Engine Heat Exchange System / Aftermarket Heating Elements - Atwood Pilot 6 Gallon User Manual

Custom er supplied SAE 053 A type
Heat Exchanger
The engine heat exchange system allows a motor home to heat the water while traveling. This convenient
option allows you to arrive at your destination with hot water. Operating a pilot or electronic water heater on
gas while in transit is a dangerous practice.
This system consists of a U-shaped aluminum tube that is attached to the outside of the tank with welds. SAE
hoses are attached to both ends of this tube and are spliced into the engine coolant system.
When the engine is running, the hot coolant flows past the tank through this tube and by means of heat
transfer through the welds, heating the water. The design of this system will not allow the water to reach a
boiling point.
• Aftermarket heating elements can lack critical safety controls.
• Use of these devices can lead to an out of control heating of water tank and a
catastrophic wet side explosion.
YOU DO NOT NEED AN AFTERMARKET HEATING ELEMENT ON AN ATWOOD WATER HEATER
ELEMENT DEVICES MAY ALSO RESULT IN DAMAGE TO COMPONENTS OR WATER HEATER
- "failure or damage resulting from any alteration to our water heater is the owner's responsibility".

ALTERATION SUCH AS THE ADDITION OF AN AFTERMARKET HEATING ELEMENT DEVICE
• Temperatures produced by these heating elements
can exceed the 190˚F. limit of the ECO on pilot model
gas control valves. This gas control valve contains a
one-shot ECO. When this ECO blows, the control is
completely non-functional and must be replaced.

THE USE OF AFTERMARKET HEATING
. Atwood's written warranty states
,
WILL VOID THE WARRANTY
• When Aftermarket heating elements are inserted
into the drain plug, customers are more prone not
to flush their tanks. Not flushing the tank
accelerates tank corrosion on both our pilot and
electronic ignition water heaters creating a situation
where the tank may have to be replaced.
