 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 10" (25.4 cm) W.C.P.
Supply pressure 14" (35.5 cm) W.C.P.
Gas Supply Pressure Testing
Line pressure testing above ½ psi gauge (14" WCP)
The cooktop 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 cooktop 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.
Use the following charts to match the correct gas orifice spud
with the burner location and model being converted.

2. Remove burner cap.
3. Remove the burner base.
NOTE: Remove one burner base at a time. Then replace after
converting. Do not disassemble entire cooktop.
