hot water system. If hydrogen is present, you
probably will hear an unusual sound such as
air escaping through the pipe as the water
begins to flow. Hydrogen gas may be present
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).
HYDROGEN GAS
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.
Odor from the hot water system
Many water supplies
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
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 RV
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
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

contain sufficient
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
If you smell propane gas then STOP! and
follow the procedures listed in Sec. 3
Propane System before attempting to
operate the water heater.
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 RV is to be stored over the winter
months, the water heater must be drained to
prevent damage from

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.
