Lp-Gas Hose Inspection - Holiday Navigator 2003 Owner's Manual

It is suggested by the hose manufacturer that the Liquid Propane Gas
(LP-Gas) supply hoses, used on the motorhome, be subject to regular inspection.
As a guideline, we suggest that all flexible LP lines connecting the slide-out,
appliances, or tanks be inspected in the spring and fall of each year by a
qualified RV technician.
According to the manufacturer, the inspections should consist of the
following procedures and be performed when the hose is not under pressure:
1. INSPECTION: Inspect the outside cover of the hose for blistering,
abrasion or cuts and coupling slippage. Cuts in the hose cover,
which expose or damage the reinforcement, is cause for replacement.
Hose strength is controlled by the plies of the reinforcement and
damage in this area cannot be tolerated. Small cuts, nicks, or
gouges in the cover that do not go completely through the cover
will not be cause for replacement of the hose.
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.
2. Damage to the textile reinforcement or wire braid is cause for
hose replacement. Wire braid reinforced hose, which has been
kinked or flattened so as to permanently deform the wire braid in
the un-pressurized state, shall be removed from service.
3. Blistering or loose outer cover is cause for hose replacement.
4. Examine couplings for slippage. Slippage is evidenced by the
misalignment of the hose and coupling and/or the scored or
exposed area where slippage has occurred. Any evidence of
slippage is cause for hose replacement.
5. 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
of the LP-Gas hose.
NOTE: Only a qualified RV technician should complete replacement
of LP-Gas components.
It is also suggested, that the flexible LP-Gas supply lines on your
recreational vehicle be replaced every ten (10) years. The manufacturer of the
LP-Gas supply lines recommended this schedule after performing extended
testing and have determined that the failure rate may rise after this period of
time. The motorhome manufacturer recommends following these guidelines to
assure your continued safety and the dependable use of your recreation vehicle.
