    To troubleshoot why your Rinnai Boiler isn't producing hot water: 1. Ensure the DHW mode is activated by pressing the DHW mode button. 2. Check that there is a water supply to the boiler; wait for the water supply to return or open the water supply valve. 3. If the water pressure is too low (less than 2.3L per minute), DHW mode may not activate; consider installing a pressure device. 4. Ensure the water supply valve is sufficiently open to reach at least 2.3L per minute. 5. The water supply valve for cold water may be too opened.

    If you smell gas, immediately stop the Rinnai Boiler and gas supply. Open all windows and doors to ventilate the area. Do not attempt to light any appliances, as this could cause an explosion. Contact your gas supplier for assistance. Regularly check your gas valve with soap bubbles to ensure there are no gas leaks.

    If you suspect improper water circulation in your Rinnai Boiler, check the water supply and ensure that the CH/DHW pipes are not frozen. If air might not be removed sufficiently, unplug the boiler, plug it back in, and start the test operation.

    To resolve ignition failure in your Rinnai Boiler, first, ensure that the gas shut-off valve is open. Then, turn off the CH mode and turn it on again. If misfire is the cause, check the gas supply pressure by turning on other gas appliances and contact your gas supplier if needed.

    If you smell exhaust gas from your Rinnai Boiler, stop the boiler immediately. Contact Rinnai service for maintenance, as the air inlet/exhaust pipe may not be connected or bent, or the air inlet/exhaust may be blocked.
