how many burners do i need?

When it comes to the number of burners of gas hob you need really depends on how you cook, how many people are in your household and how you use your kitchen. For instance, if you just cook a little or you live alone, a gas hob with one or two burners might be just fine. If you have a bigger family you will probably want a gas hob with three or four burners. This way you can cook at the same time and it will make cooking easier.At CHEFF we think about customer' s needs when we decide on the burners. We look at how you cook, what your kitchen is like and how often you will use the gas hob. Our goal is to make sure you can use the burners easily and that they work well. One good thing about CHEFF gas hobs is that the burners are spaced out nicely. This means you can use burners at the same time without the pots and pans getting in the way even if you are using big ones.In addition to functionality, safety is always a top priority in our design concept. Adequate spacing between burners helps reduce heat interference, improves ventilation, and minimizes the risk of accidental contact between cookware and surrounding surfaces. Each configuration is engineered and tested to maintain stable flame performance, efficient heat distribution, and safe operation under simultaneous multi-burner use.Therefore, choosing the right number of burners is not only about capacity, but also about balancing efficiency, kitchen space, and safety. CHEFF is committed to providing tailored solutions that meet different market requirements while ensuring high safety standards, reliable performance, and user-friendly operation for both residential and professional cooking environments.

What happens when I let something boil over?

When a pot boils over in PITT cooking system, we were ready for it. A key aspect of our design is that the windproof burner support ring (the ring you see under your pans) isn’t just there to balance your cookware and boost fuel efficiency by pushing more heat upwards—it works as a built-in catch and spill protector, too!Because of the large burner diameter and smart design, most boiling overs and food splatters won’t travel into the center burner area. Rather, they rest mostly on the heat shield or windproof ring. This keeps debris away from vital gas combustion zones, ensuring continued reliable ignition and consistent flames even after boil-overs.This helps prevent clogs, disrupted gas flow, and uneven flames—all while reducing the potential for grease accumulation inside the burner system.Cleanup is just as easy. In most instances, you simply wipe down the spilled liquid off the outer part of the heat shield itself using a wet cloth or light cleaner. No need for intricate tear-downs which saves time and labor.All in all, CHEFF’s cooking system is engineered for the sake of functionality and security. Even with overflow problems, its design prevents messes from spreading, keeps internal parts secure, and maintains consistent safety — ensuring that you have a stress-free cooking experience whether at home or at your workplace.

How are the burners installed into the countertop?

At CHEFF, we have developed an innovative system for installing our gas burners. Our goal was to create a modular installation concept which enables maximum flexibility when assembling your kitchen project - while ensuring highest safety standards at the same time.All units in our range come assembled on a standardised installation module with predefined gas connection interface. You can install them all the way down from below the countertop using precisely defined cut-outs. In this step-by-step guide, you will learn how exactly to do this.The easiest approach involves fixing the module from above by fastening it to the burners via its heat shield structure. For greater stability, we recommend adding two supporting joist structures. These will be installed into the kitchen cabinets, reinforcing the installation by additionally supporting the underside of the module.We don’t just focus on the installation part at all.

Why it take long time for the safety device to cut off the gas when the flame is out ?

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.

Why the gas hob cannot ignite or it takes a long time to ignite?

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.

What is the lead time for gas hob samples ?

For exsisting models, the sample preparation time is usually about 7 days, because the product structure, materials and production process are mature. That means our engineering and production teams can quickly set up materials, verify specs and move on to sample assembly and testing in a fairly short time frame.For new product developments the sample preparation process normally takes about 21 days. That’s because new models often require more steps like design validation, structural changes, procuring components, building prototypes and testing performance. At this stage all technical details are carefully checked to ensure that the sample meets performance requirements and the expectations of the client before final approval.If mold build up is needed, the overall lead time will be longer, typically 30-45 days. The mold-making process involves design analysis , mold engineering , machining , trial production and a series of optimization steps to ensure precision and durability . The mold has to be tested and approved completely before stable sample production can be started.We have strict quality control and efficient project management in the whole process to make sure on time delivery. We also keep customers updated regularly during sample preparation so they know exactly how things are progressing at each stage. We aim to ensure high accuracy, reliable performance and consistent quality for every sample delivery to support smooth transition to mass production and long term cooperation.
