2020 Jayco GrayHawk 12 Cu.Ft. Double door Refer Gas Flash???

Hi all. New 2020 Class'C' with 12 CuFt. double wide refrigerator gives a very short but scary noise when it ignites on Gas mode? Its as if the gas in the outside chimney is excess and when the spark happens it gives the noise? I've used it for 2 months and its always done it. Can't really locate where this noise is happening.???:E
