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 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.
USING THE PROPANE SYSTEM
After your recreation vehicle is completely set up use the following steps for propane
operation:
1. Close ALL burner valves, controls and pilot light valves.
2. Open the main valve in the propane tank slowly to avoid a fast rush of propane vapor
through the excess flow valve causing propane “freeze-up.” Should you experience
propane “freeze-up,” close the main valve and wait 15 minutes before trying again.
3. Listen carefully as propane begins to flow. If a hissing noise is heard for more than
one or two seconds, close the main valve and contact your recreation vehicle dealer to
have the propane system tested.
4. Light the appliances as needed and directed in the appropriate appliance
manufacturer’s owner manual located in the Warranty Packet.
Keep the propane container valves closed at all times unless you are using the propane gas
system or are having the propane container filled.
Make sure that you read and fully understand ALL safety requirements for handling
and operation of the propane system.
The Warranty Packet contains manufacturer’s user guides for the various appliances
hooked to your propane system.
The propane system provides added benefits to your camping enjoyment; however, it must
be handled with care. If you have any questions or concerns, consult with your dealer
and/or the specific manufacturer.
If you have double cylinders on your recreation vehicle, use only one at a time. Otherwise,
the propane supply will be drawn equally from both cylinders until the supply has been
totally exhausted. Using one cylinder until it is empty, then using the second cylinder will
allow you to fill the empty cylinder at your convenience without running totally out of
propane.
