PROPANE AT LOW TEMPERATURES
Propane systems can and do freeze up in very cold
weather. It is a common misconception that the
regulator or the propane itself freezes. Actually, it is
moisture or water vapor that gets trapped in the
system or absorbed by the propane that freezes and
causes the problem.
Where does the water come from? From a variety of
sources. The propane can be saturated with water
when it comes out of the gas plant or refinery unless
care is taken to see that it is thoroughly dehydrated.
The propane can absorb water while it is transported if
the tank cars contain water; or the propane storage
tanks may have water in them because moist air has
been trapped in the tank because a valve was left
open.
When this water freezes, the ice can build-up and
partially or totally block the propane supply. There are
a number of things you can do to prevent this freeze
up.
1.
Be sure the propane tank is totally moisture-free
before it is filled.
2.
Be sure the tank is not overfilled. This is also a
safety consideration.
3.
Keep the valves on empty tanks closed.
4.
Have the gas tanks purged by the propane service
station if freeze-up occurs.
5.
Have the propane service station inject an
approved antifreeze or de-icer into the tank(s).
6.
Be sure you have the proper propane blend for
your traveling area. If you have the proper
propane blend, it is very unlikely that the propane
is at fault.
If, despite precautions, you do experience freeze-up,
try melting the ice by warming the regulator with a
cloth soaked in warm water if available or regular tap
water. DO NOT USE AN OPEN FLAME. If the problem
persists, ask your propane supplier to service the tank
or regulator as required.
EXTERIOR PROPANE CONNECTION
Your camper maybe equipped with an exterior propane
connector. This connector allows for the attachment of
a portable barbeque that can use the camper’s
propane.
This connection is for a “low-pressure
appliance”. Regular portable BBQ’s are not
designed for low-pressure use.
Some portable BBQ’s
can be converted to low-pressure by changing the
propane valve to a low-pressure valve.
