PROPANE REGULATOR
Your camper is equipped with a two-stage regulator that reduces pressure
from the LP tank to the piping system. The rst stage drops pressure
to 10-13 lbs. pressure. The second stage drops pressure to the 6.35 oz.
pressure (11” Water Column or ½ PSI) needed to operate appliances
properly. Pressures that are too high or too low will cause safety hazards
and affect overall appliance performance. Consult your dealer or a
qualied service professional to have the regulator adjusted with a
properly calibrated manometer. Be sure to follow the propane regulator
manufacturer’s instructions included in your owner’s packet for proper
operation, maintenance and use.
PROPANE SYSTEM MAINTENANCE
It is possible for the propane regulator to “freeze” in certain climate
conditions due to the properties of propane and the dynamics of
pressure change inside the regulator. In case of freezing, use an
incandescent light bulb or heated blanket to warm the regulator and
then have the system purged. Consider purchasing a propane regulator
cover, available online and at most major hardware stores, to protect your
regulator and prevent freezing.
Environment, usage and time can deteriorate parts in the propane piping
system. Inspect the piping system before each camping season. Look for
cracks, loss of exibility and corrosion. If parts need replaced, consult your
nuCamp dealer for proper parts of the same type and rating.
PROPANE USAGE
Propane usage uctuates, so there is no real way to accurately measure
propane usage. This uctuation is due to varying usages of appliances.
Propane usage can be measured to some degree of accuracy by
understanding BTUs of appliances and the capacity of LP tanks. A
standard 20 lb. LP tank contains approximately 430,270 BTUs of propane
gas while a standard 30 lb. LP tank contains approximately 645,405 BTUs.

120V AC shore power is powerful enough
to kill you. Always use a grounded shore
power connection and never remove
the “third” ground prong from your
shore power cord. Both reverse polarity
or improper grounding in the 120V AC
supply outlet can cause serious injury or
death. Do not connect the shore power
cord if either or both are present.

ELECTRICAL SAFETY & INFORMATION
Two electrical systems are outtted on your camper – the primary 12V
DC and 120V AC shore power. These electrical systems are engineered
to efciently provide power to the various appliances and features in the
camper. All designs, components and wiring methods of the electrical
systems conform to federal and RVIA installation requirements at the time
of production.
Electrical Safety and Information:
• Aftermarket changes made to the electrical system can result
in electrical and re hazards. Never add appliances, features or
other unapproved changes to the electrical system without the
assistance of a qualied technician.
• Electricity can pose a hazard if you do not understand how the
electrical system works. Only qualied electrical technicians should
service the electrical system and make changes to it in any way.
• Install a surge protector in the supplying 120V AC outlet before
plugging in your shore power cord. This will protect your camper’s
electrical system from damage caused by power surges.
• ALWAYS disconnect electrical power at the source when you work
with the electrical system.
• Remove rings, wristbands or other metal objects when working with
the electrical system.
• Before you connect your shore power cord to an external supply,
test the outlet with an outlet-testing device that indicates whether
reverse polarity or an open ground is present in the outlet. If the
outlet- testing device indicates either of those conditions, have the
outlet repaired. Outlet testing devices are available from your
dealer or an RV/camping supply center.
• ALWAYS fully extend the power cord. Do not coil up the cord.
Excessive heat build-up can cause the wire coating to melt, thereby
becoming exposed and leading to an electrical hazard.
120V AC SHORE POWER
When connected to an external 120V outlet or generator via the 120V
shore power cord, your camper will be supplied with power. The electrical
system will be grounded via shore power if there is no open ground in the
supplying outlet or generator. The negative terminal on your battery serves
as a ground to your electrical system when shore power is disconnected.
The 120V electrical system provides power for:
• Air Conditioner
• Microwave
• Refrigerator (12V DC via Converter)
• Alde
®
System (Plus LP)
• Power Center/ Converter
• 120V Receptacles
An odor like garlic can occur when the LP
bottle is almost empty. The smell will go
away when the bottle is relled. If the
odor persists after the bottle is relled,
turn off all gas valves and have your
system inspected by a nuCamp dealer or
other qualied service technician.
