A burner for use with fireplace gas logs includes a burner pan having a gas burner extending across it. A flame control plate is located in the burner pan above the burner. The flame control plate has an opening located in it which is partially covered by a damper. The damper can be moved to cover various portions of the opening which allows directing the burner flame to give the desired effect in the fireplace logs. By installing the burner assembly in a particular manner the fireplace logs can be made to look substantially like real burning logs.
