WARNING : EMPTYING THE LP GAS TANK SHOULD BE DONE BY AN AUTHORIZED LP
GAS DEALER .
IMPORTANT :
The LP Gas System will not operate correctly if the tank is over-
filled . An overfilled tank will not allow proper vapor pressure to develop and
the entire system will cycle between near normal pressure (11 inches of water
pressure) and a much lower pressure which will not allow the appliances to
operate.
The LP (liquid petroleum) gas system supplies
fuel for the range/oven and furnace as shown in
Figure 1 . The LP gas tank, which stores the fuel, is
located in the compartment at the right rear of the
vehicle. The LP gas tank is 42" long and holds 62 lbs.
of LP gas. The tank is equipped with a fill valve,
liquid level outage valve, vapor POL valve, tank float
gauge assembly and a regulator.
SECTION 24F
LP GAS SYSTEM
DESCRIPTION
LP GAS SYSTEM 24F- 1
The gas lines on the MotorHome are laid out so
that most connections are outside the vehicle. The
lines go inside the vehicle only to reach an appliance.
NOTE:
Always leak test the entire LP gas system
after performing any service or maintenance on
the LP gas system . See "Leak Test" later in this
section .
