happen if the instructions are not followed.
Your safety and the safety of others are very important.
We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety
messages.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING.”

WARNING
This conversion kit shall be installed by a
qualified service agency in accordance
with the manufacturer's instructions and
all applicable codes and requirements of
the authority having jurisdiction. If the
information in these instructions is not
followed exactly, a 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
this kit.
A. To cooktop
B. Shutoff valve (closed position)
C. Gas supply line

B. Rear of cooktop
C. Gas pressure regulator
D. Gas flow
WARNING
Explosion Hazard
Use a new CSA International approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified person make sure
gas pressure does not exceed 14" (36 cm) water
column.
Examples of a qualified person include:
licensed heating personnel,
authorized gas company personnel, and
authorized service personnel.
Failure to do so can result in death, explosion, or fire.

The gas pressure regulator has 2 settings that are stamped
on either side of the cap. Turn the cap and reinstall into
regulator with the stamp “LP” visible from the outside of the
regulator.
Style 2: The cap does not have a slot and requires a wrench
to be removed.
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 “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.
4. 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).
5. If the burner grates are installed, remove them.
Use the following charts to match the correct gas orifice spud
with the burner location and model being converted.

Lighting the Electronic Igniters
The cooktop burners use electronic igniters in place of standing
pilots. When the cooktop control knob is pushed in, the system
creates a spark to light the burner. This sparking continues until
the control knob is turned to the desired setting.
To Check Operation of the Cooktop Burners:
1. Push in and turn knobs to the ignition position (see the User
Guide for additional information). The cooktop burner flame
should light within 4 seconds. The first time a burner is lit, it
may take longer than 4 seconds to light because of air in the
gas line. Do not leave the knob in the ignition position after
the burner lights.
2. If burners do not light properly, turn the control knob to the
Off position. Make sure the burner caps are in the proper
position.
3. Check that the power supply cord is plugged in. Check that
the circuit breaker has not tripped or the household fuse has
not blown.
4. Check that the shutoff valve is in the open position.
5. Check burner operation again.
If one or all of the burners do not light at this point, see
“Assistance or Service” section in the User Guide.
Flame Height Adjustment
Each burner flame has been factory set to the lowest position
available to provide reliable and constant reignition of the burner.
However, each burner can be adjusted.
NOTE: If your model number begins with KGCS5 or KGCS9, call
service, as this operation will require opening the unit.
To Adjust:
The flame can be adjusted using the adjustment screws
underneath the control knob.
NOTE: Check the Use and Care Guide for information on each
burner to determine whether they are single or dual flame. Adjust
the valves accordingly.
Adjustment for Single Valve
1. Set the burner flame to LO.
2. Remove the control knob.
3. Hold knob stem with a pair of pliers. Use a ³⁄₃₂" (#0 [2.0 mm])
flat-blade screwdriver to turn the screw located within the
shaft of the control knob stem until the flame is the proper
size.
4. For LP gas conversion:
Completely tighten screw “C” to set the minimum flame
height.
For Natural gas conversion:
Tighten screw “C” to reduce flame height. Loosen screw to
increase flame height. See “Complete Burner Adjustment”
section.
5. Replace the control knob.
6. Test the flame by turning the control from LO to HI, checking
the flame at each setting.
Adjustment for Dual Valve
To Adjust Inner Crown Flame:
1. Set the inner crown flame to LO.
2. Remove the control knob.
3. Remove the black rubber grommet.
4. Using needle-nose pliers, remove the gray shield inside the
burner valve opening.

6. Replace the control knob.
To Adjust Outer Crown Flame:
1. Set the outer crown flame to LO.
2. Remove the control knob.
3. For LP gas conversion:
Completely tighten screw “B” to set the minimum flame
height.
For Natural gas conversion:
Tighten screw “B” to reduce flame height. Loosen screw to

section.
4. Replace the gray shield. Use a screwdriver to help push the
shield into place.
5. Replace the black rubber grommet.
6. Replace the control knob.
7. Test the flame by turning the control from LO to HI, checking
the flame at each setting.
Complete Burner Adjustment
1. Check burner flame(s) for a proper size and shape. The
cooktop low burner flame should be a steady blue flame
approximately ¹⁄₄" (0.64 cm) high.
2. Completely fill out the conversion label and attach label to
bottom of the cooktop next to the rating tag. Do not cover the
rating tag with the conversion label.
IMPORTANT: Place gas orifice spuds in plastic parts bag for
future use and keep with package containing literature.
