THE PROPER STEPS TO PREVENT A REOCCURENCE.
HAVE THE SYSTEM CHECKED BY YOUR LP SUPPLIER.
Other Cold Weather Factors
As outside temperatures drop, the BTU value of the LP gas
is lessened. The colder liquid LP in the tank/s requires heat
from the surrounding air to vaporize. This lowering of BTU
value can significantly affect the performance of the system.
Keeping your LP tanks as full as possible in cold weather and
reviewing the BTU/hr rating plates on LP appliances will help
insure proper LP management.
LP PIGTAIL
The LP pigtail is a hose
used to connect to the
regulator on the tank
through which the LP fuel
flows. This safety feature
is generally recognized by
the large green nut that
attaches to the outside of
the valve on the regulator.
It limits excessive gas
flow and prevents gas
from flowing unless the connection is tight.
NOTE:
THE CONNECTION AT THE LP TANK WILL SHUT
DOWN IN EXTREME HEAT (240˚-300˚ FAHRENHEIT.)
LP DETECTOR
In the Event of an Alarm:
If the detector senses
the presence of LP
gas, the red light will
turn from green to red,
accompanied by an
audible alarm. If the
alarm sounds:
1.) Immediate evacuate
all occupants from
the recreational
vehicle.
2.) Extinguish any open flames, pilot lights and all smoking
material.
3.) DO NOT touch any electrical switches.
4.) Shut off the gas supply at the tank.
5.) Open doors and windows to ventilate.
6.) DO NOT USE THE RANGE HOOD OR OTHER POWER
VENTS.
7.) The alarm will continue to sound as long as LP gas is
detected or until turned off.
DO NOT
adjust or repair the regulator. It is preset at the
factory to certain specifications and should only be adjusted
by a qualified propane service technician. To avoid potential
problems, have your LP gas system checked at least once a
year by an authorized service center and after each extended
trip.
NEVER
test for a leak by lighting
a match or having an open flame
where you suspect a leak.
REGULATOR FREEZE-UP
The term ‘regulator freeze-up’ is a misleading one. Regulators
and LP gas do not freeze. However, the moisture that can
be contained in the gas will freeze as the gas expands and
cools passing through the regulator. This freezing of the
moisture in the gas can build up and partially or totally block
the passage of the gas through the regulator. Freezing can
also occur when outside temperatures are low enough to
contribute to the freezing of the moisture in the gas.
The source of the moisture is varied. It can occur at the
refinery or gas bulk plant. in the cars used to transport
the gas, or even within your own LP tanks. Moisture in an
LP tank can occur when a tank service valve is left open,
allowing moist air to enter and become trapped.
A two-stage regulator helps reduce the possibility of freeze-
up because of its larger orifice size and that heat is being
transferred through the walls of two regulators instead on
only one.
Bright
Idea
Tips to help prevent
regulator freeze-up:
• Make sure your LP tank is free of moisture
before refilling
• DO NOT overfill the LP tank
• Be sure to keep the service valve on an
empty tank closed
• If freezing occurs, have your LP dealer
purge the LP tank before refilling
• Check with your dealer to determined
what deicing agent is approved to add to
the LP tank
• Keep the regulator covered at all times
NOTE:
IF FREEZE-UP DOES OCCUR, SHUT THE LP OFF
AT THE TANK. A FROZEN REGULATOR MAY PERMIT LP
GAS TO FLOW AT HIGH PRESSURE, RESULTING IN LEAKS
AT APPLIANCES OR IN THE LINES. NEVER ATTEMPT TO
THAW WITH AN OPEN FLAME. A SMALL LIGHT BULB CAN
SOMETIMES BE USEFUL TO PROVIDE HEAT AND AID THE
THAWING PROCESS. ONCE THAWED, BE SURE TO TAKE
WARNING
‘WARNING’ indicates a hazardous situation which, if not avoided, could result in death or serious injury.
