Fleetwood 1999 Discovery Parts And Service Manual page 113

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 ventcan 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 corrosion, contact a qualified LP gas service technician
for a replacement 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 suppli-
er 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 BTUlhr. 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
freezes and causes the problem. This ice can build up and
partially or totally block the gas supply.
