Water Heater Conversion 3E To 4E & 9E 10E - Atwood Pilot 6 Gallon User Manual

A Division of Dura Automotive Systems
ENGLISH,
The gas/electric water heater (Models 4-E & 10-E) replaced all
previous combination gas/electric water heaters. Models 3-E &
9-E and before operate on DC for the gas side and AC for the
electric side.
These older models operate with two separate switches, one DC
and one AC. The gas switch has DC voltage coming into the
switch and from the switch to the water heater. There is a
separate switch used for the electric portion of the water heater.
This switch will have AC power coming into the switch and AC
going out of the switch to the electric part of the water heater.
The 3-E and 9-E's are no longer available, if an entire water heater
must be replaced it will be replaced with the new 4-E or 10-E.
There are no changes in the physical dimensions, but a wiring change
will be required.
With the new water heater you will receive a new 12 volt control
switch for both gas and electric.
The separate gas and electric switches will be replaced by this
(one) combo switch on current production.

LOCATION OF COMBO SWITCH
Find the most convenient location for the new switch. It should
be close to the DC voltage source that will control the switch.
This may be where the AC switch was originally located.
Remember that you will have to connect DC positive and
negative into this switch. There will also be four wires from the
water heater that must attach to the switch.
If your original system was controlled through a central monitor
panel, and you prefer to use this system, you will have to contact
the manufacture of the unit for monitor panel wiring instructions.
