SCALDING INJURY
Setting temperature control dial at a higher position will produce

excessively hot water.
The temperature knob or lever is factory adjusted to its lowest dial
setting. We recommended the mid-point position between warm and
hot, as noted above. This will provide for energy efficient operation
and sufficient hot water. Valves for reducing point of use temperature
by mixing cold and hot water are available. Consult a licensed plumber
or local plumbing authority.

remote switch in OFF position and wait 5 minutes.
3. Repeat step one.
4. For complete shut-down and before servicing:
a. Place remote switch in OFF position.
b. Remove red wire from left hand terminal of ECO switch (ECO to
valve).
5. If heater fails to operate due to high water temperature, a lockout
condition occurs (indicator light on). After water cools, reset switch
in OFF position for at least 30 seconds, then turn to ON position.
6. If a lockout condition persists contact an Atwood Service Center.

lockout and the red lockout lamp will illuminate. If the thermostat fails,
the ECO will also lockout the unit, requiring resetting. Determine the
reason for no ignition, correct it, and reset the gas ignition sequence
by turning the switch off, then on.

ignite, the gas mode will lockout, but the lockout lamp will not
illuminate since the electric mode is still operational. Should you notice
slow recovery, indicating the gas is not working, turn the electric
switch off. The lamp will then illuminate indicating a lockout has
occurred on the gas side. Correct the problem and turn the switches
back on.

Use of Aftermarket heating elements can lead to an out of control

heating of water tank and a catastrophic wet side explosion.
The use of manufacturer's aftermarket heating element devices may
also result in damage to components or water heater. Atwood's written
warranty states - "failure or damage resulting from any alteration to
our water heater is the owner's responsibility". Any alteration, like the
addition of an aftermarket heating element device, will void the warranty.
GENERAL INFORMATION
• LP and Water system must be turned on.
• Have gas pressure tested periodically. Should be set at 11 inches of
water column with three appliances running.
• Drain water heater at regular intervals (at least one time during the
year).
• Drain water heater before storing RV for the winter or when the
possibility of freezing exists.
• Keep vent and combustion air grill clear of any obstructions.
• Periodically, compare flame of main and pilot burners with
main burner adjustments in
• When water heater is not in use set temperature control lever (White
Rogers) or dial (Robertshaw) to lowest possible position. This will
reduce the effects of low outdoor temperatures on calibration of
temperature control mechanism.
ELECTRONIC IGNITION MAINTENANCE
• The water heater comes factory-equipped with a fused circuit board,
which will protect the circuit board from wiring shorts. If the fuse
should activate, the water heater will not operate. Before replacing
the fuse, check for a short external to the board. Once the short is
corrected, replace the 2 amp fuse with a mini ATO style fuse. Do not
install a fuse larger than 3 amps.
• If the fuse is good and the unit is inoperative, check for excessively
high voltage to the unit (more than 14 volts).
• If the previous two steps did not solve the problem, check the
thermal cut-off (
power supply line. This device will shut off electrical power and stop
heater operation when activated. For example, if an obstruction
within the flue tube should occur, as described in the Preventative
Maintenance section, the burner flame/heat may contact the cutoff,
resulting in a melting of the fuse element incorporated in the
thermal cutoff. In order to restore power and proper operation of the
water heater, the obstruction must be removed and the thermal
cutoff must be replaced.
PREVENTATIVE MAINTENANCE
Spiders, mud wasps, and other insects can build nests in the burner
tube. This will cause poor combustion, delayed ignition or ignition
outside combustion tube. Listen for a change in burner sounds or in
flame appearance from a hard blue flame to a soft lazy flame or one
that is very yellow. These are indications of an obstruction in burner
tube (
4-C). Inspect and clean on a regular basis.
