Question about Heating & Cooling

1 Answer

I have a domestic Rinnai hot water heater, propane. Yesterday I disconnected the gas supply line since I had a new concrete wall being poured and then, once the concrete had been poured, reconnected the line. i have done this several times and the boiler has always started again fine. However, this time i keep getting an error code E02. i tried to reset the boiler several times, it seems like it is starting fine but then reverts back to E02. Any suggestion on how to fix it? Thanks!

SOURCE: Inefficient (big, yellow flame) on wall propane heater, using up propane too fast

A clue to what could be wrong is that you mentioned it took 10 minutes for the pilot to go out. It could be your gas valve. Get a technician in to check your gas pressure both before the gas valve and after. Have them check it as the water heater is running.

Hi Daryl,

It needs a service. The jets carbon up and when they heat up they stop the gas getting through. If you take it to a Gas Shop they will charge you around 90-00 to service it and all they will do is blow it out with compressed air. If you can get hold of an Air Compressor with an Air Blower on the end you can blow it out yourself. Remove the Gas Hose from the back and place the Air Blower into the hole where the gas goes through and hold down the ignitor switch to open up the jets. Give it a good blow out. Once you have done that give the candles a blow as they eget dirty also. You will see a white dust more than likely come out of them. If you want to give it a good clean out remove the cowling and clean (blow out) the inside of the Heater. The cowling from memory has only about 6 or 8 screws holding it on. That should take the top and sides off. I can't remember if you can remove the lower vent on that model - if so it will only be either 2 or 4 screws. Hope this Helps.

Regards
Bryan

SOURCE: comfort glo propane ventless heater won't light

I have several of these heaters in my rent houses and love them. The most problem I have is not being able to ignite the pilot with the user control igniter. Remove the screws that hold the front cover in place along with the front cover. Hold the pilot control down and ignite with a lighter. Keep the pilot engaged until thermocouple is warm enough to keep pilot gas flowing. If it will light this way then you need to blow out the pilot orifice. It seems that every year I have to go in after the summer season when the heater is off and clean the pilot/orifice lines with high pressure air. I believe spiders/bugs/dust block pilot orifice when it is not in use. You can also tell that orifice is blocked when you don't get a good blue pilot flame with pressure behind it allowing the flame to submerse the thermocouple. If the the thermocouple is not getting enought heat it will turn pilot gas off for safety reasons.

Contact Rinna
Some water heaters allows changeover by installing new chipboard or changing dip switches... some do not.
Propane burns much hotter with higher pressure than natural gas

What does it take to convert a Rinnai R75LS water heater from propane to natural gas?


Contact Rinnai.
Gas control valve is different, burner is different, burner and gas valve must match, threads are regular instead of reverse, dip switches probably have to be changed since combustion of NG is not as hot. Maybe different sensors. Pressures are lower with NG.

Hi i have a Rinnia Royale ETR heater and every time i run my gas hot water the heater goes out. It seems as if there is not enough gas to run both at the same time.can you help. thanks Brian


Definitely sounds like there is a gas pressure problem. Are the gas lines feeding both appliances the proper size (at least 1/2" diameter)? Are they natural gas or propane units. If propane, what's the Btu rating of the regulator on the propane tank? If it's to low to handle the two appliance at one time, that could be the problem too.

We have a brand new Rinnai gas heater, Avenger 25. The first two times we operated it, it was fine, but since then a code 13 comes up after 3-4 minutes and the heater turns off. Rinnai said we could...


These are the possible issues with the unit, based on the code list and description

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in the flue outlet.
Ensure gas line, meter, and/or regulator is sized properly.
Ensure gas type and pressure is correct.
Bleed all air from gas lines.
Ensure proper Rinnai venting material was installed.
Ensure condensation collar was installed properly.
Ensure vent length is within limits.
Verify dip switches are set properly.
Ensure appliance is properly grounded.
Disconnect keypad.
Disconnect EZConnect™ or MSA controls to isolate the problem.
Check power supply for loose connections.
Check power supply for proper voltage and voltage drops.
Ensure flame rod wire is connected.
Check flame rod for carbon build-up.
Disconnect and re-connect all wiring harnesses on unit and PC board.
Check for DC shorts at components.
Check gas solenoid valves for open or short circuits.
Remove burner plate and inspect burner surface for condensation or debris.

Clean inlet water supply filter.
On new installations ensure hot and cold water lines are not reversed.
Check for bleed over. Isolate unit from building by turning off hot water line to building.
Isolate the circulating system if present. Open your pressure relief valve; if unit fires, there is bleed over in your plumbing.
Ensure you have at least the minimum flow rate required to fire unit.
Ensure turbine spins freely.
Measure the resistance of the water flow control sensor.
Check for DC shorts at components

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Takes too long for hot water.


You need a recirculating line. You will have to hire a plumber to run a water line from the farthest fixture or to the fixture you are concerned about on the hot side and return it back to the water heater. this will cause hot water to constantly run throught the hot water line (via the recirculating line) and when you want to draw water from the fixture, you will already have hot water right at the line.
I know this works with standard tank water heaters, but it is a lil trickier with rinnai units(but very possible) if your plumber pleads the 5th and tries to sell you another unit call the Rinnai manufacturerand ask them how.

No hot water - Rinnai tankless hot water heater


sounds like the water line is frozen before it gets to heater. You can take a blow dryer and try to thaw the line.You should be able to hook up a hose on the hot side of water heater. turn valve off so it wont flow into house.You can turn on hot water valve on in kitchen but you will have to thaw cold and hot line. Make sure you know where water shut off is to the house just in case a line breaks.

The only way that I have found to work is to place a small electric water heater close to the point of use. Yes this does defeat some of the efficiency of having a tankless water heater but if you figure electric rates are now cheaper than gas rates in some areas, it may save you money.

Another alternative is to put a domestic circulator in-line and recirc the domestic water either all the time or install a timer.

None of these options are "low-buck" options.

15' of 1/2" copper holds less than 1 gallon of water so something is wrong with the heater if it takes 3 gallons to get hot water to the faucet.

Piping of these heaters in tandem is critical. Specified by Rinnai in their design manual, the cold water should be piped to both water heaters with a back-flow presenter installed before the first heater. The hot out piping should be "Tee-d" together and going to your hot water needs.

If piped as per the manual, try turning the water off to only one of the units. Turn on a hot water tap and see if the unit stays on without interruption. Then try the same on the second unit. You may find that one unit has a bad flow control, which is shutting off the flow of water.

You can get more technical help y contacting Rinnai direct at 1-800-621-9419 ext. 207.
