HEATING & AIR CONDITIONINGA LP gas-distribution system distributes the gas to those appliances using such in the motor home. The“heart” of this LP gas distribution system is the regulator and that regulator should only be adjusted by aqualified service technician. Most of the problems encountered in lighting the pilots of these appliancesare caused by regulator mis-adjustments.The major component of the LP gas supply is a manifold pipe which runs lengthwise underneath themotor home floor. From this manifold, the various gas appliances are connected by copper tubing withflared fittings so that connections and disconnections can readily be made, as needed.Should any of the secondary tubing develop a leak, either on the tubing proper or at the fittings; do notattempt to splice any of these lines. Instead, have a qualified service technician run a new length oftubing to the appliance of concern and then have that line leak-tested before placing it in normaloperation. To remove, repair, or replace any gas-operated appliance; always close the main gas valve atthe LP tank—this measure will provide an additional element of safety to prevent gas leakage andpossible, subsequent explosion hazards.However, if a gas leak is noted or suspected, turn “off” the main valve and keep the LP gas system “off”until that system is inspected by a qualified service technician as soon as possible. Do not delay inaddressing any possible gas leaks with appropriate service because of the inherent hazards to safety.WarningWhen the motor home is not being used, the main LP gas valve must be turned “off.”Also, turn “off” the main valve when the LP gas tank is to be refueled to avoid thepossibility of ignition fuel fumes by the pilot lights. All gas valves on the gas-operatedappliances with Direct Spark Ignition (DSI) should also be in the “off” position duringrefueling and/or maintenance operations. DO NOT store LP, diesel fuel, propane,butane, or other flammable liquids inside the vehicle as these represent a very real firehazard and possible threat to life.LP Tank Filling PracticesAny LP gas tank associated with the motor home should never be filled to more than 80% of totalcapacity; filling should always be done only when the motor home is leveled. If the motor home is notlevel, the tank may be overfilled (i.e., more than 80% of capacity) and, thus, subject the motor home topossible fire or explosion from resultant uncontrolled gas flows.3-5
