Electric Operation
1. For gas operation refer to Pilot Operation or Electronic
Ignition Operation section.
2. For electrical operation, use the switch at the rear of
water heater.
3. Completely fill tank with water.
4. Turn switch (Fig. 5-10B) located at the rear of the water
heaters to the “ON” position.
NOTE:
Turning the power on in the heater with little or
no water covering the heating element may burn
out the element and void the warranty.
5. Check for proper operation. Water temperature should
be approximately 140°F (60°C).
6. If the manual reset high temperature limit switch should
operate, reset the switch (Fig. 5-10A) by depressing the
button. Use a pencil or other nonmetallic object to
depress the rest button. If the malfunction repeats,
contact an authorized Atwood Service Center or Atwood
Service Department.
PRESSURE TEMPERATURE RELIEF VALVE
WARNING: Do not plug the pressure-temperature relief valve under any
circumstances.
When cold water is heated in the tank, the pressure will rise. For this reason, a relief valve
(Fig. 5-11) is required for safety in all water heaters rated at 125°. It is normal for this
valve to release a small quantity of water during the heating cycle. Open the hot water
faucet to release pressure which will reduce the dripping from the relief valve.
Flushing Instructions
If your travel trailer is used frequently, or taken to different areas that use various types
of water, it is recommended that the water heater be flushed periodically throughout the
year to prolong the life of the inner tank. The following procedure summarizes the steps
necessary for flushing the water heater inner tank.
CAUTION: Turn off the water heater and allow time for the water to cool before
removing the drain plug to flush the tank.
1. Turn off your main water supply (pump or water hook-up source).
2. Drain the water heater inner tank. Approximately two quarts of water will remain in
the bottom of the tank. This water contains a great deal of the harmful corrosive
material that has accumulated in the tank.
3. Flush tank with air pressure or fresh water to remove the remaining water.
Air Pressure: Air pressure may be applied through the inlet or outlet valve located
on the rear of the tank or the relief valve (Fig. 5-11) located on the front of the unit.
If the relief valve is used, remove the relief valve prior to flushing and insert air
pressure through the relief valve support flange.
