Regulator
The regulator is the heart of your LP gas system,
with internal moving parts. Its function is to re-
duce the high and varied pressure from the LP
container to safe and consistent low operating
pressure. The inlet is the first stage and reduces
container 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 coach 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 and competent
technician make any adjustments.
WARNING: LP gas regulators must always be installed with the diaphragm
vent facing downward. Regulators that are not in 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 road spray. If water enters the vent in the
regulator, it may freeze the pressure controlling diaphragm in the open position so that
the container pressure is applied to the appliances – a hazardous condition. Be sure to
carefully read the instructions given by the manufacturer of the regulator.
Operation
After the camper is completely set up and you are prepared for camping enjoyment,
follow these steps for LP gas operation.
1. Close ALL burner valves, controls and pilot light valves.
2. Open main valve on LP container slowly to avoid a fast rush through the excess
flow valve causing "gas freeze." Should you experience a gas "freeze-up," close the
main valve and wait 15 minutes before trying again.
3. Listen carefully as gas begins to flow. If "hissing" is heard for more than one or two
seconds, close valve and search for leak.
4. Light appliances as needed and directed in the appliance chapter.
WARNING: Portable fuel-burning equipment, including wood and charcoal
grills and stoves, shall not be used inside the recreation vehicle. The use of this
equipment inside the recreation vehicle may cause fires or asphyxiation.
