Read the safety and operating information
provided in the manufacturer’s manual before
attempting to activate the water heater. Make
sure the water heater is filled with water
before use; even momentary operation of the
water heater without water in it may result in
damage to the tank
and/or controls.
Always
open both the hot and cold water
faucets when filling the fresh water tank to
allow air pockets to be forced out of the water
heater.
Operating instructions
Read the safety and operating information
provided in the manufacturer’s user guide
before attempting to activate the water heater.
Make sure the water heater is filled with water
before use; even momentary operation of the
water heater without water in it may result in
damage to the tank
and/or controls.
Hydrogen gas may result if you have not
used the water heater for two weeks or
more.
HYDROGEN GAS IS EXTREMELY
FLAMMABLE.
To reduce the risk of injury
under these conditions, open the hot water
faucet for several minutes at the kitchen
sink before you use any electrical
appliance connected to the hot water
system. If hydrogen is present, you may
hear what sounds like air escaping through
the pipe as the water begins to flow.
Hydrogen gas may be present even after
water has been drained from the water
heater tank. Open the faucet at the sink
and allow the system to vent for five to ten
minutes. Do not smoke or have any open
flame near the open faucet while venting.
On DSI water heater models, make sure
the switch is OFF.
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.
Fig. 7.4 Water heater bypass
To bypass the water heater close valves A
and B, and open the mixer valve (valve C).
For normal camping usage of the water
heater, reverse these instructions.
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
If you smell propane gas then
STOP!
and
follow the procedures listed in
Sec. 6
Propane System
before attempting to
operate the water heater.
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.
