Rinnai model 531 2520FFU 91 N

Hello,
Unit was installed by proffesional less than 30 days ago.
Works great most time.
On occasion unit vibrates badly and very noisy on start up and usually lasts until shut down. May not happen again for week or more.
Vibration actually shakes unit and dishes in cupboard.
Installer has checked and found no problem.
Help!

Have the installer replace the inducer blower assembly. Rinnai will cover the repair and your technician will get paid from Rinnai.

Is there any possibility my Rinnai econoheat850 gas heater can give off carbon monoxide?


Any time there is combustion of any type fuel, from a Rinnai heater to a car engine. There is always a small amount of Carbon Monoxide given off. But, it's usually in small insignificant amounts.

Since your model is a Vent-free or flue-less model, the chances are a little higher. This usually occurs if the heater has not been properly and regularly maintained. Keep in mind, flue-less heaters take in household air for combustion, heat it and send it back out. Whatever is floating in the household air (duct, lint, pet hair, etc) is pulled into the heater. These things can clog the burner(s), the pilot and the Oxygen Depletion Sensor (ODS) and cause incomplete combustion. Which translates into higher than normal Co levels. However, your unit is equipped with an ODS, that will shut the gas off to the heater, if the household oxygen level reaches 25%. Which is not the danger level, which is 19%. Once the Oxygen level returns to 30%, the ODS will release the gas valve and gas will return to the pilot, so that you can relight it.

When properly maintained and operated according to the Owners Manual (see link below) they are totally safe. In the last 20 years, millions of vent-free/flue-less heaters have been sold and operated throughout the world. There has never been a death related to their use.

Certainly, if you or your family think you are experiencing signs of carbon monoxide poisoning, stop using the heater and have a qualified Rinnai technician check and service the heater. If you have other gas appliances in the house, it may be one of them causing the symptoms and not the heater. You may want to have those check and serviced, too.

Have a 1004fa model to heat a room. temp on


You may have a bad circuit board. Depending upon the age of the heater it may still be under warranty. Contact Rinnai (in US) 800-621-9419 with your serial number and installation date. Ask if they can offer a solution. Good Luck!

Rinnai gas heater loud noise on ignition


It may be, Rinnai suggests a maximum length of about 13 equivalent feet of venting including elbows. Add 6 feet for every 90 degree elbow. If the vent is longer than this it is taxing the combustion fan motor and it will start giving you error codes and will not ignite. Remove the trim panel from behind the heater and find the flexable air intake pipe. Temporally remove it from a fitting and test the unit a few times to see if the unit starts quieter. This procedure will be taking room air into the heater for combustion and circumventing the direct vent feature of the heater, not a fix. Have you had the gas pressure tested? It gould be that! You may wish to consider relocating the heater and fire your installation contractor for putting you in this predicament, not Rinnai.

Robert,

If your screen is clean and the circulating fan motor works you will have to remove the front cover. Take the two screws off the bottom and move the front down and off. The top will need to be removed as well. There are two screws in the back. Move the top cover forward and lift it up. You may see the plastic cover that is meant to cover the circuit board is laying down in front of the overheat switch. If so just lay it back over the circuit board.

Keep us posted if this is the case. I have seen two new heaters this way in the last 6 months.

Rinnai R53 Natural Gas Tankless Water Heaters


It sounds like the Rinnai units are working correctly but you've got some plumbing problems.  Any tankless heater has a minimum water flow required to keep the burners going.  If the burners were going with very little water flowing through them to carry the heat away, the heat exchanger could overheat and fail.  The solution is generally to the electronic controls to set the desired temperature and then just use hot water.  Once you start mixing cold water in, you actually reduce the flow of hot water and the burners turn off.  If you are right near the cut off point, the burners will cycle on and off resulting in those very annoying hot-cold-hot-cold showers.  
The fact that you've got those very loud noises indicates some other sort of plumbing problem.  Hooking up two tankless units in series is much more complicated. In heavy draw situations, the second unit is asked to finish heating the water up to temperature when the first unit couldn't quite get it there. Now you're putting hot water into a heater and heating it more.  You have a lot more issues with fluctuating temperatures and pressures within the pipes which could conceivable cause these horrible noises.  Everything's got to be set up right to for things to function properly and it's easy to get something wrong.
From your description, it sounds like a better solution would have been to mount the two heaters in different places. e.g. One in the basement to serve basement and first floor faucets.  The other on the second or third floor to serve those two floors.  Since these units are direct vent (don't use inside air), they can even be mounted in a closed closet as long as the vent can get to the outside.  With this setup you avoid the complexities of a series installation and you also have a much shorter wait time (and therefore less waste) for the fixtures on the upper floors.

Rinnai 1004 - Temp on thermostat reads 10 deg cooler than actual, keeps running


Behind the unit near the floor level, is a yellow wire with a black bulb at the end. This is the actual sensor for returning air. If there is cool air infiltrating the area where it is located, it will keep the unit running until the return air reaches temperature. You could also have a bad sensor but highly unlikely. Make sure there is no air infiltration influencing the sensor. Also, you can unclip the sensor and pull out a few more inches of wire to locate it higher up away from the floor. Tie it up with a wire tie.

Rinnai it testing a remote thermostat but as of yet, there is no plans to offer one.

Error 11 code


If the gas lines are moving or vibrating regularly, especially as they get older there is a possibility of fracture, so I would get them tethered properly. if no obvious vibration or risk of movement then they are probably fine if you are sure there are no leaks other than that i just found this manual earlier on for another user: - hopefully it can answer your questions http://www.rinnai.us/Rinnai.aspx/FileLibrary.aspx/DealerResources.aspx/DocumentsLibrary.aspx/WallFurnacesDirectVentMainHeatSource.aspx/RHFE1004FA.aspx/GeneralInformation.aspx/456RHFE1004FAManual32003.pdf.aspx Hope this helps :)
