Rheem XE40M06ST45U1 Fury Residential Electric Water Heater
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WATER TEMPERATURE SETTING
- Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater’s thermostat. Water temperatures above 125°F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below. This label is also located on the water heater near the thermostat access panel.
- Time/Temperature Relationship in Scalds
- The temperature of the water in the heater is regulated by the adjustable surface-mounted thermostat(s) located behind the jacket access panel(s). Dual-element heaters have two thermostats. To comply with safety regulations the thermostat(s) were set at 120°F before the water heater was shipped from the factory.
- The illustration at the left shows the temperature adjustment dial used for setting the water temperature.
- Refer to the Operating Instructions in this manual for detailed instructions in how to adjust the thermostat(s).
Installing the water heater.
Location
- Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long uninsulated hot water lines can waste energy and water. Place the water heater in such a manner that the thermostat and element access panels can be removed to permit inspection and servicing such as the removal of elements or checking controls
- NOTICE: Auxiliary catch pan MUST conform to local codes. Catch Pan Kits are available from the store where the water heater was purchased, or any water heater distributor.
Thermal Expansion
- Determine if a check valve exists in the inlet water line. Check with your local water utility. It may have been installed in the cold water line as a separate backflow preventer, or it may be part of a pressure-reducing valve, water meter, or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system”. A cold water inlet line with no check valve or backflow prevention device is referred to as an “open” water system.
- As water is heated, it expands in volume and creates an increase in the pressure within the water system. This action is referred to as “thermal expansion”. In an “open” water system, expanding water that exceeds the capacity of the water heater flows back into the city main where the pressure is easily dissipated.
- A “closed water system”, however, prevents the expanding water from flowing back into the main supply line, and the result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater and system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve, and possibly the heater itself. Replacing the relief valve will not correct the problem
Water Supply Connections
- Refer to the illustration below for a suggested typical installation. The installation of unions or flexible copper connectors is recommended on the hot and cold water connections so that the water heater may be easily disconnected for servicing if necessary. The HOT and COLD water connections are clearly marked and are 3/4″ NPT on all models. Install a shut-off valve in the cold water line near the water heater
Typical Installation
To Fill the Water Heater
- Make certain the drain valve is completely closed. Open the shut-off valve in the cold water supply line. Open each hot water faucet slowly to allow the air to vent from the water heater and piping.
- Condensation
- Condensation can form on the tank when it is first filled with water. Condensation might also occur with a heavy water draw and very cold inlet water temperature. This condition is not unusual and will disappear after the water becomes heated. If, however, the condensation continues, examine the piping and fittings for possible leaks. Additional information on this subject may be found at www.rheem.com under “Library”.
Electrical Connections
- A separate branch circuit with copper conductors, an overcurrent protective device, and suitable disconnecting means must be provided by a qualified electrician
The branch circuit wiring should include either:
- A metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with fittings approved for the purpose.
- Non-metallic sheathed cable, metallic conduit or metallic sheathed cable not approved for use as the ground conductor shall include a separate conductor for grounding. It should be attached to the ground terminals of the water heater and the electrical distribution box.
Hot and Cold Pipe Insulation Installation
- For increased energy efficiency, some water heaters have been supplied with two 24” sections of pipe insulation.
- Please install the insulation, according to the illustrations above, that best meets your requirements

Operating the water heater
If adjustment is necessary…
- Turn off the power to the water heater.
- Remove the jacket access panel(s) and insulation exposing the thermostat(s). The thermostat protective cover(s) should not be removed.
- Using a small screwdriver, set the thermostat(s) dial pointer(s) to the desired temperature.
- Replace the insulation and jacket access panel(s). Turn on the power to the water heater.
Routine Preventative Maintenance
- Properly maintained, your water heater will provide years of dependable trouble-free service. It is suggested that a routine preventive maintenance program be established and followed by the user.
- It is further recommended that a periodic inspection of the operating controls, heating element and wiring should be made by service personnel qualified in
electric appliance repair. - Most electrical appliances, even when new, make some sound when in operation. If the hissing or singing sound level increases excessively, the electric heating
element may require cleaning. Contact a qualified installer or plumbing contractor to inspect. - At least once a year, lift and release the lever handle on the temperature pressure relief valve, located near the top of the water heater, to make certain the valve
operates freely. Allow several gallons to flush through the discharge line to an open drain.
Replacement Parts
Instructions For Placing a Parts Order Address parts orders to the distributor or store where the heater was purchased. All parts orders should include:
- The model and serial number of the water heater from the rating plate.
- Specify voltage and wattage as marked on the rating plate.
