Jayco 2016 Melbourne Owner's Manual page 111

The DSI water heater is designed to heat water quickly and efficiently. The water heater
manufacturer has preset the sensing limit to maintain the water temperature when the water
heater is activated. The thermostat on your water heater is not adjustable. It is a temperature
sensing limit designed to maintain a water temperature of 130°F (54°C).
The water heater does not have a pilot. It is equipped with an ignition device which
automatically lights the burner. Do not try to light the burner by hand.
Operating instructions
1. Turn OFF all electric power to the water heater.
2. Turn OFF the propane supply.
Wait five minutes for the propane to clear the area. If you smell propane STOP!
3.
Follow the safety instructions listed in the manufacturer's owner's manual. If you do
not smell propane, go to the next step.
4. Turn ON the propane supply.
5. Turn ON electrical power to the water heater.
6. Turn the switch to the "ON" position. If the burner does not light, the system will
automatically attempt two more tries for ignition before lock-out occurs. NOTE: Each
ignition cycle will have a 15 second purge before spark cycle if system is a three try
system.
7. If lock-out occurs before the main burner lights, turn the water heater control switch
to OFF, wait five seconds and turn the switch to the ON position. This will restart the
ignition cycle.
8. The first start-up of the heater may require several ignition cycles before all the air is
purged form the propane lines.
If the burner will not come on, the following items should be checked before calling a
service person:
1. See if the switch is turned OFF.
2. Check to make sure the propane supply to the water heater is not empty or turned OFF.
3. Check to see if the reset button on the water heater ECO is tripped.
Water heater bypass (If So Equipped)
Your motor home may be equipped with a water heater bypass. This three-valve system
is located at either the water heater, or on the system panel depending on your model. For
detailed information see the Water Heater Bypass section
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
owner's manual for details on eliminating the odor from sulfur water. Odor from sulfur
water is not a service problem.
Do not replace anode rod or any other component with an accessory part that
is not authorized by the water heater manufacturer, such as an "add-on electric
heating element. Such items are not approved to be installed and could create
an unsafe condition and will void all warranties
