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
The FURNACE is run by PROPANE... The FURNACE BLOWER and control board is run by 12VDC. 12VDC comes from the on-board converter/charger unit when plugged into shore power and is also powered by the 12VDC Battery system...
Here is a simplified diagram showing a 30AMP trailer system wiring..
