DANGER
Storage batteries give off explosive hydrogen gas during recharging.
Slightest spark will ignite hydrogen and cause explosion.
Battery electrolyte fluid contains acid and is extremely caustic.
Contact with battery contents will cause severe chemical burns.
A battery presents a risk of electrical shock and high short circuit current.
•DO NOT dispose of battery in a fire.
•DO NOT allow any open flame, spark, heat, or lit cigarette during and for several minutes after charging a battery.
•DO NOT open or mutilate the battery.
•Wear protective goggles, rubber apron, and rubber gloves.

Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and without leaks.
Ensure that all gas line shutoff valves are OPEN and that adequate fuel pressure is available whenever automatic operation is desired.
FUEL SYSTEM SELECTION
The engine of your Home Standby Generator is factory calibrated to run on natural gas (NG). It may also be operated on liquefied petroleum (LP).There is no additional hardware/equipment required to switch between either fuel. However, LP fuel inlet pressure must be between
11 and 14 inches water column.
To configure the fuel system for LP use:
•Set the AUTO/OFF/MANUAL switch to OFF.
•Remove the 15 Amp fuse.
•Connect the fuel transfer solenoid as follows:
1.Remove the “Oil Service” access door.
2.Join the
