Propane again: the PRG486EDPG belongs to Thermador’s older Pro Grand LP series at 48 inches, and its own installation instructions identify an LP configuration. Thermador’s papers connect it to relatives of three widths (30, 36, 48 inches), including a near twin, the PRL486EDPG-01, so this was a coordinated LP generation and not a single odd unit.
This one is built for propane only, and a gas conversion is not something to attempt in the field. A lighting or flame-quality problem is therefore judged with the supply and regulator in view, not by a natural-gas pattern. Igniters, burner caps, and oven temperature control come next.
If a burner will not light and you smell gas, propane included, close the range’s gas valve before any other step. That priority holds whatever the range’s age or gas type.
On propane, a regulator or supply line problem can weaken every burner at once, so we check it before blaming individual igniters. That is why we always check the supply side first on propane.
Our source describes it as LP-specific and not field-convertible. Ask us before attempting any change. Ask before any conversion attempt, because it can affect safety.
Close the range's gas valve, open windows, avoid flames and switches, and call us once the room is clear. Keep flames and sparks away until the area has cleared.
