Section 7: Fuel System
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 pro -
pane 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
cylinders full of propane, turn the lever on the regulator towards the cylinder you wish to
use first. This will 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 cyl-
inder becomes empty, the indicator will change to bright orange. 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.
Refer to the manufacturer’s pamphlet included in your warranty packet and follow all safety
instructions and warnings listed.
NOTE: Regulator appearance and type may vary by model.
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.
