About the Products

Poor quality safety device is one of the primary reasons that the gas supply may take a long time to shut off after the flame has gone out. A gas hob uses a safety device, or flame failure device (FFD), which automatically shuts off the flow of gas if there is no flame. Unfortunately, if a manufacturer uses low-quality components in this device, it can severely affect the entire safety system's performance.In many instances, the delay in shutting down occurs from the inability of the solenoid valve within the safety system to respond correctly. When either the internal solenoid valve spring does not return to its original position quickly enough or the electromagnet coil gets too weak, unstable, or possibly burnt, the valve will not close almost instantaneously upon the flame's extinguishment causing the supply of gas to continue flowing longer than usual thus creating an unsafe condition.Quite often, the poor quality of the materials used, combined with incorrect assembly and lack of adequate quality assurance testing of the unit may compound the delay problem.At CHEFF, we emphasize the safety of every gas hob we make. All safety devices in our products are high quality parts that are selected to manufacturers' specifications and meet strict international safety standards. We only work with reputable suppliers as well as carrying out careful inspections and testing prior to production and assembly to ensure that each component will work reliably and responsively.This stringent quality assurance process allows us to produce some of the fastest flame failure devices in the industry, cutting-off ignition gas flow in 5–15 seconds after the flame has gone out. This is a much faster response time than what is generally acceptable in the marketplace and provides a much more secure and reliable environment for consumers. This rapid means of cutting gas flow will minimize the risk of gas leaks and will greatly increase the overall safety of your kitchen.In addition to our focus on safety, our engineering team works tirelessly to continuously improve the overall design and functionality of our safety system through rigorous testing, obtaining user feedback, and making necessary modifications. Each product manufactured is subjected to multiple safety tests prior to leaving the factory to ensure that your safety will be consistent across various conditions of equipment usage.

There are several common reasons why a gas hob cannot ignite or takes a long time to ignite. Proper troubleshooting should be carried out step by step to identify the root cause and ensure safe and efficient operation.(1) No gas supply or low gas flowIf your gas hob will not ignite at all, the first and most basic check is to ensure that you have an adequate gas supply. Make sure that the gas cylinder valve is fully opened and there is enough gas in the cylinder. Also, ensure that the gas regulator is functioning well. You should also check the flexible gas hose for any bending, twisting, crushing or blockage as any obstruction in the gas pathway will prevent gas from reaching the burner. Proper ignition requires a steady and continuous flow of gas.(2) Spark electrode damaged, dirty, or incorrectly positionedThe ignition spark is generated by one of the main parts called the spark electrode. If it is damaged, contaminated with grease or food residue, or is out of proper position, ignition performance will be affected or delayed. During normal operation the spark electrode should produce a strong, consistent spark which will readily ignite the gas/air mixture. If the electrode surface is dirty, it should be carefully cleaned to remove any carbon deposits or oil build-up. If not aligned, position it so that the distance between the spark pin and burner flame hole is about 3.5-5mm. If the gap is too large or small, the ignition may be weak, unstable or may not even occur.(3) Other possible factorsIn addition to the above two main reasons, ignition problems can also happen due to low battery power in battery operated ignition systems, moisture in the burner area or clogged burner ports. Blocked burner holes can lead to incorrect gas flow and mixing, causing delayed or uneven ignition. It is recommended that the burner head be cleaned and maintained regularly for best performance.At CHEFF, we are committed to stable and reliable ignition performance for all of our gas hob products. Each ignition system is thoroughly tested prior to shipping to ensure fast and consistent sparking. The design allows for efficient mixing of gas and air and for correct placement of electrodes to ensure easy ignition in normal operation.If a gas hob is installed properly, used properly and maintained properly it should ignite quickly and safely. If you still have the problem after checking the above factors, we recommend you to contact technical support for further check and professional help.

CHEFF gas hobs use an ignition valve that is designed to last and to perform reliably even under frequent use. Our ignition valves can be used for more than 50,000 ignition cycles under normal operating conditions, which guarantees reliability and consistent performance during the product’s service life.This high durability is achieved by using high quality materials, precision engineering and strict manufacturing standards. Ignition valve Each ignition valve is made of selected components resistant to wear, heat and electrical fatigue, so that it can maintain stable ignition performance even after long use. Furthermore, its internal structure is optimized to reduce mechanical stress during repeated operation, thus increasing its working life.All ignition valves are tested and under strict quality control before shipment to assure reliability of the product. We simulate long term use conditions and conduct repeated ignition cycle tests to validate stability, safety and consistency. We only approve products for customer delivery that fully meet our internal standards.The actual service life in practical applications depends on the frequency of use, installation environment, gas quality and maintenance habits. But for normal household or commercial use our ignition system is designed to last for years of stable operation without failing.At CHEFF, we are committed to providing safe, durable and high performance gas hob components. Our commitment to quality control and engineering excellence guarantees every ignition valve delivers reliable ignition, enhanced safety and long service life, enabling customers to reduce maintenance costs and increase end-user satisfaction.
