My montigo sp28-f2 gas fireplace wall switch is off, gas and pilot light had been shut off and not in used for at least 20 years suddenly making a buzzing noise like a phone ring for a couple of minutes and then stop in the middle of the night for the past two nights. It does not have a battery pack.
