Monarch SE 2004------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Section 7 LP-Gas System | 261
The LP-Gas System section contains information and instruction for the
operation and care of the various Liquefied Petroleum (LP-Gas) system
equipment found in the motorhome. The motorhome is equipped with several
appliances and various equipment which are capable of operation on LP-
Gas. Some items discussed may not be applicable 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 information box.
All components for the motorhome LP-Gas systems are approved for use in
recreational vehicles by a nationally recognized testing laboratory. When prop-
erly handled, LP-Gas is a clean-burning dependable fuel for heat producing compo-
nents. The LP-Gas tank mounted in the motorhome contains liquid petroleum gas
that is under high pressure. As the fuel is used, liquid gas vaporizes and passes
through the tank valve to a regulator that automatically reduces pressure. Low-
pressure gas is then distributed to components through a pipe manifold 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. Usage can be modified by running only one
component at a time. For example, turn off the furnace while using the range. 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 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 primary
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 identified
by the odor of rotten eggs or sulfur) never light a match, have an open flame or
use any spark producing 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 should be used. Unapproved solutions can
damage copper tubing and brass fittings. Never attempt to adjust
LP-Gas regulators. 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 all fittings and accessory control valve.
All fittings tested should be thoroughly rinsed and dried after
testing. Only qualified service personnel should perform any
maintenance or repair to the LP-Gas system.
