Mounting the Tankless Water Heater
Securely mount to wall
One of the first steps in installing a Rheem tankless water heater is securely mounting it to the wall. This ensures stability and safety for the unit. Before beginning, it’s important to choose a suitable location for the water heater.
The mounting surface should be sturdy and able to support the weight of the unit. It’s recommended to consult the manufacturer’s instructions for specific requirements.
To securely mount the tankless water heater, start by marking the desired location on the wall. Use a level to ensure the markings are straight. Next, use appropriate anchors and screws to attach the mounting bracket to the wall.
