SECTION EIGHT
MANOMETERS
The manometer is the best way to accurately determine
propane pressure . There are two different styles of
manometers: Gauge and
U-tube . Propane pressure
is measured in Inches of
Water Column . This is
the amount of pressure
applied to one side of
a U-shaped tube filled
half way with water .
The amount of pressure
needed to raise the column
of water 11” represents 11
Inches of Water Column .
PROPANE HOSE INSPECTION
The hose manufacturer suggests that a flexible
propane supply hose undergo regular inspection . As a
guideline, it is recommended that all flexible propane
lines connecting the slide-out, appliances and tanks
be inspected in the spring and fall of each year by a
qualified 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 propane 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 .
Cause for hose replacement:
• Damage to the textile reinforcement or wire braid;
wire braid reinforced hose, which has been kinked
or flattened so as to permanently deform the wire
braid in the non-pressurized state .
• Blistering or loose outer cover .
• Slippage; evidenced by the misalignment of the
hose and coupling and/or the scored or exposed
area where slippage has occurred .
WARNING:
Check for leaks on all connections each time the
remote hookup is used . If a leak is detected, turn off
the primary valve on the propane tanks . Contact a
qualified service center for the repairs .

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 .
CAUTION:
Only a qualified service technician should perform
repairs or component replacement .
