I could really use some help to get my fireplace lit without power. It's a heat and glo unit with an intermittent pilot ignition (IPI) igniter with no manual igniter switch. I've put two D cell batteries in the battery pack under the fireplace and confirmed the batteries are good. Go to flip the switch on the fireplace and no ignition. I think it's because the fireplace switch is on a three way switch. During normal operation I have to flip a switch on my living room wall, then flip the switch on the side of the fireplace. Is that why the battery pack is not working to start the fire, because the circuit isn't closing with the three way switch? Power came on last night and the fireplace started up without issue, but when power went back off this morning the fire cut out. I'm at a loss and really need to get the fire working to at least heat up part of the house.
