We have never used the furnace for heat, always take a small space heater and done just fine. But if the TT is hooked to a generator, is the furnace 12v powered or 120 from the genny? Thanks
3 blind mice! You have to have a working converter when hooked to 120. It will run on batteries overnight if you have 2. You can always get up and hook up the 12 V cord to you TV if the battery goes dead.
