Why is my burner noisy or whistling?

A gentle “whooshing” sound is normal when the unit is in operation. This is a result of the gas moving at very high speeds through the plumbing. When the “whooshing” noise is excessive or is more of a whistle, this may be a sign of a problem. Natural gas installations are more susceptible to noise, based on the physical properties of the gas. As a result of these properties, 2.5 times the amount of gas needs to travel through the plumbing to supply the same amount of heat in the same amount of time as a comparable propane burner. This means that the gas is traveling faster through the plumbing and creating more potential noise. Ensure that there are no kinks or damage to the supplied burner flex-line. Some plumbing components, such as commercially available corrugated stainless steel connectors, can cause excess noise when they are used as part of the gas supply system. Changes to the gas supply should only be made by a licensed gas professional. Contact OGC for more information.
