CAUTION:
Before proceeding with the conversion, shut off gas supply to the appliance prior
to disconnecting the electrical power.
WARNING
This conversion kit must be installed by a qualified service agency in accordance with the
manufacturer’s instructions. All applicable codes and requirements of the authority
having jurisdiction must be followed. If the information in these instructions is not
followed exactly, fire, explosion or production of carbon monoxide may result, causing
property damage, personal injury or loss of life. The qualified service agency is
responsible for the proper installation of this kit. The installation is not proper and
complete until the operation of the converted appliance is checked as specified in the
manufacturer’s instructions supplied with the kit.
STEP 1
GAS SUPPLY
Measure the incoming gas pressure to the regulator.
With the installation of this conversion kit, the range should operate on LP gas at 10" of water column pressure
and on natural gas at 5" of water column pressure.
The pressure regulator must be connected in series with the manifold of the range and must remain in
series with the supply line.
When checking the regulator, the inlet pressure must be at least 1" greater than the regulator output
setting.
– If the regulator is set for 10" of water column pressure, the inlet pressure must be at least 11".
For proper operation, the maximum inlet pressure to the regulator must be no more than 14" of water column
pressure for LP gas and 9" water column pressure for natural gas.

IMPORTANT:
Disconnect the range and the individual shut-off valve from the gas supply piping system
during any pressure testing of that system at test pressures greater than 1/2 psig. Isolate
the range from the gas supply piping system by closing the individual manual shut-off
valve to the range during any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig.
STEP 2
REPLACE COOKTOP BURNER ORIFICES AND VALVE BYPASS JETS
To replace cooktop burner orifices:
1. Remove the grates from the cooktop.
2. Remove burner caps and brass port rings (refer to diagram below).
3. Unscrew the brass nuts using a 1-1/16” socket or adjustable wrench and lift the simmer rings from the

STEP 6
RE-ASSEMBLE SURFACE BURNERS, CHECK OPERATION
Cooktop Section
Re-assemble the burners and valve panel in the reverse order shown in Step 2 above. Make sure the brass port
rings are properly engaged in the simmer rings.
Check for proper ignition:
Connect electrical power.
Push in one control knob and turn 90° to “HI” position.
The igniter will spark and the burner will light; the igniter will cease sparking when the burner is lit. (Note
that all burners will spark.)
The first test may require some time while air is flushed out of the gas line.
Turn knob to “OFF”.
Repeat the procedure for each burner.
Check Flame Quality
Check for proper burner flame characteristics (see diagram).
Burner flames should be blue and stable. Some yellow tipping may be normal on LP Gas. The flame should not
have excessive noise or exhibit lifting of the flame from the burner. Due to differences in gas characteristics and
burner usage (i.e. gas pressure, cleanliness, etc.), burners may perform differently.
Burner Operation
Two flames are used on all five burners.These dual flame burners have an upper ring of main burner ports that
produce the main flame for high heat cooking from the “HI” knob setting to the “LO”knob setting.
The bottom simmer flame is used for simmer heat cooking operations such as melting chocolate, holding food at
serving temperature and simmering. Both flames are lit when the knob is between “HI”and “LO”.Only the simmer
flame is lit when the knob is in the “SIM” position.
Burner Adjustment
There is no air shutter adjustment, etc. on this burner.
The only adjustment available is to clean the burners and clean or replace orifices.
