PLUMBING SYSTEMS

even after water has been drained from the
tank. Open the sink faucet at the sink and
allow system to vent for five to ten minutes (or
as needed).

Atwood gas/electric water heaters built for
RPTIA have manual propane shutoff valves.

Odor from the hot water system

Many water supplies contain sufficient
amounts of sulfur to produce an odor, often
called “sulfur water.” Sulfur water can be
caused by a chemical action or by bacteria.
Generally, sulfur water is not harmful, only
unpleasant to smell. To eliminate sulfur water
(or bacteria) sanitize the water heater. Odor
from sulfur water is not a service problem.

High altitude deration
(Atwood water heater)

Operation of the water heater at high altitudes
may require derating. Consult with your local
propane gas company, dealer or the water
heater OEM for proper derating of the water
heater. Change out of the orifice (derating)
should be done by your Dealer or a service
agency authorized by the water heater
manufacturer. It is important that once the
park trailer has returned to lower elevation
any high altitude deration or other
adjustments be reversed for proper operation
of the water heater.

Pressure & temperature relief valve
(Atwood water heater)

When cold water is heated in the water heater
tank, the water pressure will rise. For this
reason, a pressure and temperature (P&T)
relief valve is required for safety in all water
heaters. It is normal for the P&T relief valve to
release a small quantity of water during the
heating cycle and does not indicate a
defective P&T relief valve. One way to reduce
the frequency of the water weeping or

dripping from the P&T relief valve is to
maintain an air pocket at the top of the water
heater. This air pocket will form in the tank by
design; however, it will be reduced over time
by the everyday use of your water heater
(refer to the OEM manual); If the weeping
persists, consult your dealer or a service
agency authorized by the water heater
manufacturer.

Operating instructions

Fig. 7.4 Electric water heater label

STOP!

Read the safety and operating

information provided in the OEM operator’s
manual before attempting to activate the
water heater. Make sure the water heater is
filled with water before use; momentary
operation of the water heater without water in
it can be detrimental.

Draining and winterization

If the park trailer is to be stored over the
winter months, the water heater must be
drained to prevent damage from freezing. It is
recommended the water heater be drained
and bypassed during the winterization
process particularly if introducing RV
antifreeze into the plumbing system.

Atwood gas/electric water heater

: Follow the

OEM supplied instructions to drain.

Rheem electric water heater

: Drain by

opening the low point valves.

HYDROGEN GAS IS EXTREMELY
FLAMMABLE.

Do not smoke or have any

open flame near the open faucet. On DSI
water heater models make sure the interior
control switch is OFF during the above
listed procedure.

If you smell propane gas then

STOP!
