Hello, I have a Superior Brand Fireplace and the pilot lights, the flame turns on half way for out 10-15 seconds then goes out. It's a common Superior fireplace issue documented on their site. Looking for someone with experience in this to fix. Electric and gas line both working. Brand: Superior Fireplaces (Lennox Hearth Products) Model: DRI3030TEN Type: Direct Vent Gas Insert Ignition: Electronic ignition system Thanks so much!
