DO NOT APPLY 110 VAC POWER to or LIGHT the water heater until after the water
heater is filled with water and the water lines and heater tank are purged of any
trapped air. Failure to do so will damage the water heater and may cause additional
Proper and safe operation of the water heater requires that all safety information provided in the owner's
manual be read and understood before placing the water heater in service. Take the time to become
familiar with this manual (provided in the Owner's Information Package).
The water heater is designed for operation either with LP gas or 120-volt AC electricity. Both modes of
operation are now presented.
LP Gas – Electronic Ignition Operation (6-Gallon Models)
1. Turn the remote switch to the "on" position.
2. If the remote-switch light stays "on" longer than 15 seconds, turn the remote switch to the "off"
position and wait 5 minutes.
3. Repeat Step One.
4. (For 6-Gallon Models only): For complete shut-down and also before any servicing:
a. Turn the remote switch to the "off" position.
b. Remove the red wire from the left-hand terminal of the ECO switch (ECO to valve).
5. If the water heater fails to operate because of high water temperature, the heater will go into a lockout
condition (indicator light "on"). When the water eventually cools, reset the system by turning the
switch to the "off" position for at least 30 seconds, and then turn the switch back "on."
6. If a lockout condition persists, contact your authorized dealer.
120-Volt AC Electrical Operation
1. For electrical operation (if the motor-home electrical service is rated greater than 30 Amperes), use the
power switch on the water heater; depending on the particular model, that switch may be located either
at the front or at the rear of the water heater.
2. Completely fill the water heater with water and purge the hot-water lines of any trapped air.
3. Turn the power switch located on the water heater "on." NOTE: Turning the power "on" to the water heater
without having previously covered the water-heating element with water may burn out the element and void
the warranty.
4. After a while, check the water heater for proper operation; the water temperature should be approximately
140°F (60°C).
