Damage to the regulator can occur when the
tank is over
fi
lled. The regulator is designed
to work with vapor only. This is why the tank
is
fi
lled to only 80% of its liquid capacity.
The other 20% allows for vaporization of the
liquid. The primary vapor valve is located in
the vapor section of the tank. In an over
fi
lled
tank, lique
fi
ed petroleum can
fi
ll the regulator.
Vaporizing liquid can freeze the diaphragm.
High tank pressure on a frozen diaphragm can
cause a rupture and result in erratic pressure
regulation. This is why it is important to
have the LP-Gas pressure checked for proper
pressure and accurate regulation during
appliance operation. Erratic pressure regulation
dramatically affects refrigerator operation on
LP-Gas.
WARNING:
DO NOT attempt to adjust the
regulator. Adjustments require special
equipment. Failure to follow these
instructions may result in a fire or
explosion, and can cause severe personal
injury or death. DO NOT operate
LP-Gas appliances until the LP-Gas
pressure is checked and a leak down test
is performed.
Manometers:
The manometer is the best way to accurately
determine LP-Gas pressure. There are two
different styles of manometers: Gauge and
U-tube. Gas pressure is measured in Inches of
Water Column. This is the amount of pressure
applied to one side of a U-shaped tube half
fi
lled
with water. The amount of pressure needed to
raise the column of water 11" represents 11
Inches of Water Column.
TIP:
Attach the
manometer gauge to
the accessory hookup
line to avoid loosening
any interior LP-Gas
line connections.
LP-GAS HOSE INSPECTION
The hose manufacturer suggests that a
fl
exible
LP-Gas supply hose undergo regular inspection.
As a guideline, we suggest that all
fl
exible LP-
Gas lines connecting the slide-out, appliances
and tanks be inspected in the spring and fall of
each year by a quali
fi
ed RV technician.
Inspection tips:
Hose strength is controlled by the plies of
reinforcement. Damage in this area cannot
be tolerated. It is important that if a damaged
LP-Gas hose is found, the source of the damage
be determined and corrected prior to the
replacement. Small cuts, nicks, or gouges that do
not go completely through the cover are not cause
for replacement of the hose. Inspection should be
performed when the hose is not under pressure.
NOTE:
Pricking of the cover in the
manufacture of this type of hose is
common and necessary for satisfactory
hose performance. Consequently, the
uniformly pricked cover should not be
viewed with alarm.
Cause for hose replacement:
Damage to the textile reinforcement or
wire braid
Wire braid reinforced hose that has kinked or
been
fl
attened so as to permanently deform
the wire braid in the un-pressurized state.
Blistering or loose outer cover.
Slippage evident by the misalignment of
the hose and coupling and/or the scored
or exposed area where slippage has
occurred.
