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 Regulator
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.r recreation vehicle 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.
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.
