Prized for their ability to come to temperature quickly, heat food evenly, and recover quickly, gas fryers continue to be commonplace. And when it comes to operating restaurant equipment, perhaps no noise is more ominous than a loud “boom” when you start your gas fryer. This noise, however startling, is not uncommon, but it can be indicative of maintenance work that needs to be done. In this article, we will discuss the some of the likely causes for this sound, whether it’s just an alarming noise or potentially a more serious issue, and will tell you what you should do to ensure the safety of your restaurant, customers, and staff.
Potential Gas Line Issue
A potential reason that your fryer is making that “boom” sound is an issue with the gas line leading to a delayed ignition. A delayed ignition occurs when the gas that your fryer is connected to does not light immediately, and the gas builds up until it touches a flame and finally ignites itself. The result can be a little shocking, and sounds much like a car backfiring.
Delayed ignition can be related to the gas line if there is too little gas at the burners, which prevents the gas from lighting and causes it to build up until there is enough to light. A gas-line issue could also be related to the primary air, which is the air that the gas is mixed with before reaching your fryer. If there is an excess of primary air, it can lead to difficulties with ignition and a subsequent gas buildup. If you suspect a problem with your gas line, it is imperative that you take it seriously.
This is not the sort of thing you want to leave to resolve itself.
Heating Element Malfunction
There could be a potential problem with the heating element of your fryer. Tube fryers, flat-bottomed fryers, and open-pot fryers are all structurally different and heated in a different way, but if the heating element is too near to a source of combustion, that could be the source of your “boom.” This, too, should be dealt with immediately. You also should make sure that no grease has built up in the vents of the fryer, and that all of the vents are properly and regularly cleaned, as many fryer fires that start in restaurants are caused by a simple lack of maintenance. If you find yourself guessing, call in a professional who can assist you in finding the problem part and ordering a replacement from an online OEM supplier like 247restaurantparts.com.
A possible reason for delayed ignition is clogged burners or burner orifices. When gas is prevented from igniting smoothly, it can cause a popping sound when it finally explodes into flame. A clogged burner may be serving as a stopgap between the gas and the flame, preventing the two from connecting efficiently and easily, similar to the gas line issues described above. Be sure to use caution when cleaning the burners, and always check first that the fryer’s gas line is not the problem before you do so.
A “boom” sound when starting your fryer is most likely caused by delayed ignition, which is the disconnect between the gas and the flame that results in a gas buildup and leads to a mini-explosion, improper burner or vent function, or worse. Whichever the case, it is extremely important that you take care of the problem as soon as you hear it.
