in Section 3, Vehicle Safety, and safety labels affixed to your
motorhome.
Strictly adhere to all propane safety warnings and operational
guidelines printed on propane appliances, devices, and included
in propane appliance manufacturer’s operational manuals.
Always be mindful that propane gas can be hazardous if used
improperly. Propane is heavier than air, and if leaking, the gas
tends to flow and accumulate in low areas, such as the floor.
Ensure the combination LP/CO detector is properly main-
tained and operational. Observe and follow proper handling
and safety precautions when using propane gas and propane
appliances.
The propane system installed in your motorhome is comprised
of numerous components such as the propane tank, main gas
valve (solenoid-actuated), gas hoses, propane gas regulator, gas
piping, gas appliances, and copper (or steel) tubing lines and
valves within each gas appliance.
As part of your normal maintenance routine (at least once a
year), have a qualified propane service technician perform an
inspection of your entire propane system, including a system
pressure test (appliances, tank, regulator, hoses, piping, and
fittings).
Traveling With Propane
Turn OFF all pilot lights, appliances, and their igniters
(see operating instructions) while the motorhome
is traveling or in motion, and before refueling the
motorhome’s fuel tanks and/or propane containers.
Can cause ignition of flammable vapors, which can lead
to a fire or explosion and result in death or serious injury.
DANGER DANGER
As with all on-board fuel (diesel, gasoline, or other), traveling
with propane does present a level of risk, yet risks can be min-
imized by following a few basic travel precautions.
• Some states prohibit propane appliances to be operated
during travel, especially in underground tunnels, across
bridges, or on a ferry. While traveling, you may also
encounter local restrictions against transporting flam-
mable materials (other than the fuel for the motorhome’s
engine). Make sure you are familiar with the transpor-
tation laws for the areas where you will be traveling,
by checking before hand with the state’s or province’s
Department of Transportation (DOT) or similar regula-
tory office.
• Never travel or stow auxiliary propane gas cylinders
inside the motorhome or inside a non-vented storage
compartment. All ASME certified propane gas tanks
and cylinders have a safety pressure relief system that is
designed to vent propane gas to the atmosphere if a cer-
tain internal pressure threshold is reached. A hazardous
condition exists if gas venting is contained within the
motorhome or an enclosed storage compartment.
• Over time, road vibrations can cause gas fittings and
connections to loosen. Make it part of your routine
motorhome inspection to check all gas fittings, valves,
and connections, for looseness and possible gas leaks.
• Keep your LP/CO detector in good working order and
test it at the beginning of your travel season and least
once a week while traveling.
• Be sure your traveling companions know what to do if
propane gas is detected, either by smell or by the sound-
ing of the LP/CO alarm.
TAKE IMMEDIATE SAFETY
ACTIONS WHENEVER GAS IS DETECTED. Review
and practice evacuation procedures.
• Operating a gas appliance(s) while traveling presents the
risk of fire and/or explosion if the vehicle encounters some
type of road hazard or vehicle damage. To reduce risk,
always travel with gas appliances OFF and the propane
system main valve OFF .
• EXTINGUISH ALL PILOT LIGHTS AND OPEN
FLAMES, AND TURN OFF APPLIANCES WITH
ELECTRONIC IGNITERS BEFORE ENTERING A
FUELING STATION AND DURING FUELING FOR
EITHER VEHICLE FUEL OR PROPANE GAS.
Propane Tank
Over-filling the propane gas tank can result in
uncontrolled gas flow which can cause fire or explosion.
A properly filled tank will contain approximately 80% of
its volume as liquid propane.
An 80% automatic shut-off valve is installed on the
propane gas tank which will automatically prevent
further filling when the gas volume has reached 80%
of tank capacity.
DANGER DANGER
Always shut OFF the motorhome’s engine while
refueling propane tank. Do not smoke. Turn off all
appliances with automatic igniters and do not operate
other ignition sources while refueling.
