WARNING
EXPLOSION
FOR REPLACEMENT PARTS:
•Do not install anything less than a combination
•Installation must conform with local codes or in the absence of local codes, American National Standard for Recreational Vehicles, ANSI A119.2/NFPA 50IC.
•If you use an external electrical source, ground this unit in accordance with National Electrical Code ANSI/NFPA70. All wiring must comply with the applicable electrical codes.
•Use electrical metallic tubing, flexible metal conduit, metal clad cable, or
CAUTION
PRODUCT DAMAGE
•Label all wires before disconnecting when servicing controls.
•Verify proper operation after servicing.
•When using Romex® with a bare earth ground, take care to position ground wire so it does not contact the heating element terminals.
OPERATION
1.Check to be sure water completely fills the water heater tank.
2.Locate remote water heater operation switch. (see vehicle owners manual for location of switch).
3.Turn remote switch to ON.

WINTERIZING (FLUSHING) INSTRUCTIONS
To insure the best performance of your water heater and add to the life of the tank, periodically drain and flush the water heater tank. Before long term storage or freezing weather drain and flush the tank.
1.Turn off main water supply (the pump or water supply (the pump or water hook up source).
2.Drain Water Heater Tank by removing the drain plug. If the water flows sporadically or trickles instead of a steady stream of water, we recommend the following action; first open the Pressure Temperature Relief Valve to allow air into the tank and secondly, take a small gauge wire or coat hanger and poke through the drain opening to eliminate any obstructions.
3.After draining the tank, because of the placement of the Drain Plug, approximately two quarts of water will remain in the tank. This water contains most of the harmful corrosive particles. To remove these harmful corrosive particles flush the tank with either air or water. Whether using air or water pressure, it may be applied through the inlet or outlet on the rear of the tank or the Pressure Temperature Relief Valve. (If using the Pressure Temperature Relief Valve the Support Flange must be removed). The pressure will force out the remaining water and the corrosive particles.
If you use water pressure, pump fresh water into the tank with the assistance of the

water, as it is heated in the closed water system of a recreation vehicle, the Pressure Temperature Relief Valve will sometimes drip. The Atwood water heater tank is designed with an internal air gap at the top of the tank to reduce the possibility of dripping. In time, the expanding water will absorb this air and it must be restored.

TO REPLACE THE AIR GAP FOLLOW THESE STEPS:
1.Turn off main water supply (the pump or water hook up source).
2.Let water cool or let run until cool.
3.Open the hot water faucet closest to the water heater.
4.Pull handle of pressure temperature relief valve straight out and allow water to flow until it stops.
