Pre-Installation Checklist:
- Verify that the gas supply is Liquid Propane (LP) and meets local codes.
- Ensure adequate ventilation is available, such as a range hood.

- Unpack all components, including the Propane (LP) Conversion Kit.
Dimensions and Clearance:

Gas Connection:
Connect the rangetop to the LP gas supply line using approved fittings and a flexible gas connector. Ensure all connections are leak-tested before operation.
LP Conversion:
This unit is designed for Liquid Propane. If conversion from natural gas is required (though this model is specified for LP), use the provided LP Conversion Kit and follow the instructions carefully. This procedure should only be performed by a qualified technician.
Operating Instructions
Igniting a Burner:
- Ensure all burner grates are properly seated.
- Push in the desired burner control knob and turn it counter-clockwise to the 'HI' position.
- You will hear a clicking sound as the igniter sparks. Once the burner ignites, continue to hold the knob in for a few seconds to allow the thermocouple to heat up.
- Release the knob. If the burner does not ignite, repeat the process.
- Once ignited, adjust the flame size by rotating the knob between 'HI' and 'LO' settings. The blue LED light will indicate the burner is active.
Using Different Burner Settings:
- HI (High): For rapid boiling, searing, or large volume cooking (up to 18,000 BTU).
- MED (Medium): For general cooking, frying, and sautéing.
- LO (Low): For simmering, melting, and keeping food warm (down to 650 BTU).
Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your rangetop.
Daily Cleaning:
- Porcelain Spill Tray: Wipe down the black porcelain spill tray after each use with a damp cloth and mild detergent. For stubborn stains, a non-abrasive cleaner can be used.
- Stainless Steel Surfaces: Clean stainless steel surfaces with a soft cloth and a stainless steel cleaner. Always wipe in the direction of the grain to prevent streaking.
Periodic Cleaning:
- Cast Iron Grates: The heavy-duty cast iron grates can be removed and washed with warm, soapy water. Dry thoroughly before replacing.
- Burner Caps and Heads: Remove burner caps and heads when cool. Wash with warm, soapy water and a soft brush. Ensure they are completely dry before reassembling to prevent ignition issues.
Caution: Do not use abrasive cleaners, steel wool, or harsh chemicals on any part of the rangetop, as this can damage the finish.
