SCALDING INJURY

Setting temperature control dial at a higher position will produce exces-

•

sively hot water.

The temperature knob or lever is factory adjusted to its lowest dial set-

ting. 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 Atwood 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. 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 pos-

sibility 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 ther-

mal 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 con-

tact the cutoff, resulting in a melting of the fuse element incorporat-

ed in the thermal cutoff. In order to restore power and proper oper-

ation of the water heater, the obstruction must be removed and the

thermal cutoff must be replaced.
