What is typically the first step in troubleshooting a burner issue?

Verifying gas pressure levels is essential as the first step in troubleshooting a burner issue because gas pressure directly affects the burner's performance. If the gas pressure is too low, the burner may not ignite or operate properly. Conversely, if the gas pressure is too high, it can lead to unsafe operating conditions and inefficient combustion. Ensuring the correct gas pressure will help in identifying whether the problem lies within the gas supply or within the burner itself.

Starting with gas pressure verification gives technicians an accurate baseline to determine if the issue is related to fuel supply, eliminating a common variable that can cause burner problems. This foundational step helps streamline the troubleshooting process, guiding the technician toward more specific repairs if the gas pressure is confirmed to be normal. Other options, such as inspecting for physical damage or adjusting air shutters, may be necessary later, but if the gas pressure is not correct, those steps may not resolve the issue.
