AFTERMARKET WATER HEATING ELEMENT DEVICES
I
WARNING: EXPLOSION / BURN INJURY
• DO NOT alter water heater, it will void warranty.
• DO NOT USE Aftermarket heating elements, they can lack critical safety
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 a manufacturer's after market 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 this 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 figure
6-3 and main burner adjustments in HOW TO OPERATE YOUR WATER HEATER.
• 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. The thermal
cut-off 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 below in the Preventative maintenance section, the burner
flame/heat may contact the cut-off, resulting in a melting of the fuse element incorporated in
the thermal cut-off. In order to restore power and proper operation of the water heater, the
obstruction must be removed and the thermal cut-off must be replaced.
