LOCATING THE WATER HEATER Locate the water heater where any leakage from the relief valve, related piping, tank, or connections will not result in damage to surrounding areas or lower floors of the building.
Incorrectly-sized expansion tank 5. All piping should be insulated. Additionally, place the water heater so that the drain, controls, and inlets/outlets are easily accessible. If you do not provide the minimum clearances shown, it might not be possible to service the heater without removing it from the space. NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to make note of the water heater model and serial number. 6.
Other methods of controlling thermal expansion are available. Check with the local water utility to determine if a check valve exists in the cold water inlet line. Contact your installing contractor, water supplier, or plumbing inspector for additional information regarding thermal expansion. C. CONDENSATION Condensation can form on the water heater when it is first filled with water, and may also occur with a heavy water draw and very cold inlet water temperature.
Do not thread a cap or plug into the relief valve under any circumstances! Explosion and property damage, serious injury, or death may result. F. FILLING THE HEATER When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heater is turned on. Failure to ensure the water heater is full before turning it on will result in damage to the water heater, and could result in property damage.

The installer is responsible for all equipment and detailing required by local codes. NOTE: Heat traps are optional. PART 4 – HEATER WIRING Tank must be full of water before power is turned on. Heating elements will be damaged if energized for even a short time while tank is dry. Failures due to “dry-firing” are NOT covered by warranty.
Figure 5 - Wiring Detail Be sure to ground the water heater. The preferred way to ground is with rigid metal conduit between the main panel and the water heater junction box with approved end fittings (check codes on the use of flexible conduit). If making a separate ground, a green ground wire is provided in the water heater junction box. Replace the junction box cover and insulation after you have made the wiring connections.
RELIEF VALVE YES NO YES NO Temperature and Pressure Relief Valve properly installed and discharge line run to open drain Discharge line protected from freezing WIRING Power supply voltage agrees with water heater rating plate Branch circuit wire and fusing or circuit breaker of proper size Electrical connections tight and unit properly grounded Table 4 – Installation Checklist PART 6 – OPERATING THE HEATER Tank must be full of water before power is turned on.
STEP #5 – Replace the insulation. Failure to replace insulation could result in property damage, severe personal injury, or death. STEP #6 – Reattach the access cover with the two screws. STEP #7 – Restore power by replacing the fuse or turning on the circuit breaker. STEP #8 a. After resetting the ECO, ensure the water heater is operating properly before leaving the installation. b. After adjusting the water temperature, allow the water heater enough time to heat the water to temperature.
STEP #5 – Put a small amount of NSF approved lubricant and sealant on the O-Ring. STEP #6 – Screw the element clockwise into tank, and tighten with the 1 ½” socket wrench or element tool. Be sure O-ring seats properly. NOTE: REPEAT STEPS 3 – 6 AS NECESSARY FOR MULTIPLE ELEMENTS Figure 7 – Heating Element Detail STEP #6 – Open the main cold water inlet. If the water heater has been isolated from the system, open the valves. Refill the tank with cold water.
Water drained from the water heater may be scalding hot. Take care to avoid scalding. Wear gloves and safety glasses, and direct water to a safe drainage location. It is recommended to turn power off to the water heater and run the water at a hot faucet until it cools BEFORE draining water from the heater. Failure to comply with this warning could result in substantial property damage, severe personal injury, or death due to scalds. After flushing until water runs clear, operation is complete.
6. Turn power supply off to the water heater. Open the drain valve and drain a few gallons of water from the tank to clear the tank of any hard water deposits. Once complete, close the drain valve and restore power to the water heater. PART 8 – TROUBLESHOOTING The following table details operating issues, possible causes, and service remedies. ISSUE No Hot Water Not enough Hot Water Water too hot or not hot enough Noisy heating element(s) Water leaks POSSIBLE CAUSE 1.
