without the optional Onan LP Generator running. The house
battery bank provides 12-Volt electrical power to the furnace
unit and the fan. It will operate as long as a sufficient charge
remains in the battery bank. It will also operate with the
Mercedes-Benz 3.0 turbo diesel running, as long as the
coach has a sufficient fuel supply.
