Propane Tank; Propane Regulator - Thor Motor Coach tuscany 2013 Owner's Manual

Propane has a distinctive odor. If you are unaware of the nature of an
odor contact a Thor Motor Coach dealer. If you smell propane:
• Extinguish any open flames, pilot lights, and all smoking materials.
• Do not touch any electrical switches.
• Shut off the gas supply at the tank valve or gas supply connection.
• Open doors and windows.
• Leave the area until the odor clears.
• Have the gas system checked immediately by a certified RV technician.
Annual maintenance should be conducted on the propane gas appliances and equipment
by an authorized dealer.
The propane tank is mounted to the chassis below the floor between the frame rails and
behind the lower compartment door of your motorhome. The tank needn't be removed,
as it is accessible for filling through a remote fill under the lower compartment door in
the drivers side. The tank and fittings have been completely assembled; however, upon
initial filling, all connections should be checked for leakage by a certified RV technician.
The propane is stored in the tank as a liquid under pressure and vaporizes under the
control of the pressure regulator for use with all of the propane appliances. The propane
in the tank is much colder than the air that surrounds the tank, but as the air temperature
drops closer to the temperature of the liquid in the tank, the liquid doesn't vaporize as
easily. Consequently, the BTU value of the propane drops dramatically. The closer the
tank is to full during cold temperatures, the better the BTU value will be; however, do not
fill the tank to more than 80 percent (80%) of capacity.
Freezing of the propane system is a potential problem during cold temperatures
because of moisture in the propane or supply system. Precautions should be taken to
keep your tank and system free of moisture. Check with your propane service station
about approved antifreeze or deicers, which may be available to reduce the possibility
of a freeze.
The tank has a gauge installed to show the level of propane in the tank. The tank level
can be remotely read from the monitor panel. The monitor panel is usually located in
the hallway.
The propane tank has a regulator installed adjacent to the main shut-off valve. The
regulator controls the pressure to the appliances as required for proper operation. This
regulator has been preset by the regulator manufacturer and should not be adjusted
unless necessary, and then only by a qualified propane service technician.
The regulator has a vent to permit it to breath, allowing the diaphragm to move up and
down, and also allowing a release for excess pressure which may build up. This vent
must be facing downward and should be checked periodically to make sure that it is
clean and free from obstructions. Clogging from corrosion, dirt, insects and other debris
is the most common cause of regulator malfunction.
The propane regulator must always be installed with the diaphragm
vent facing downward. Regulators that are not in compartments have been
equipped with a protective cover. Make sure that the regulator vent faces downward and that the cover
remains in place to minimize vent blockage that could result in excessive gas pressure, causing fire or
explosion.
