Important Safety Information
This model is specified for natural gas and methane (CH₄) only — not LPG, propane or butane.
This product is not a substitute for correct gas installation, regular appliance servicing or professional safety inspections.
Never ignore the smell of gas simply because the detector has not sounded.
During a suspected gas leak, do not operate electrical switches or create sparks.
Shut off the gas supply only when it is safe to do so.
Ventilate the area and contact the gas supplier or emergency service.
Test the detector regularly according to the manufacturer's instructions.
