Main Supply Hose
The main supply hose will be attached from regulator to brass manifold fitting in frame
of coach. Swivel brass nut on main hose will be your final attachment. There are several
things to remember each time the container is removed:
1. Check that ALL fittings are tight.
2. Ensure that ALL connections are tested with leak solution.
3. Open main valve slowly to avoid fast rush of gas to excess flow valve causing gas
freeze up.
4. Listen carefully - a “hissing” sound longer than 1 second may indicate a gas leak.
Close valve and search for leak.
ALL GAS LINES HAVE BEEN
CHECKED WITH AIR PRESSURE.
DEALERS ARE REQUIRED TO
RECHECK AND ADJUST PRESSURE
BEFORE DELIVERY TO CUSTOMERS.
Regulator
The regulator is the heart of your LP gas system with internal moving parts. Its function
is to reduce the high and varied pressure from the LP container to safe and consistent low
operating pressure. The pressure regulator reduces the full cylinder pressure within a
10-13 pound range. The second stage then reduces this inlet pressure to an operating
pressure of 11" W.C. (water column) or 6.35 oz. of outlet pressure to the coach system.
The second stage is adjustable and will need to be adjusted for precise operation. Only
qualified persons should install, adjust or service LP gas regulators. If service is needed,
contact a qualified LP dealer. We suggest this normal maintenance procedure be per-
formed once per year. Please refer to information provided from the manufacturer.
WARNING: LP gas regulators must always be installed with the diaphragm
vent facing downward. Regulators that are not in compartment have been
equipped with a protective cover. Make sure that the regulator vent faces
downward and that the cover is kept in place to minimize vent blockage which
could result in excessive gas pressure causing fire or explosion.
If you travel alternately on wet roads and in freezing weather, be sure your 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.
