JacketWater Heater and Internal Battery (OPTIONAL)
This generator can be equipped as an option with a jacket water heater and an internal battery charger. They are provided with electric cords to connect to a commercial power source.
These units will ONLY function when commercial power has been supplied to them (Figure 57). When using extension cords, refer to Table 6 for the correct size and length.
The battery charger should always be connected to a commercial power source to ensure that the battery does not get discharged.
When using the generator in hot climates there is no need to apply power to jacket water heater. However, if the generator will be used in cold climates, it is best to apply power to the jacket water heater at all times.
