SYSTEM COMPONENTS
Hoses
The hoses used in your propane system meet
stringent requirements, and are rated to withstand
many times the pressures encountered in the
system. Check the hoses for weather checking
or other signs of deterioration every time you
have the propane tank filled or serviced. When
you replace hoses, be sure that replacements are
properly rated and approved for RV use.
Propane Regulator
The two-stage regulator produces approximately
11 inches of water column (less than 0.5 psi) to
serve your appliances. Be sure the regulator vent
stays clean and free from obstructions.
The regulator is mounted so that the vent is facing
downward and is protected by a cover. Be sure
the cover is on at all times. If the vent becomes
clogged, it can be cleaned with a toothbrush. If
corrosion is evident, contact a qualified propane
service technician for assistance.
USING PROPANE SYSTEM AT
LOW TEMPERATURES
Your propane system will function at low
temperatures, provided the system components
are kept at a temperature above the vapor point
of the propane. Ask your propane supplier or
your motor home dealer for information on
product blends available in your area and the
areas in which you will be traveling .
The following chart shows the reduction in
available BTU’s/hour under various fill levels as
the temperature drops:
Propane System
WARNING
6. Turn off Propane main valve before filling
Propane container or entering an Propane bulk plant
or motor fuel service station. Turn off all pilot lights
and appliances individually before refueling of motor
fuel tanks and/or Propane containers. When not
individually turned off, automatic ignition appliances
may continue to spark when Propane is turned off at
the container.
7. Do not fill Propane containers to more than
80% capacity. Overfilling can result in uncontrolled
Propane flow which can cause fire and explosion.
A properly filled container holds about 80% of its
volume as liquid. FAILURE TO COMPLY COULD
RESULT IN DEATH OR SERIOUS INJURY.
8. Propane regulators must always be installed with
the regulator vent facing downward. Regulators that
are not in compartments have been equipped with a
protective cover. Make sure that the regulator vent
faces downward and that the cover is kept in place to
minimize vent blockage that could result in excessive
Propane pressure causing fire or explosion.
9. Do not use a wrench or pliers to close the tank
shut-off valve. This valve is designed to be closed by
hand. If a tool is required, the valve probably needs
to be repaired or replaced.
10. If you do not have the special tools and
training necessary, do not attempt to repair
Propane system components.
11. Motor homes stored in enclosed garages must
be well ventilated.
12. Do not modify or alter the Propane plumbing system .
13. If any appliance or piping has been serviced,
ensure that a system leak check has been performed
by a trained technician. This should be verified before
taking delivery of the unit by a trained technician.
!
WARNING
Do not attempt to adjust the regulator. It has been
preset by the regulator manufacturer. If any adjust-
ment is required, it must be made by a qualified
Propane service tech nician using special equipment .
!
WARNING
Propane cylinders shall not be placed or stored
inside the vehicle. Propane cylinders are equipped
with safety devices that relieve excessive pressure
by discharging Propane to the atmosphere.
FAILURE TO COMPLY COULD RESULT IN
DEATH OR SERIOUS INJURY.
