Why Disassembling a Rinnai RU 98i May Be Necessary
Disassembling your water heater can become essential for several reasons:

- Replacing worn-out or damaged parts to prolong the heater’s life.
Before you start, it’s vital to understand the process and have the proper tools and safety measures in place.
Preparing to Disassemble Your Rinnai RU 98i
Adequate preparation is key to a successful disassembly. Here’s what you need:
- A set of screwdrivers (Phillips and flathead).
- Adjustable wrench and pliers.
- A bucket or container for draining water.
- Protective gloves and safety glasses.
- The Rinnai RU 98i user manual for reference (if available).
Additionally, ensure the unit is completely powered off and the water supply is shut off. Allow the water heater to cool down for at least an hour before proceeding.
Step-by-Step Process to Disassemble a Rinnai RU 98i Water Heater
Follow these steps carefully to disassemble your Rinnai RU 98i water heater:
1. Power Down and Disconnect
Begin by turning off the unit’s power source. If it’s plugged into an outlet, unplug it. For hardwired installations, switch off the circuit breaker. Then, shut off the gas supply using the main valve and disconnect the gas line carefully.
2. Drain the Water Heater
Locate the drain valve at the bottom of the unit. Attach a hose and direct it to a drain or bucket. Open the valve to let the water flow out completely. Be cautious as residual water may still be hot.
3. Remove the Front Cover
Use a screwdriver to remove the screws holding the front cover in place. Gently lift and set the cover aside to access the internal components. This step exposes the heat exchanger, wiring, and other critical elements.
4. Inspect and Remove Components
Identify the components you need to work on, such as the:
- Heat Exchanger: Detach it carefully to inspect for scaling or debris buildup.
- Filter: Unscrew and clean the filter to ensure proper water flow.
- Wiring Connections: Label and disconnect electrical connections as needed.
Take pictures at each step to ensure accurate reassembly later.
5. Address Specific Repairs or Maintenance
Depending on your purpose, clean, repair, or replace the necessary components. For example:
- Use a descaling solution to clean the heat exchanger.
- Replace faulty valves or damaged gaskets.
- Test electrical connections with a multimeter to ensure they are functioning correctly.
