expansion. The high pressure of the vapor in
the tank is reduced in two stages as it makes its
way to your appliance. The tank pressure will
vary with temperature and altitude, but it may
be in the range of 100 to 250 pounds per square
inch (psi) or more. It is reduced by a pressure
regulator to about 12 psi in the first stage and
then to about 6.25 ounces in the second stage.
The 6.25 ounces psi can also be expressed as 11
inches of water column.
The LP gas system is designed and built to rigid
standards and tested before leaving the factory.
Your dealer also tests the system prior to
customer delivery.
Except of simple maintenance and occasionally
tightening a connection, you should take your
unit to an authorized dealer for LP gas
problems. The LP gas tank should always be
filled by an authorized LP supplier.

ASPECTS OF LIVING AROUND LP GAS.
CLIMATE DIFFERENCES
The appliances in your vehicle will not function
if the LP gas does not vaporize. Propane bas
become the main type of LP gas used in RV’s in
recent years. Butane should not be used. The
LP gas dealer will have the correct or blend for
this locale. If you plan on traveling from a
warmer climate to a cold climate, check with
your local gas dealer to see if the blend he
supplies is appropriate for the part of the
country you plan on visiting.
OPERATION
To operate any LP gas appliance, the LP gas
tank’s service valve must be OPEN. When first
used, or after a refill, there may be some air in
the gas lines that will escape when the range
burner or similar gas valve is opened. The air
may extinguish the match or igniter the first
time or two you attempt to light a stove burner.
Also remember that when you close the tank’s
service valve, some gas will remain in the lines.
To completely bleed the lines of gas, close the
tank valve and light the range burner. When
the flame burns out, turn off the appliance.
GAS LINE CHECK
Check the gas line connection and all other
connections regularly. To check, turn OFF all
burners and pilot lights. Open all doors and
windows. OPEN the LP gas tank service valve
and use soapy water or an approved leak
detector fluid to test all line connections. DO
NOT use products that contain AMMONIA or
CHLORINE. The appearance of bubbles in the
soapy solution indicates a leak. Tighten the
connections with two (2) open-end wrenches
until the bubbles stop. If this does not take care
of the leak, contact your gas dealer. DO NO
OVERTIGHTEN.
GAS TANK REGULATOR FREEZE-UP
LP gas regulator freeze-up can be prevented if
owners are aware of its causes. Freeze-up may
be caused one of these things: moisture in the
tank, an overfilled tank or a greater vapor
withdrawal demand than the tank can deliver at
a particular temperature.
Freeze-up occurs more frequently in cold
weather since liquid gas does not vaporize as
quickly. This, along with a higher demand, can
cause frosting of the tank and regulator.
Moisture may enter the tank in the LP gas
through condensation if air is allowed to enter
the tank through an open valve. This can be
