HOW TO LEAK TEST
T
HE PROPANE SYSTEM
Use an appropriate propane leak detector
solution or create a soapy water solution. The
propane leak detector solution can be
purchased at most dealerships (if soapy water
is used, make sure that the soap used does
not contain ammonia or chlorine). Apply the
propane leak detector solution to all propane
piping connections. If a leak is present, the
solution will bubble at the connections.
If a leak is detected
1. Execute your family safety plan.
2. Turn off the propane at the cylinder(s).
3. Turn off all appliances that utilize propane.
4. Unplug the shore line power cord.
5. Disconnect the 12-volt auxiliary battery (if
so equipped).
6. Contact your dealer for a service
appointment. Have the propane system
repaired before using it again.
ASME TANK
Propane is stored in the pressurized tank in a
liquid state. As the propane is released from
the tank , it changes to vapor that is then used
for the operation of the appliances. Propane
will not run through the appliances in the
liquid state. The volume of liquid propane
increases approximately 1-½% for every 10°F
(5.5°C) it is warmed. Heat the propane 100°F
(55°C) and the tank liquid volume will
increase 15%. That is why it is imperative to
leave sufficient space inside the cylinder to
allow for natural expansion of gas during
warmer weather. The following label should
be kept permanently affixed to your RV.
Fig. 9.2 “Do not fill to more than 80%” label
Fig. 9.3 ASME propane tank
The factory-installed propane tank is an
ASME tank mounted under the floor of the
motorhome. Because the tank is not
removable, the motorhome will need to be
driven to a propane fill station. Be sure to
read, understand, and follow all information
supplied with your motorhome by the propane
tank OEM. If you have further questions,
consult your RV dealer, the OEM or Jayco
Customer Service.
The main shut off valve must be kept closed
at all times unless you are using the propane
system or filling the propane tank. When the
tank is disconnected from the hose, install the
valve cover that is attached so the tank . This
is required by the National Fire Protection
Agency (NFPA), other applicable local codes
and for your own safety.
IT IS STRONGLY RECOMMENDED
THAT YOU HAVE A PROFESSIONAL
TEST THE RV PROPANE SYSTEM FOR
LEAKS ONE TIME EACH YEAR AS
PART OF NORMAL MAINTENANCE.
