DRIVING & SAFETY INSTRUCTIONSLP-appliance-lighting problems are typically caused by an improperly adjusted gas regulator. NEVER attemptto adjust or reset the gas regulator yourself, as an authorized service technician is needed to make theseadjustments. As a good preventive-maintenance activity, the regulator should be checked semi-annually by aservice 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, normalusage (travel vibrations, etc.) could loosen the fittings. Consequently, it is wise to check the gas fittingsperiodically for leak tightness. One can daub some leak-detector solution (e.g., a “liquid-soap”-like solution) onall the fittings, connections, and junctures when the system is under pressure. Should there be any leaks; smallbubbles will appear at any leak sites.Generally, loose fittings can be tightened (with “non-sparking” tools) to stop the leaks. If this process doesn’twork, then one must shut off the main gas valve at the LP cylinder(s) and immediately consult an authorizedservice technician to determine what repairs are necessary. Leaks may also be detected by noting the sulfurousodor (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.WarningWhen 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 ofthe 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 isvery important that these appliances be turned “off” when the LP gas is “off.” The DSIboards will continue to work (i.e., generate an ignition spark) even when there is no LPgas available.LP Gas RegulatorThe LP gas regulator is the most critical element of the LP-gas distribution system. The regulator converts thehigh-pressure LP gas from the tank into a reduced-pressure LP-gas supply suitable for use in the variousappliances in the motor home. One should regularly inspect visually the regulator system. If any damage orcorrosion is noted, contact an authorized service technician to inspect and repair or replace the regulator.Do not attempt to adjust the regulator yourself; the regulator has been pre-set at the factory. Only a qualifiedLP service technician using specialized equipment should adjust the regulator.LP Distribution SystemThe primary LP distribution system in the motor home is a pipe manifold running the length of the motorhome. The secondary distribution lines running from this main distribution system are usually copper tubingwith flare fittings. If any of the gas lines break, do not attempt to splice them—always run new lines to2-7
