Propane Systems
PROPANE SYSTEM
PROPANE GAS
Propane is a colorless and odorless gas that, in the liquefied
state, resembles water. Mercaptan, an odorant described
by many people as having an odor similar to “rotten eggs,”
is added as a warning agent. When a propane container is
low, occasionally 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 or LP (liquefied petroleum) gas is a clean and effi-
cient form of energy when proper handling and safety precau-
tions are observed. The propane system in your RV furnishes
the fuel for cooking, heating and hot water. Propane can also
be used as an alternative energy source for refrigeration. The
propane fuel system is comprised of numerous components
such as the propane container, hoses, the propane gas regu-
lator, piping and copper tubing lines to each appliance. Pro-
pane is heavier than air; the gas tends to flow to lower areas
and will sometimes pocket in these low areas, such as the
floor.
Maintenance
Although both Grand Design RV and your selling dealer care-
fully test for leakage, travel vibrations can loosen fittings. Have
the propane system checked at all connections soon after the
purchase of your RV, and after the initial filling of the propane
tanks. Continued periodic checks of the propane system at
5,000 miles of travel (or at least once a year), by a qualified
propane service representative as part of your normal mainte-
nance is recommended.
PROPANE LEAK TEST
Leaks may be found 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 a quali-
fied propane service representative immediately.
