To Convert Gas Pressure Regulator
1.
Remove the access cap by using a wrench, turning the
access cap counterclockwise.
Remove spring retainer from the cap by pushing against the
flat side of the spring retainer. Look at the spring retainer to
locate the “LP” or “NAT” position. Turn over the spring
retainer so the “NAT” is showing on the bottom. Snap the
spring retainer back into the cap. Reinstall the cap onto the
regulator.
2.
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:
Natural Gas:
Minimum pressure 5" (12.7 cm) W.C.P.
Maximum pressure 7" to 14" (17.8 cm to 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 they are installed, remove the burner grates.
Use the following figures to match the correct Natural gas
orifice spud with the burner location and model being
converted. The orifice spud size is stamped on the orifice
spud as shown below. This number codes the orifice
diameter and its correct burner location.

3.
For the right front burner only, remove the aluminum choke
from the burner orifice holder.
