Section 7: Fuel & Propane System
Propane Use and Safety
Propane is a colorless and odorless gas that, in the lique-
fied state, resembles water. An odorant (usually a sulfur
compound) is added as a warning agent. If you smell
propane within the vehicle, quickly and carefully per-
form the procedure listed on the propane system label.
This label has been placed in the vehicle near the range,
for models equipped with a propane systemWhen a pro-
pane container is low, there may be a concentration of
an onion or garlic-like odor, which can be mistaken for a
propane gas leak. After the propane container has been
refueled, the odor will usually disappear. If not, turn off
the valve(s) and have the propane system inspected by
your dealer or qualified propane service representative.
Propane Leak Test
Leaks may be found easily with a soapy water solution.
Do not use a solution containing ammonia or chlorine
when locating leaks. These products are corrosive to copper gas lines and brass fittings,
which could result in deterioration of the copper and brass components.Apply the soapy
solution to the outside of the gas piping fittings. If a leak is present, the soapy solution will
“bubble” at the leak point. If a leak is indicated, shut off the propane system valve(s) and
contact your dealer or qualified propane service representative immediately.
Using the Propane System
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 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 dealer to have the propane
system tested.
4. Light the appliances as needed and directed in the appliance manufacturer’s own-
er 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 propane system must be handled with care. If you have any questions or concerns,
consult with your dealer and/or the specific appliance 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 to-
Propane System Label
Never use an open flame to test for a propane leak. Do not check for leaks
using products that contain ammonia or chlorine; these products can cause
cracks to form on the metal tubing and brass fittings
