A reliable heating system is essential to keep your home warm in winter. Installing a gas heater is an excellent option, and Rinnai offers a wide range of efficient and long-lasting models. With regular usage, your Rinnai heater might face issues due to general wear and tear, lack of maintenance and improper use.

While some problems require the services of a professional, you can clean the air filter yourself. Here’s a simple step-by-step guide to help you clean your Rinnai gas heater filter.

How Does a Heater’s Air Filter Work?

Your Rinnai gas air filter safeguards the blower fan from dust, hair, and other particles and improves the air quality in your home by filtering out impurities. However, a red light will flash immediately when the filter gets clogged, indicating it’s time to clean it to maintain proper airflow. Please note that Rinnai gas heaters do not have pilot lights.

Step-by-step Instructions to Clean Your Rinnai Gas Heater Filter

A dirty air filter can significantly reduce your heater’s efficiency. Never wait for the warning light to flash on; clean the filter in advance. When you use the heater with a dirty filter, it will cause overheating. 

Here are the steps to clean the filter and fix the flashing light issue:

Step 1: Switch Off the Heater

Before undertaking the cleaning work, you must turn off your Rinnai gas heater. Press the power button and unplug it from the outlet. 

Step 2: Locate the Filter

Look at the back of the heater, and you’ll see the filter cover. Using a screwdriver, remove the back panel to access the control panel. You’ll locate the filter about four inches behind the control panel.

Step 3: Remove the Filter

Gently and carefully pull out the filter to avoid damaging your heater.

Step 4: Clean the Filter

Use a vacuum cleaner to blow away the debris from the filter.

Step 5: Reassemble the Heater

Place the clean filter back in its position and secure the control panel with screws. Turn the heater back on. The red warning light should no longer be flashing.

Maintenance Tips for Your Rinnai Gas Heater 

Here are the handy tips to keep your gas heater running smoothly:

• Never use solvents to clean any part of the heater.
• Never spray aerosols around the heater.
• Always keep flammable materials away from the heater.
• Avoid placing items on or against the heater.
• Be sure to unplug the heater before you start cleaning it.
• Clean the heater with a soft, damp microfiber cloth.

Rinnai Australia recommends inspecting and maintaining your heater every two years. If you face issues like a damaged power cord, you should have your Rinnai gas heater repaired and serviced by Rinnai or a Rinnai-approved licensed technician.
