The PRG486EDPG is an older 48-inch range from Thermador’s Pro Grand series, documented specifically as an LP (propane) gas configuration in its own installation instructions. Thermador’s documentation ties it to a broader Pro Grand LP family spanning 30, 36, and 48-inch sizes, plus a closely related PRL486EDPG-01 sibling, indicating this was a coordinated LP-specific range generation rather than a one-off unit.
Because this range is LP-specific rather than field-convertible in the way some ranges are, any ignition or flame-quality problem should be evaluated with the propane supply and regulator in mind rather than assuming a natural-gas problem pattern. If a burner won’t light and there’s any smell of gas – propane included – shutting off the gas supply to the range comes first, before any other troubleshooting step, and that priority holds regardless of the range’s age or gas type.
