Liquid Propane (LP) Gas System
A warning label is conspicuously located near the LP gas container (Figure 2-4); that label reads:
Warning
DO NOT FILL the LP Container(s) to more than 80% of capacity.
Any overfilling of the LP gas container(s) can result in uncontrolled gas flow—a prime condition for a fire or explosion.
The LP container should only be filled to 80% of its capacity; the remainder of the cylinder space is vapor space to
contain expansion of that liquid when subjected to varying ambient-temperature conditions. Filling in excess of 80% of
the liquid volume of the container reduces that vapor space and, thus, creates a condition for possible over-
pressurization of the container.
All LP appliances in your motor home have been approved for use in motor homes by a nationally recognized
testing laboratory (i.e., UL and CSA certified). When properly used, LP gas is a clean-burning fuel which can be
dependably used.
In actuality, the LP container contains liquid propane under high pressure. The liquid, when it passes through
the tank valve to a lower pressure, vaporizes into a gas, and then passes through a regulator to maintain a
constant pressure. This gas, then, is the actual fuel distributed through the LP-gas manifold system to the
LP-based appliances used in your motor home.
LP-appliance-lighting problems are typically caused by an improperly adjusted gas regulator. NEVER attempt to adjust
or reset the gas regulator yourself, as an authorized service technician is needed to make these adjustments.
As a good preventive-maintenance activity, the regulator should be checked semi-annually by a service technician
and also before every extended trip.
Even though the LP-gas system is leak-checked and verified at the factory at
the time of manufacture, normal usage (travel vibrations, etc.) could loosen the
fittings. Consequently, it is wise to check the gas fittings periodically for leak
tightness. One can daub some leak-detector solution (e.g., a “liquid-soap”-like
solution) on all the fittings, connections, and junctures when the system is
under pressure. Should there be any leaks, small bubbles will appear at any
leak sites.
• NEVER use an open flame to test for LP gas leaks or to examine the fluid levels in the fuel tanks.
• After filling any LP system, immediately replace and secure all protective covers and caps.
• After closing the LP valve, close and securely latch the LP door to prevent unintentional access or damage.
• NEVER connect natural gas to the LP gas system—LP gas and natural gas are not interchangeable.
• NEVER use any other “burning” equipment (e.g., charcoal grills, wood stoves, butane lights, propane
lights) inside the motor home—doing so may cause fires and/or asphyxiation.
