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.
Generally, loose fittings can be tightened (with “non-sparking” tools) to stop the leaks. If this process doesn’t
work, then one must shut off the main gas valve at the LP cylinder(s) and immediately consult an authorized
service technician to determine what repairs are necessary. Leaks may also be detected by noting the sulfurous
odor (i.e., rotten eggs) associated with LP gas [caused by an additive added to the normally odorless LP gas].
DO NOT search for a leak by using a match or open flame.
Warning
When the motor home is not in use, be sure to close the main LP gas valve at the tank.
When the LP gas tank is to be refilled, close the main valve to preclude the chance of
the pilot lights possibly igniting fumes from the LP fuel. As some LP-gas appliances
(e.g., refrigerator, furnace, water heater) have Direct Spark Ignition (DSI) systems, it is
very important that these appliances be turned “off” when the LP gas is “off.” The DSI
boards will continue to work (i.e., generate an ignition spark) even when there is no LP
gas available.
LP Gas Regulator
The LP gas regulator (Figure 2-4, center of picture) is the most critical element of the LP-gas distribution
system. The regulator converts the high-pressure LP gas from the tank into a reduced-pressure LP-gas supply
suitable for use in the various appliances in the motor home. One should regularly inspect visually the regulator
system.
