How to Fix / Troubleshooting
Critical safety: If you smell gas, do not operate electrical switches, do not use open flames, and evacuate the area. Shut off the gas supply at the main valve if safe to do so and call the gas supplier or emergency services. For oil smells, place absorbent material under visible leaks and ventilate.
Do not attempt repairs yourself. A licensed technician must locate and repair leaks, test tightness, and verify combustion safety.
