Wiring Diagram For Atwood Water Heater

Atwood Water Heaters are an essential part of any recreational vehicle, providing hot water for showering, cleaning, and general household needs. It is important to understand the technical requirements of your Atwood water heater in order to ensure its safe and effective use. This article will cover the voltage requirement, number of heating elements, maximum temperature setting, purpose of the pressure relief valve, how to reset the high limit switch, what the bypass valve is used for, how long it takes for the water heater to heat up, what size propane tank is needed, and if it is safe to operate the water heater while in motion.

Voltage Requirement

The Atwood water heater requires a 12-volt DC power source to operate. This can be provided by the batteries in your RV, or it may require you to plug the heater into your vehicle's battery. Depending on the model of your water heater, you may need to install an optional converter kit in order to operate the heater from a 110-volt AC power supply.

Heating Elements

Atwood water heaters have either one or two heating elements, depending on the model. The single element models have a 12-volt DC element, while the dual element models have both a 12-volt DC element and a 240-volt AC element. The dual element models are more efficient, as they can draw more power from the 240-volt AC source.

Maximum Temperature Setting

The maximum temperature setting on the Atwood water heater is typically set to 140 degrees Fahrenheit. This temperature setting should not be exceeded, as it could cause serious damage to the heater.

Pressure Relief Valve

The pressure relief valve is designed to prevent excessive pressure buildup within the water heater. If the pressure rises to an unsafe level, the valve will open and release any excess pressure. It is important to check the valve periodically to make sure it is functioning correctly.

Resetting High Limit Switch

To reset the high limit switch on the Atwood water heater, you should first shut off the power to the heater. Then unscrew the access panel and locate the switch. Turn the knob clockwise to reset the switch. Make sure the switch contacts are making contact with each other before turning the power back on.

Bypass Valve

The bypass valve is used to regulate the flow of water through the tank. When the valve is closed, the flow of water is stopped and no water will enter the tank. When the valve is opened, the flow of water is allowed again. This allows you to conserve water when the water heater is not in use.

Heating Up Time

The amount of time it takes for the water heater to heat up will depend on the size of the water heater, the amount of hot water being used, and the temperature setting. On average, it takes about 10 minutes for the water heater to reach the set temperature.

Propane Tank Size

The size of the propane tank you will need for your Atwood water heater depends on the size of the water heater and your usage. Generally, a 20-pound propane tank will provide enough fuel for a 10-gallon water heater for up to two weeks of operation.

Operating While in Motion

It is not recommended to operate the Atwood water heater while the vehicle is in motion, as this can cause the water heater to malfunction or even cause a fire. Before starting a journey, it is best to turn off the water heater completely and wait until you have reached your destination before turning it back on.

Understanding the technical requirements of your Atwood water heater is essential for its safe and effective use. Knowing the voltage requirement, number of heating elements, maximum temperature setting, purpose of the pressure relief valve, how to reset the high limit switch, what the bypass valve is used for, how long it takes for the water heater to heat up, what size propane tank is needed, and if it is safe to operate the water heater while in motion can help you keep your water heater running smoothly and safely.
