To minimize or negate this possibility, always keep the main valve to the LP gas tank closed when the system is not in
use. When the LP tank is empty, keep the main valve closed until re-filling is to be performed—this process will keep
any moisture-laden air from back-flowing into the gas system and trapping unwanted moisture in the LP gas tank.
If an empty LP gas tank has been exposed to the atmosphere for an extended time, let a qualified service technician
purge the tank before its next filling operation.
Important
When a LP gas regulator is installed or re-installed, the regulator must
always be installed with the gas diaphragm vent facing downwards.
For more information, consult the manufacturer’s literature in your Owner’s
Information Package that came with the motor home.
CO/LP Gas Detector
Warning
Liquid propane (LP) is extremely flammable and, when contained, explosive
whenmixed with air. Consequently, never check for leaks in LP gas lines or
appliances with an open flame or sparking devices. Do not use any ammoniated
or chlorinated household-type detergents for “bubble testing” possible leak
sites—these detergents may generate fissures or cracks on the metal tubing
(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 faultyLP 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 3-9)
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.
