Removing the Old Water Heater

Proper removal of the old water heater is essential to prevent damage and prepare for the new unit. Follow these steps carefully:

1. Drain the Old Water Heater: Attach a garden hose to the drain valve at the bottom of the unit. Place the other end into a drain or outside. Open the drain valve and allow the tank to empty completely.
2. Disconnect Plumbing Connections: Turn off the water supply and disconnect the hot and cold water lines using an adjustable wrench. Be prepared for residual water to spill.
3. Disconnect Electrical Connections: Turn off the power supply at the breaker. Carefully remove the electrical wiring from the water heater, noting wire connections for reinstallation.
4. Remove the Old Unit: Once disconnected, carefully lift and remove the old water heater. Use proper lifting techniques or assistance if the unit is heavy.

Preparing the Installation Site

Preparing the space ensures your new Ao Smith water heater fits properly and operates efficiently. Consider the following:

• Check the Space: Confirm the location has enough clearance as specified in the manufacturer's guidelines.
• Install a Drain Pan: Place a drain pan underneath the new water heater if required by local codes or for added safety.
• Inspect the Flue and Venting System: Ensure venting systems are clean and compatible with the new unit.
• Verify Power and Water Connections: Make sure the electrical outlet and water lines are accessible and in good condition.

Installing the New Ao Smith Water Heater

Follow these detailed steps to install your new Ao Smith water heater properly:

Positioning the Unit

Place the new water heater in the prepared location, ensuring it is level and stable. If necessary, use shims or a level to achieve proper positioning.

Connecting Water Lines

• Attach Cold Water Supply: Connect the cold water inlet pipe to the water heater’s inlet port using plumber’s tape on threaded connections to prevent leaks.
• Attach Hot Water Outlet: Connect the hot water outlet pipe to the outlet port, also using Teflon tape for a secure seal.
• Use Flexible Connectors: If your water lines require flexible connectors, attach them securely to avoid stress on the fittings.

Securing the Electrical Connections

• Turn Off Power: Confirm power is off before connecting electrical wiring.
• Connect Wires: Connect the electrical wires from your home to the water heater’s terminal block. Typically, this involves matching color-coded wires (black or red for hot, white for neutral, and green or bare copper for ground).
• Secure Connections: Use wire connectors and tighten all connections securely.
• Restore Power and Test: Turn the power back on and verify that the water heater powers up correctly.

Final Checks and Testing

Before finishing, perform a thorough inspection:

• Check for Leaks: Turn on the water supply gradually and inspect all fittings and connections for leaks.
• Flush the Tank: Some models require flushing to remove debris. Follow manufacturer instructions.
• Set the Temperature: Adjust the thermostat to the recommended setting, typically around 120°F (49°C).
• Test the Unit: Turn on hot water faucets in your home to ensure hot water flows properly and the unit operates without issues.

Maintenance and Troubleshooting

Proper maintenance prolongs the lifespan of your Ao Smith water heater and ensures optimal performance. Regularly check the anode rod, flush the tank annually, and inspect for leaks or corrosion. In case of issues like no hot water, insufficient heating, or leaks, consult the user manual or contact a professional plumber for assistance.
