Have the LP system checked for leakage
each time a cylinder is refilled or after any part
of the propane system has been
disconnected.
Single stage regulator
Some models are equipped with a single
stage regulator.
Two stage regulator
The two-stage regulator has the only moving
components in the propane system. Its sole
function is to reduce the pressure from the
propane containers to a safe and consistent
low operating pressure. The first stage
reduces the container pressure to 10-13 lbs.
The second stage reduces the 10-13 lbs. of
pressure further to an operating pressure of
11” W.C. (water column) or 6.35 oz. of outlet
pressure to your appliances.
The second stage is adjustable and will need
to be adjusted by your dealer or qualified
propane service technician for optimum
performance (this adjustment should always
be made with a properly calibrated
manometer). If the pressure is too high, it
affects performance and safety; if the
pressure is too low, your appliances will not
operate correctly.
If your RV is equipped with the “automatic”
two-stage regulator, with both cylinders full of
propane, turn the lever on the regulator
towards the cylinder you wish to use first. This
will now be the “supply” cylinder and the other
the “reserve.” Slowly open both cylinder
valves. The indicator on top of the regulator
will turn bright green. When the cylinder
becomes empty, the indicator will change to
bright orange. Now turn the regulator lever to
the side of the “reserve” cylinder and the
green signal should return. You may now
remove the empty cylinder to have it refilled
without interrupting the flow from the full
bottle. After filling the cylinder, connect the
pigtail hose and slowly open the bottle valve.

The hoses, pipes, tubes and fittings used in
your propane system are designed to
withstand pressures exceeding those of the
propane system. However, because
environment and time can both contribute to
the deterioration of these components, they
must be inspected for wear at regular
intervals.
Be sure to inspect the hose before each
season and when having the tank refilled.
Look for signs of deterioration such as cracks
or loss of flexibility. When replacing the hose
or other propane components, make sure to
always replace them with components of the
same type and rating (check with your
dealer).
Fittings are used to connect the various
system components to each other. The P.O.L.
fitting at the end of the propane supply hose is
made of brass so that pipe sealants are not
necessary to prevent leaking. It also has a
left-handed thread, which means that it is
turned clockwise to remove, and counter-
clockwise to tighten. The P.O.L. fitting has
been designed to help restrict the flow of LP
gas in the event of a regulator failure or hose
malfunction.

Propane regulators must always be
installed with the regulator vent facing
downward. Regulators that are not located
in baggage compartments have been
equipped with a protective cover. Make
sure the regulator vent faces downward
and (if applicable) the cover is in place to
minimize vent blockage that could result in
excessive gas pressure causing fire or
explosion.
Do not use portable fuel-burning
equipment, including wood and charcoal
grills and stoves, inside the RV. The use of
these items inside a RV may cause fires or
asphyxiation (inability to breathe).
