New 17+ Heat N Glo Fireplace Pilot Light On But Won't Start
New 17+ Heat N Glo Fireplace Pilot Light On But Won't Start. Heat & glo® gas fireplace troubleshooting video. Has the pilot light on your heat & glo fireplace gone out? I took the cover off the fireplace, and manually flipped the switch. If the pilot stays on but the flame goes out under the logs, change your thermopile and look for a bad connection at the gas valve or switch.
