![]() If the flame rod or spark electrode has deposits (carbon buildup), use the fine grit paper and cloth to clean or Scotch Brite pad. If the water heater is working properly, the flame should have a clear, blue color with a stable pattern. The flame rod must be in contact with the flame to function correctly. Wires should be without any visible signs of damages or breakage and firmly attached to the rod and electronic board. Some Rinnai water heaters have two and some, one flame rod. The flame rod and the spark electrode (igniter) are firmly attached to the mounting bracket and should not be loose or misplaced. If the ceramic sleeve has cracks or is damaged, replace it. Disconnected or broken flame rodĬheck the status of the flame rod and that it is properly connected. Hire a professional to bleed all the air from the gas pipes. If the gas line has air in it, it needs to be purged. Gas interruptionĪn uninterrupted gas supply is vital for the regular water heater operation. Make sure that your model is using the proper fuel type, per specs. Tankless water heaters can use either natural gas or propane. You must contact a professional technician to fix the problem. Sometimes, due to improper sizing, the gas system is undersized (smaller diameter and insufficient regulator), leading to a higher pressure drop than per specs. Use the specs (found on the label attached to your water heater) to see the proper inlet pressure and check if the unit meets the minimum required. Your gas water heater should get enough amount of gas. If your tankless water heater uses propane, check if there is enough gas in the gas tank (cylinder).

If water is not equipped with the control panel, the same error code appears on the remote controller. You can see diagnostic information on the control panel, where you set the temperature. Here is the list of the main causes of a Rinnai error code 12, also related to "no flame" and flame failure:Īn error code 12 found on the Rinnai tankless water heater means " no flame" or a water heater didn’t recognize a flame in the combustion chamber. It can be found on all models, including V, RU, RL, and RUR series.

The airflow options are standard air or extra air. As a rough guide we suggest:Īlternatively, you can try find the model number of an existing heater and try match it. Generally, 1 kW of heating is needed per square foot of space. Kw/h relates to how much energy is produced per hour. How do heating capacity and airflow options work? If you’re working from home, you can run it in your working space and keep it off in the bedroom until 5pm! *Available on select models.Ħ. For example, on cold nights, you can run the heater in your bedroom and keep it off in living areas. The big answer for that one is zoning*!
