(e.g., copper) and flared fittings (e.g., brass). Have your LP gas system leaks
repaired ONLY by a qualified service technician; do not attempt these yourself.
Keep the main valve to the LP gas tank closed and all appliances turned "off"
when the motor home is stored. If any of the valves do not close "leak-tight" by
hand, have those valves examined and repaired by aqualified service technician.
DO NOT, under any circumstances, attempt to use a faulty LP gas system
and/or appliances as such may represent a safety hazard.
Since LP (i.e., liquid propane) gas is more dense than air, the LP gas will
naturally settle to the lowest point in an enclosed space—in the motor home,
this would be the floor. Because of this fact, the CO/LP gas detector (Figure 3-
6) is necessarily mounted close to the floor. To activate the LP-gas sensor on
this detector for the first time, remove the sensor activation strip, if such was not
performed during the pre-delivery inspection. Please check the CO/LP gas
detector to verify that the detector was properly activated and is ready to
provide the necessary protection. If in doubt, please contact any qualified
service technician for more detailed assistance.
If the alarm persists in re-arming and giving further alarms; ventilate the motor

home (by opening doors and windows) and then check for possible LP gas
leaks. If the leak cannot be readily found, then close the main valve to the LP tank and turn "off" all gas appliances and
then take the motor home to a qualified service technician after the ventilation process is concluded and the doors and
windows again shut.
