Electric Operation
1. For gas operation refer to Pilot Operation or Electronic Ignition Operation section.
2. For electrical operation, use the switch inside the mini-motorhome in the utility
panel.
3. Completely fill tank with water.
4. Turn switch (Fig. 5-7) located in the mini-motorhome 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. 5-8) 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.
When cold water is heated in the tank, the pressure will rise. For this reason, a relief
valve (Fig. 5-9) is required for safety in all water heaters, rated at 125° (52° C). It is
normal for this valve to release a small quantity of water during the heating cycle.
Opening a faucet on the hot side will release pressure reducing relief valve dripping.

Flushing Instructions
The Atwood water heater is recommended for recreation vehicle use. If your RV 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.
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 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.
