an ice-inhibitor as required_
OPERATION OF LP GAS SYSTEM
I f your motor home has the LPG stored in removable
tanks, your appliances will operate from either tank
through a T-fitting and a regulator (refer to Illustra-
tion 13). The first is normally used until empty, then
the tank valve is closed and the second tank opened.
Pilot lights on all appliances need to be relighted after
a tank is switched in this way.
Your system may use LPG stored in a chassis-
mounted tank (optional) (refer to Illustration 13).
The chassis-mounted tank has four controls; the
gas pressure regulator, vapor withdrawal (service)
valve, the fill valve and the gauge. To provide LPG
to appliances, first open the vapor withdrawal service
valve all the way (counter-clockwise) then close it
two-thirds of a burn. When all LPG systems are not
in use, close the valve all the way.
CAUTION: Do not use pliers or a wrench to tighten
valves. If a valve is not leak-tight when closed by
hand, see your LP gas service representative_ Extin-
guish all pilots and open flames. Stop the engine and
stop the auxiliary power generator, if installed,
before filling LPG tanks or fueling your vehicle
tanks_ Pilots and open flames should be extinguished
when the vehicle is under way and, by regulation,
must be extinguished in certain areas such as tunnels
or restricted areas_ Check ahead to areas where you
plan to travel to determine any special regulations
which may apply_
FILLING THE REMOVABLE LPG TANKS
Removable LPG tanks shou Id always be removed
from the storage compartment while being filled.
Take the tank to an LPG supplier or to a service
station which sells LPG. Keep the tank at least 25
feet from the vehicle while it is being filled. Do not
smoke or expose to open flames in or near a
filling area. To remove the tank, first close the tank
valve, then disconnect the tank from the supply line.
NOTE: In removing the fittings, use the proper size
wrench to avoid damaging the fitting. Turn the
fitting clockwise to loosen (reverse thread)_
Remove restraining clamps by lifting the loop release
lever from the strap and opening the strap. With the
line disconnected and the strap loose, remove the
tank by lifting it out.
NOTE: An empty tank weighs approximately 20
pounds or more; handle it carefully to avoid damage
or injury.
To replace the LPG tank, reverse the above procedure.
Be sure to use a counter-clockwise or reverse-thread
motion to tighten the connector. Be sure that the
male fitting is properly al igned with the female re-
ceptacle to avoid damaging the threads. Be sure that
connections are tight, but avoid excessive force.
FILLING THE CHASSIS-MOUNTED LPG TANK
(Optional)
If you have an optional chassis-mounted storage tank,
drive the vehicle to an LPG' supplier or one of the
service stations which sell LPG to have the tank
filled. Look under Gas, Liquified Petroleum, Bottled
and Bulk, in your classified directory or refer to the
service directory available at your dealer. For addi-
tional information, refer to instructions for your
gas appliances provided in your owner's kit.
LPG SYSTEM LEAK CHECKS
For your safety, check for leaks in your gas system
each time the tank is filled o'r before each trip.
Always check the system any time the odor of
garlic is· detected. To perform a leak check, open
the tank valve and spread, a soap-bubble solution
over all connections. Escaping gas will create visible
bubbles to show the location of any leak.
WARNING: Never check for leaks with an open
flame_ If the leak cannot be located, take the unit to
an LPG service representative.
Keep the tank valve closed and turn off all appliances
if the unit is not being used. When operating LPG
appliances, use only one tank at a time to avoid in-
advertently depleting your LPG supply.
LPG LEAK DETECTOR (Optional)
If your LPG system has removable. tanks, an optional
leak detector may be installed. This is a small valve
in the line, near the regulator. Byusing this accessory
