Monarch SE 2004------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Section 7 LP-Gas System | 273
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 unpressurized
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 mis-
alignment 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 continued safety
and the dependable use of the recreation vehicle.
