Why This Matters
Natural gas and LP operate at different pressures and have different energy densities. Using LP gas through a natural-gas orifice produces flames that are far too large and can exceed the burner ring, creating a fire hazard. Conversely, using a natural gas orifice with LP results in an insufficient flame. Either scenario is unsafe and can damage the appliance.
Inspection Points Before Conversion
- Confirm you have the correct DCS LP conversion kit for your specific rangetop model number
- Verify that all orifices in the kit match the burner BTU ratings listed in the owner’s manual
- Check that the LP supply pressure at the regulator is within the range specified in the manual (typically 10–11 inches W.C.)
- Ensure the conversion is being performed by a licensed gas technician or plumber
- Confirm the conversion decal will be affixed to the appliance after completion
Recommended Action Steps
- Purchase only the official DCS LP conversion kit for your rangetop model — do not substitute third-party orifices.
- Shut off the LP supply at the tank and confirm pressure has dissipated before opening any gas fittings.
- Replace all burner orifices, including the oven and broiler orifices if applicable, not just the surface burners.
- Adjust the low-flame bypass screw on each valve per the conversion instructions to prevent flame-out at low settings.
- After reassembly, pressure-test all connections with a soap solution before restoring gas supply.
- Light each burner and verify a stable, cone-shaped blue flame at low, medium, and high settings.
- Complete and retain all conversion documentation; attach the LP conversion label to the appliance in the location specified by DCS.
When to Call a Technician
LP conversion must be performed by a licensed gas professional in most jurisdictions — it is not a homeowner DIY task. If you have any doubt about the conversion or notice abnormal flame appearance after conversion, contact DCS Customer Support before further use of the appliance.

This notice covers dcs rangetop lp conversion safety guide. Read the full advisory below for affected models, safety actions, and next steps.
DCS rangetop LP conversion safety requirements must be followed precisely when switching a natural-gas-configured rangetop to liquid propane (LP) operation, because an incorrect conversion can result in unsafe flame behavior, gas leakage, and voided warranty coverage.
DCS CPU-366 and CPU-486 rangetops ship configured for natural gas at the factory. Converting to LP requires replacing the burner orifices with the LP-specific orifice set included in the DCS LP conversion kit, adjusting the low-flame bypass screw on each valve, and verifying the supply pressure with a manometer. This advisory outlines the safety requirements for that process.
