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.

ELECTRONIC IGNITION OPERATION
1. Refer to WIRING DIAGRAM. Place remote switch in ON position.
2. If remote switch light stays on longer than 15 seconds, place
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 Dometic Service Center.

controls.
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 any aftermarket heating element devices may also result in
damage to components or water heater. Dometic'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
and 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.
• Presence of soot indicates the need to adjust flue.
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. The thermal cutoff is a device installed in the 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, such as described above 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.
