LP-GAS SYSTEMS
This section contains information and instruction for the operation and care
of the Liquefied Petroleum (LP-Gas) system and related equipment in the
motorhome. The motorhome has appliances and equipment which either oper-
ate on or are part of the LP-Gas system. Some items discussed may not be appli-
cable to all motorhomes. More detailed information with CAUTION or
WARNING instructions for the various equipment, other than what is found in
this section, can be found in the manufacturer's manual in the owner's informa-
tion box.
The LP-Gas tank mounted in the motorhome contains liquid petroleum gas that is under high pres-
sure. As the fuel is used, liquid gas vaporizes and passes through the tank valve to a regulator that auto-
matically reduces pressure. Low-pressure gas is then distributed to components through a pipe mani-
fold system.
Component lighting problems are commonly caused by an improperly adjusted gas regulator. Do
not attempt to reset the regulator. Adjustments need to be made by a dealer or an authorized service
person.
In higher elevations or extreme cold weather (10° F/-21° 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 peri-
od of time, have an authorized service person adjust the LP-Gas regulator for these conditions.
Have the LP-Gas system checked by an authorized dealer at least once a year, and thereafter before
every extended trip. Although the manufacturer and the dealer test the system carefully for leakage, travel
vibrations can loosen fittings.
Leaks can be easily found by applying a leak detector solution on all connections. Leaks can usually be
repaired by tightening the fittings. If not, shut off the main gas valve at the tank. Immediately see an
authorized dealer for repairs. Hand tighten the tank valves only. Do not use a wrench or pliers as over
tightening may damage valve seats and cause leaks. If a leak is suspected (which can be easily identi-
fied by the odor of rotten eggs or sulfur) never light a match, have an open flame or use any spark pro-
ducing equipment or appliance.
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
detergent 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 fit-
tings tested should be thoroughly rinsed and dried after testing. Never attempt to
adjust LP-Gas regulators. Only qualified service personnel should perform any main-
tenance or repair to the LP-Gas system.
