LP-GAS SYSTEMS

This section contains safety information
and operating instructions for the Liquefi ed
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 items within
this section, can be found in the equipment
manufacturer's manual in the owner's
information box.
The LP-Gas tank mounted in the front fuel
bay contains LP-Gas that 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 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
authorized service personnel 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 fi ttings.
WARNING:
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 transport empty LP-Gas
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 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.
Leaks (identifi ed 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 fl ame or use any spark producing
equipment or appliance to test for leaks. Leaks
can usually be repaired by tightening the fi 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:
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 maintenance or repairs to the
LP-Gas system.
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 requirements may result in
fines and/or pose a safety hazard.

LP-GAS DETECTOR

The LP-Gas detector is required safety
equipment in RVs. American National
Standards Institute (ANSI) A119.2 - Fire
& Life Safety 3-4.8 LP Gas Detectors states
" A LP-Gas detector must be installed in any
RV that contains an LP-Gas appliance and an
electrical system. The LP-Gas detector must be
listed as suitable for use in recreational vehicles
under the requirement of UL 1484 Residential
Gas Detectors, and installed according to the
terms of its listing."
