Fleetwood 1998 American Tradition Owner's Manual page 135

The regulator is equipped with a vent. This vent must stay
clean and open. The most common causes of regulator prob-
lems are clogging from corrosion, dirt, insect nests or other
material. Even a small piece of material that finds its way into
the vent can result in improper pressure in the system. This
could damage the system or cause other parts of the system to
fail.
The regulator is mounted so that the vent is facing downward
and is protected from water and dirt by a water-resistant cover.
Be sure the cover is on at all times. If the vent becomes
clogged, it can be cleaned with a toothbrush. If you see
COlTO-
sion, contact a qualified LP gas service technician for a re-
placement regulator.
Your LP gas system will function at low temperatures, as long
as the system components are kept at a temperature above the
vapor point of the LP gas. Ask your LP gas supplier or your
motor home dealer for information on LP gas blends available
in your area and the areas in which you will be traveling.
The availability of gas is reduced at lower temperatures. With
this in mind, keep your LP tank as full as possible during cold
weather. Check the BTU/hr. rating plates on your LP gas
appliances. This information will help you manage your LP
gas use in the best way.
LP gas systems can freeze up in very cold weather. Some
people believe that the regulator or the gas itself freezes.
Actually, the gas does not freeze. The moisture or water vapor
that gets trapped in the system or absorbed by the gas fi'eezes
and causes the problem. This ice can build up and partially or
totally block the gas supply.
