COOKTOP SAFETY
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.” These words mean:
DANGER
WARNING
You can be killed or seriously injured if you don't immediately follow instructions.
You can be killed or seriously injured if you don't follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed.
WARNING: If the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury or death.
–Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
–WHAT TO DO IF YOU SMELL GAS:
•Do not try to light any appliance.
•Do not touch any electrical switch.
•Do not use any phone in your building.
•Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
•If you cannot reach your gas supplier, call the fire department.
–Installation and service must be performed by a qualified installer, service agency or the gas supplier.
WARNING: Gas leaks cannot always be detected by smell.
Gas suppliers recommend that you use a gas detector approved by UL or CSA.
For more information, contact your gas supplier.
If a gas leak is detected, follow the “What to do if you smell gas” instructions.
In the State of Massachusetts, the following installation instructions apply:
■Installations and repairs must be performed by a qualified or licensed contractor, plumber, or gasfitter qualified or licensed by the State of Massachusetts.
■If using a ball valve, it shall be a T-handle type.
■A flexible gas connector, when used, must not exceed 3 feet.

Tools and Parts
Gather the required tools and parts necessary for correct LP gas conversion.
Tools needed
■Flat-blade screwdriver
■³⁄" (#0 [2.0 mm]) flat-blade screwdriver (screwdriver shaft must be a minimum of 2" [5.1 cm] long)
■Adjustable wrench
■7.0 mm nut driver
■7.0 mm wrench
■T10 Torx®† adapter
Parts needed
For models KCGS550ESS, KCGS556ESS, KCGS950ESS and KCGS956ESS use the following parts:
■LP orifice package (W10676662)
■Conversion instructions (W10597146A) For all other models use the following parts:
■LP orifice package (W10676661)
■Conversion instructions (W10597146A)
High Altitude Conversion
To convert the cooktop for elevations above 6,560 ft (1999.5 m), order a High Altitude Conversion Kit.
For models KCGS550ESS, KCGS556ESS, KCGS950ESS and KCGS956ESS use the following parts:
■Part Number W10679116 - LP high altitude
■Part Number W10679118 - Natural gas high altitude For all other models use the following parts:
■Part Number W10679114 - LP high altitude
■Part Number W10679113 - Natural gas high altitude
To order, see the “Assistance or Service” section of the User Guide.
IMPORTANT: Gas conversions from Natural gas to LP gas must be done by a qualified installer. Before proceeding with conversion, shut off the gas supply to the cooktop prior to disconnecting the electrical power.
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.

WARNING
Use a new CSA |
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.

3.Determine the type of regulator you have:
Style 1: The cap has a slot and “NAT” printed on it.
Remove access cap by using a flat-blade screwdriver or coin, turning the access cap counterclockwise.
3
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
½psi (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.
