The appliance's approved fuel configuration matters to its components and safe operation. A shared model appearance does not establish that one version suits another gas supply.
What the observation means
Conversion is specialist work and is outside this service's stated scope. A previous owner's claim is not a substitute for the correct appliance identification and records.
A useful next step
Provide the existing fuel information when making an enquiry and obtain appropriate qualified advice if it is uncertain. Do not fit jets or alter regulators based on an online chart. Any smell of gas takes priority over ordinary fault finding.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
