I have bought a house with a Rinnai heater which is approx 20years old. In the 5 weeks I have been here it has gone every day first try. Tonight after constant starts it just will not ignite. The spark is there at every push but does not appear to have any gas coming through. No smell of gas at all. Hoping you can help me Lois Le Bas

The obvious question is are you sure you have not run out of gas or has an isolation tap been turned off by mistake. Do you have anything else on gas that is still working ok. Check this one first and I am willing to keep an eye out if you re-post the fault.

How do I turn down thermostat on this water heater?


The temperture of a water heater should be approx 120 degrees. If you use a dishwasher that is the desirable tempurture to kill bacteria.

If your heater has two thermostates then make sure they are set for a 5 degree difference between them

Good Luck,

Marty

Moved into a house with an existing Rinnai system. We have controllers in the kitchen and bathrooms. My understanding was that you can change the temp by hitting the priority button then up or down as long...


You need a product manual for your tankless computer that heats water.
Look on side of unit for label.
Then google that brand and model and add .pdf to search parameter to find possible resources.
Or try Rinnai website for a dose of promotion about how great their product is.
If unit is a few years old (age of unit accessed with serial number), there might be no manuals posted online since manufacturers often drop manuals from website after a few years, assuming most their products no longer function correctly and thus avoid available knowledge for customer to talk specifics... instead telling customer to call service tech who of course does not have manual either because he is a tech and needs one, but got hired last week to his new esteemed position and gets paid by service call not by successful repair except bonuses for recommending replacement unit.

Read the manual. Especially required maintenance, such as deliming yearly and cleaning water filter.
Note resources for maintaining tankless appear on following link except for different brand tankless computer:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime

Also scroll down page to read explanation of high temperature limit for tankless before causing irreversible problem with your computer requiring skilled technician.
Also scroll up on page to read about no error code, since cooler than normal temperatures from tankless computer can be result of common plumbing problems like defective single-handle faucet cartridge. Or power surge, since tankless are not protected from ordinary surge event like power restored after outage.

If your tankless computer is older than 5 years, then assume it will not work better than your 5-year old cell phone or 5-year old laptop, or behave better than 5 year old child. So don't assume you are doing something wrong... just assume it doesn't work despite glossy advertising brochures from tankless manufacturers claiming 20 year lifespan for tankless computers.

Install tank type heater yourself, same day and avoid computer water heaters: Ordinary plumber can fix these units easy.

Smoke fills house when furnace turns on


Assuming not talking soot smoke . new furnaces have a coating on heat exchanger from productions which must be burnt off. Generally the contractor will run unit long enough while on job with customer venting home at same time. should not take to ong to do so if this is what you are experiencing. and dont forget to install a quality carbon monixde detector or 2 as per detectors instructions.

Rinnai heaters


Some products need to cure and release a residual smell which is intensified by any open flame, like a pilot. Normally a petroleum product will do this but Scotchguard could as well. It should fade with time.

My Rinnai dynamo has gone from being 'non smelly' to being quite high in emissions when in use.


Since your heater is a Flue-Less Or Vent-free (as it's called in here in the US), I suspect it needs a thorough interior cleaning. This generally is the cause of "smelly" heater. Keep in mind, flue-less heaters use interior air for combustion. So, whatever is floating in the household air (dust, lint, pet air, etc) eventually gets into the heater and clogs it up, causing incomplete combustion and odors. In addition, fresh paint odors are made worse by the heater. Rug or carpet cleaning products will do the same thing. Even days after they are cleaned. Paint smells may last for a week or more. During these times, the heater should be turned OFF and the house allowed to air out, whenever possible.

All heaters, whether they are flue-less portable heaters like yours or a vented model, should be professionally serviced annually. Usually in the Fall, before firing it up for the Winter.

In case you have misplaced your Owners Manual, I have included a link to it, that you can download and print for future reference.

Turned off heater last night. Tonight turned on and no light, nothing. what's wrong and how do I fix.


Have you checked the outlet plug for power? If there is power at the plug I would look at the fuse on the Main Circuit Board. Have you had any other electrical problems around the house? If you are not up to speed on electricity you should go no further than the fuse. Call a Rinnai service person.

I have a trouble code 11 on my Rinnai model 2532 water heater which indicates no ignition. I checked for gas supply by turning the furnace on which is approx. 1 ft. away, it works. The water heater is...


11 is a ignition failure code. Could be alot of things, I suggest calling a tech who has repaired these before. Pull the front cover off and have a helper turn on a hot water faucet. Look thru the viewing window to see if the unit is firing then going out. If not, clean out the water filter on the inlet side of the plumbing. You will need to turn off the water supply prior to cleaning it. If the unit fires but shuts off seconds after ignition, you may have a dirty or bad sensor. Call a proffessional at this point. Sorry

Heater not heating at the right temperature?


Sir,

Your heater is only a 21K BTU heater. It is not meant to heat a whole house. We don't know how big you house is, however a 21K heater will not heat 4 or 5 rooms. The best you could expect out of a Rinnai 556 would be to heat a couple of rooms that are next to each other. You will never be able to heat rooms in your house that have doors or are down the hall a ways.

Good luck,
