fuel & propane SyStem
Verify with your local propane dealer that all required inspections and certications have
been completed on the propane cylinder within the correct time period before relling the
cylinder.
Have the LP system checked for leakage each time a cylinder is relled or after any part of
the propane system has been disconnected.
Hoses, Pipes, Tubes & Fittings
The hoses, pipes, tubes and ttings 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 relled. Look for
signs of deterioration such as cracks or loss of exibility. 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. tting
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. tting has been designed to help restrict the ow
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 rst 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 qualied
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 recreation vehicle is equipped with the “automatic” two-stage regulator, with both
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 re or explosion.
