SECTION 7 – FUEL SYSTEM
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.

OSES IPES
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.
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.

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).
After the RV is completely set up and you are prepared for camping enjoyment,
use the following steps for propane operation:
