Draining and winterization
If the RV 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.
Water heater bypass
Use the factory installed water heater bypass, available in most floor plans, to
avoid filling the entire water heater with RV antifreeze. (See Outside Convenience
Center for details on using the bypass system).
Water heater switch (if so equipped)
The "propane GAS" water heater switch enables propane operation of the water
heater. The "ELECTRIC" water heater switch enables electric operation of the
water heater
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. Refer to
the water heater manufacturer’s owners manual for details on eliminating the odor
from sulfur water. Odor from sulfur water is not a service problem.
High altitude deration
Operation of the water heater at high altitudes may require derating. If the water
heater is not properly derated, lack of sufficient oxygen for combustion may
produce improper burner operation. Pilot outage caused by burner lift-off or
sooting from a yellow burner may occur, indicating the possibility of carbon
monoxide.
You may also notice a lack of efficiency in heating the water because of
incomplete combustion of the burner at these higher altitudes.
Consult with the local propane company, your dealer or the water heater
manufacturer for proper derating of the water heater. Change out of the orifice
(derating) should be done by the dealer or a qualified service agency.
NOTE
: It is important that once the RV has returned to lower elevation (below
4500 feet) any high altitude deration or other adjustments be reversed for proper
operation of the water heater.
Pressure & temperature relief valve
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 manufacturer’s
manual); If the weeping persists, consult your dealer or a service agency
authorized by the water heater manufacturer.
