Section 7: Fuel Systems; Fuel Cap - THOR Class C Series Owner's Manual

Fuel Systems
Potentially explosive fuel vapor may be present at fuel filling stations and during
refueling of equipment with the fuel transfer system. Never enter a fuel filling station
or refuel equipment if your furnace or water heater is operating or if your refrigerator
is operating on propane. Both the flame and the ignitors in the burners of these
appliances are sources of ignition, and could cause an explosion. These appliances
must be turned OFF before entering a fuel filling station or refueling equipment.
Turning OFF the propane main tank valve only is not sufficient. The appliances must
be OFF at their electrical operating switches.
Fuel-soaked rags or other materials contain flammable and/or explosive fuel vapors
and other hazardous substances. Clean up materials should be temporarily stored in
a nonflammable, vapor-tight container until proper disposal facilities are available.
Do not store flammable clean up rags or materials inside the motorhome, inside any
other vehicle or near any source of flame or ignition.
Be extremely careful when fueling your motorhome. Always shut OFF the engine, do not
smoke, do not use cellular phones, and shut OFF all pilot lights before adding fuel. Fuel spills
represent a serious fire hazard, and should be cleaned up immediately. Never restart the
engine or relight pilot lights while raw fuel is present. When the weather gets cold or your
motorhome has not been used for a while, a fuel additive (customer supplied) may be needed.
Fuel Cap (if so equipped)
If you should lose your fuel cap, it should be replaced as soon as possible, with a cap
of the same type. Always remove the fuel cap slowly and pay close attention to the fuel
recommendations outlined in the Chassis Packet.
