It is imperative to maintain your gas heating system for winter comfort. Apart from the natural wear and tear, inadequate maintenance or improper usage can lead to issues in your Rinnai heater over time. While some significant problems require professional assistance, cleaning the air filter is easy. Rinnai offers a wide range of efficient and durable gas heaters. A step-by-step guide will show you how to clean your Rinnai gas heater filter.

How Does a Rinnai Gas Heater’s Air Filter Work?

The gas air filter is vital in shielding the blower fan against unwanted elements such as hair, dirt, and harmful particles from entering your heating system. Additionally, it contributes to improving the air quality circulating in your home by purifying it.

When the gas air filter gets blocked, a red flashing light indicates the need for cleaning the heater’s filter to optimise airflow. It is important to note that Rinnai gas heaters do not feature pilot lights.

Easy Steps to Clean & Maintain Your Rinnai Gas Heater Filter:

Proper maintenance of your Rinnai gas heater filter ensures optimal conversion rates. Instead of waiting for flashing light error codes, it is recommended to clean your heater periodically. Please avoid using your Rinnai gas heater when the filter warning is on, as it can lead to overheating. Follow these simple steps to clean the air filters and resolve the filter flashing light issue in your Rinnai heater.

Step #1: Switch Off the Heater

Before cleaning, you must shut down your Rinnai gas heater. Press the power button to shut down the device and unplug it from the outlet.

Step #2: Locate the Filter

You’ll locate the filter cover by removing the back panel from the rear of the gas heater, giving access to the control panel. Using a screwdriver, unscrew the screws and locate the Rinnai gas heater filter around four inches behind the control panel.

Step #3: Remove the Filter

Take caution while performing this step to avoid damaging your Rinnai gas heater. Reach out to the filter, grip it firmly with your hands or an appropriate tool, and gently pull it out.

Step #4: Clean the Filter

The most crucial step is cleaning the filter, and it’s a straightforward process. Turn on a vacuum cleaner and direct the airflow towards the filter blockage. The vacuum will effectively remove all debris from the filter.

Step #5: Reassemble the Parts

After cleaning, you must refit all the parts back to the gas heater. So, put the filter back in its place, screw and secure the control panel. Finally, switch on the device, and you should no longer see a flashing red light on your Rinnai heater.
