Main Supply Hose - Low Pressure; Regulator - Jayco COVE 2002 Owner's Manual

Main Supply Hose - Low Pressure

The main supply hose will be attached from regulator to brass manifold fitting in frame of trailer.
Swivel brass nut on main hose will be your final attachment. Several things to remember each time
tank is removed:
Fig. 4-19
1. Be sure ALL fittings are tight.
2. Be sure 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.
If you experience a gas "freeze-up," close the main valve and wait 15 minutes before trying
again.
4. Listen carefully - a "hissing" sound longer than one 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 tank to safe and
consistent low operating pressure. The inlet is the
first stage and reduces tank pressure to 10-13 pounds.
The second stage will reduce the 10-13 pound
pressure to an operating pressure of 11" W.C. (Water
Column) or 6.35 oz. of outlet pressure to the trailer
system. The second stage is adjustable and will need
to be adjusted for precise operation. We suggest this
normal maintenance procedure be performed once
per year. Have only an authorized technician make
any adjustments.

WARNING:
always be installed with the diaphragm vent facing downward. Regulators that are
not in a 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.
Be sure your LP gas regulator is protected from moisture. If water enters the vent in the regulator, it
may freeze the pressure controlling diaphragm in the open position so that the tank pressure is
applied to the appliances - a hazardous condition. Be sure to carefully read the instructions given by
the manufacturer of the regulator.
