When an LP tank is low, occasionally there is a concentration of garlic-like odor which
may be mistaken for a gas leak. After a change over to a full tank, the odor usually will
disappear. If not, turn off the valve of the LP container and have the system checked by
a qualified technician.

CAUTION:
Remember – POL adapters and fittings have left hand threads.
POL ADAPTER AND LOW PRESSURE
Propane leaves the container through a POL
adapter (Fig. 4-18) with an excess flow valve
built into adaptor, which is attached to the regu-
lator. No sealant is required on a brass to brass
connection.
The excess flow valve provides a large volume
of propane to escape from the bottle should there
be a breakage between container and regulator.
REGULATOR
The regulator (Fig. 4-17) is the heart of your LP gas system and has internal moving
parts. Its function is to reduce high and varied pressure from the LP container to a safe
and consistent low pressure. The inlet valve is the first stage, reducing container pressure
to ten to thirteen pounds. The second stage will reduce the gas from ten pounds to an
operating pressure of 11" W.C. (water column) or 6.35 oz. of outlet pressure to the
motorhome system. The second stage is adjustable and will need to be adjusted for
precise operation. DO NOT attempt to adjust regulator. Have an authorized and compe-
tent technician make any adjustments. We suggest this normal maintenance procedure be
performed once per year.
WARNING:
LP gas regulators must always be installed with the diaphragm
vent facing downward. Regulators that are not in a compartment have been
equipped with a protective cover. Ensure that the regulator vent faces down-
ward and that the cover is in place. This will minimize vent blockage that
could result in excessive gas pressure causing a fire or an explosion.
If traveling on wet roads and in freezing weather conditions, ensure that the LP gas
regulator is protected from road spray. If water enters the vent in the regulator, it may
freeze the pressure controlling diaphragm in the open position so that the container
pressure is applied to the appliances – a hazardous condition. Follow the instruction
given by the manufacturer of the regulator. The vent on the regulator is to be turned
downward position between 5 and 7 o’clock.
MAIN SUPPLY HOSE
The main supply hose will be attached from the regulator to the brass manifold fitting in
the frame of the motorhome. The swivel brass nut on the main hose is the final
attachment.
