How to adjust the water temperature on your Ace water heater

Read all warnings in your owner's manual and on the water heater before proceeding. The water heater thermostat has been factory set at a setting which approximates 120°F (49°C), to reduce the risk of scald injury. The thermostats are adjustable if a different water temperature is desired.

Turn OFF the electric power to the water heater and then remove the upper and lower access panels. Fold the insulation back to expose the thermostats. Turn the dial clockwise with a screwdriver to increase the temperature setting or counterclockwise to decrease the temperature setting.

Replace the insulation and access panels. Turn ON the power supply.

Replacing the drain valve in your Ace water heater

• Switch the two house circuit breakers dedicated for the water heater to OFF. Wear work gloves to protect your hands.
• Turn off the cold water supply to the water heater. Attach a garden hose to the drain valve located at the bottom of the unit and run the garden hose outside. Open a hot water faucet in the house or flip the relief valve open on the water heater. Open the drain valve and allow the tank to drain until empty.
• Remove the garden hose from the drain valve. Unthread and remove the drain valve from the tank.
• Wrap some thread-sealing tape around the threads of the new drain valve. Install the new drain valve and tighten firmly.
• Turn the cold water supply on to the water heater and allow the tank to fill with water. Once you see water coming out of the hot water faucet, turn the hot water faucet off. Flip the house circuit breakers to the ON position.
