The generator and heating and hot water system are fueled from a line installed above the quarter tank level of the gasoline tank preventing them from causing the tank to be depleted.
If the gasoline falls below the 1/4 full level, the generator will not receive fuel and will not start.
The Timberline Heating & Hot Water system will use its internal electric element to operate if the touring coach is connected to shore power.
To keep all systems operating effectively, it's always recommended to keep your gasoline tank as full as possible.
