Propane Regulator
Propane is under high pressure in the tank. The purpose
of the regulator is to reduce the pressure inside the tank
to allow for safe use.
W ARNING
To avoid potential problems, have your propane
system checked at least once a year by an autho-
rized service center and after each extended trip.
W ARNING
NEVER test for a leak by lighting a match or hav-
ing an open flame where you suspect a leak. Take
to an authorized service center.
Regulator Freeze-Up
The term ‘regulator freeze-up’ is a misleading one. Regu-
lators and propane do not freeze. However, the moisture
that can be contained in the propane will freeze as the
propane expands and cools passing through the regula-
tor. This freezing of the moisture in the propane can build
up and partially or totally block the passage of the pro-
pane through the regulator. Freezing can also occur
when outside temperatures are low enough to contribute
to the freezing of the moisture in the propane.
The source of the moisture is varied. It can occur at the
refinery or propane bulk plant, in the cars used to trans-
port the propane, or even within your own propane tanks.
Moisture in a propane tank can occur when a tank ser-
vice 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 the fact
that heat is being transferred through the walls of two
regulators instead of only one.
Tips to help prevent regulator freeze-up:
•
Be sure your propane tank is free of moisture before
refilling.
•
DO NOT overfill the propane tank.
•
Be sure to keep the service valve on an empty tank
closed.
•
If freezing occurs, have your propane dealer purge
the tank before refilling.
•
Check with your dealer to determined which deicing
agent is approved to add to the propane tank.
•
Keep the regulator covered at all times.
Other Cold Weather Factors
As outside temperatures drop, the BTU value of the pro-
pane is lessened. The colder propane in the tanks
requires heat from the surrounding air to vaporize. This
lowering of BTU value can significantly affect the perfor-
mance of the system. Keeping your propane tanks as full
as possible in cold weather and reviewing the BTU/hr.
rating plates on propane appliances will help ensure
proper propane management.
Propane Pigtail
The propane pigtail is a hose used to connect to the
regulator on the tank through which the propane 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 propane flow and
prevents propane from flowing unless the connection is
tight.
NOTE:
The connection at the propane tank will shut down in
extreme heat (240° - 300° Fahrenheit).
