PROPANE SYSTEMS
This section contains safety information and
operating instructions for the propane system
and related equipment in the motorhome. Some
items discussed may not be applicable to all
motorhomes. More detailed information with
CAUTION or WARNING instructions for
various equipment, other than items within
this section, can be found in the equipment
manufacturer’s manual in the owner’s
information box.
NOTE:
Some appliance displays and appliance
manuals may refer to LP-Gas as a fuel
source; however, the actual fuel source
used and required for these appliances
is propane. The phrase “LP-Gas” is
synonymous with not only propane,
but butane and propane/butane
mixtures. Since propane is the actual
fuel required, the term “propane” will
be used throughout this manual except
for references to third party appliances
(such as the refrigerator) that include
the term “LP-Gas” on their displays or
other literature.
The propane tank mounted in a curbside bay is
under high pressure. As fuel is used, the liquid
vaporizes and passes through the primary tank
valve to a regulator that reduces pressure. Low-
pressure gas is then distributed to components
through a pipe manifold system.
Component ignition problems are commonly
caused by air in the manifold system or incorrect
gas pressure. DO NOT attempt to adjust the
regulator. Adjustments must be made by a
dealer or an authorized service personnel with
the proper equipment. In higher elevations or
extreme cold weather (10° F./-12° C. or lower)
a shortage of propane may be experienced. If
propane is going to be used in higher elevations
or cold climates for a long period of time, have
authorized service personnel adjust the propane
regulator for these conditions.
Have the propane system tested by an
authorized dealer or service center at least once
a year and before every extended trip. The test
will include having the system checked for leaks
and the regulator pressure checked and tested
for functionality. Although the manufacturer
and dealer test the system carefully for leakage,
travel vibrations can loosen ttings.
WARNING:
When storing portable propane tanks
that are not connected to a propane
system, install an approved plug in the
tank outlet hole to prevent leaks. DO
NOT store or transport empty propane
tanks, portable tanks, gasoline or other
flammable liquids in the interior area of
the motorhome. Keep open flame and
spark producing materials away from
the propane area. Shut off all appliances
and the primary propane tank valve
when the motorhome is in storage.
If this warning is ignored, a fire or
explosion could result.
Leaks (identied by the odor of rotten eggs or
sulfur) can be found by applying a leak detector
solution on all connections. Never light a match,
have an open ame or use any spark producing
equipment or appliance to test for leaks. Leaks
can usually be repaired by tightening the ttings.
If not, shut off the primary gas valve at the tank.
Hand-tighten the primary valve only. DO NOT
use a wrench or pliers as over tightening may
damage valve seats and cause leaks. If a leak is
suspected, immediately see an authorized dealer
or service center for repairs.
WARNING:
Propane is highly volatile and extremely
explosive. DO NOT use matches or a
flame to test for leaks. Only approved
propane leak testing solution for leak
detection should be used. Unapproved
solutions can damage copper tubing
and brass fittings. A liquid dish soap
solution of 10 parts water may be used.
Shake the solution until bubbles form
and then apply the mixed solution to
fittings and accessory control valves.
All fittings tested should be thoroughly
rinsed and dried after testing. Never
attempt to adjust propane regulators.
Only qualified service personnel should
perform maintenance or repairs to the
propane system.
NOTE:
It may be illegal to travel in some
states and Canadian provinces with the
primary propane valve open. Failure to
comply with these State and Canadian
province requirements may result in
fines and/or pose a safety hazard.
