LP-GAS SYSTEMS
This section contains safety information and operating instructions of the Liquefied Petroleum Gas
(LP-Gas) 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 what is found in this section, can be found in the equipment manufacturer’s manual
in the owner’s information box.
The LP-Gas tank mounted in the motorhome contains liquid petroleum gas that is under high pres-
sure. 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 lighting problems are commonly caused by air in the manifold system or incorrect gas
pressure. Do not attempt to adjust the regulator. Adjustments need to be made by a dealer or an author-
ized service person with the proper equipment.
In higher elevations or extreme cold weather (10° F/-12° C or lower) a shortage of LP-Gas may be
experienced. If LP-Gas is going to be used in higher elevations or cold climates for a long period of
time, have an authorized service person adjust the LP-Gas regulator for these conditions.
Have the LP-Gas 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 the dealer test the system
carefully for leakage, travel vibrations can loosen fittings.
Leaks (identified by the odor of rotten eggs or sulfur) can be easily found by applying a leak detector
solution on all connections. Never light a match, have an open flame or use any spark producing equip-
ment or appliance to test for leaks.
Leaks can usually be repaired by tightening the fittings. 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:
LP-Gas is highly volatile and extremely explosive. DO NOT use matches or a flame to
test for leaks. Only approved LP-Gas 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 LP-Gas
regulators. Only qualified service personnel should perform any maintenance or repair
to the LP-Gas system.

ARNING:
When storing portable LP-Gas tanks that are not connected to an LP-Gas system,
install an approved plug in the tank outlet hole to prevent leaks. Do not store or trans-
port empty LP-Gas tanks, portable tanks, gasoline or other flammable liquids in the
interior area of the motorhome. Keep open flame and park producing materials away
from the LP-Gas area. Shut off all appliances and the primary LP-Gas tank valve when
the motorhome is in storage. If this warning is ignored, a fire or explosion could result.
NOTE:
It may be illegal to travel in some states and Canadian provinces with the primary LP-
Gas valve open. Failure to comply with these State and Canadian province require-
ments may result in fines and/or pose a safety hazard.
