Rinnai model REH-25T-N pilot comes on but will go right back out when you let off button.

Usually happens for two reasons. The thermocouple needs replacing. This is the rod thing that glows red and is the safety for the main gas valve. The cover to the pilot flame has moved or worn away. Often you have to hold the button in for a lot longer than you think. You can also use a gas torch to heat the thermocouple if you can get access to it.

Model rl75. What does code 10 indicate?

A Rinnai fault code 10 is an indication of either an issue with the air intake or a blocked flue. Your first step should always be turning your system on and off to see if the Rinnaifault code 10 has disappeared. If it hasn't, check the vent system for blockages and other issues that could prevent airflow.

Lazer 56

Hi EJAKFbanks,

I believe by your description and my 8 years experience with Toyo Stove repair that you are missing part of the firing sequence. The firing sequence for a Toyo Stove L 56 is to blink on the burner light for 7-9 minutes, then it clicks up to the medium light (amber-yellow color). The medium light blinks and that is when the fuel pump kicks on and starts to pump. If the stove ignites, the medium light will glow for a second and then drop down to the low light (green) The low light will burn for awhile and at this time you will see a blue flame in the newer heat chamber models or a red glow, and perhaps some blue flame in the older heat chamber models, then the stove will kick up to the medium light for a bit, and then to the high light. An EE6 error code will show only when the flame is extinguished after actually taking place and a burn did occur in the chamber on low. An EE6 is usually one of 2 things: 1. There is an inadequate fuel supply for the stove to maintain a low cycle burn, or the medium, or high. Each cycle consumes more fuel than the prior one. Inadequate fuel supply can be due to a restriction in the fuel line such as icing like cholesterol in a persons arteries, or a plugged sump screen, blocked fuel line or filter, too low a quantity of fuel in the tank, or a fuel line that is not all gravity feed, as in, the fuel line runs down, down, and then up a few feet to get to the Toyo. In that case, the fuel has to rely on head pressure to get to the stove. Head pressure is the atmospheric pressure pushing on the fuel in the tank to force it up against the earth's gravity forces. Solution: You can find any restriction in the line, replace the filters, clean the sump screen, put heat on the fuel line to thaw any icing blocks. 2. An EE6 can be caused by a carbon chain developing from the burner ring, flame sensor or chamber wall to any metal part in the burn chamber. A carbon chain essentially "shorts" out the ground for the unit and the Toyo will shut off on EE6. Solutions:You can bang the side of the Toyo (Old frustrated Alaskan solution) which really just jars the carbon chain loose, clean the flame sensor, clean the fuel nozzle with a straight 3 inch wire, and stick a screw driver in the igniter (red wires) hole and rattle it around real good (another old Alaskan trick). Often, those three things will get your stove running again if it is a carbon chain. The problem will likely occur again, but it will buy you some time until you can get a tune-up done. Most likely, you need a tune-up. Question: When was your last tune-up? Toyo's should be tuned up every 2 years. Tthe book says every one year, but in my experience, every two years is the best bang for the customers buck. The three year mark usually begins showing signs of metal fatigue in other parts of the burn chamber/heat exchanger system so the costs rise a little each year, unless you are a lucky Toyo owner and for some odd reason, your stove can go 3 years between cleanings without any ill effect. If you get your stove running, run it hard on High for about 2 hours to clean and burn all the carbon out. Good Luck! toyotech, North Pole, Alaska

Rinnai spectrum 28 can't remove filter

I can't believe no one answered this question properly. When the heater is transported new the fan filter sits below its normal level at the front so it will not slide out. The installer is meant to reposition it when instructing the owner how to operate the heater. you need to loosen the 2 screws holding the bottom panel. Then pull the bottom panel out a bit at the bottom and then lift the front of the filter up into its proper position so it can easily be removed and cleaned. Re tighten the screws in the bottom panel and your done.

Are Kruger tankless water heaters good?

One thing they don't tell you about tankless heaters is that when they turn on, they may cause the lights in the house to flicker. Make sure that you have a good breaker panel (one that is relatively new with plenty of capacity) and run a circuit specifically for the tankless heater.

Rinnai Galaxie 21 Third Burner Button stuck

When turning the 2nd burner on keep the button depressed.

Press the 3rd burner button down untill it stops.

Hold both in that position!

As you slowly release the 2nd burner button, continue pressure on 3rd button while gently wrigling it back and forth/side to side .

As the 2nd burner button is coming up and you fidget the 3rd they will hit a happy medium. This happens around about the middle of slowly releasing burner 2s button.

Dont use excessive force, also if its just been started up you will have to gove the machine 5 mins to warm up before this works.

Can easily upload youtube video if so wish

Runs out of hot water

I wonder if you have this problem below caused by a drop in water pressure from someone flushing a toilet or a washing machine. I would call the company to remedy this issue.

17. What is a cold water sandwich effect? The term “cold water sandwich effect” is a term that is used to describe the introduction of cold water into the hot water supply line during frequent on/off operation of an instantaneous water heater. The cold water sandwich effect, when present, appears as a momentary drop in hot water temperature as it is discharged from a hot water supply outlet (i.e. shower, tub, or faucet). This phenomenon is present in the operation of all instantaneous, tankless style, water heaters, but is minimized with the high tech design of Rinnai water heaters.
The technology built into the Rinnai water heaters is designed to minimize the cold water sandwich effect. Rinnai water heaters are microprocessor controlled and when water flow through them ceases, they remain in a “ready to fire state” for approximately 1 minute. If water flow through a Rinnai water heater begins within the first minute following water flow stoppage, the water heater will fire back up within 1 to 2 seconds. This minimizes the cold water sandwich effect that would otherwise be experienced with a low tech tankless water heater. It should be noted that the cold water sandwich effect cannot be removed completely from tankless style water heaters. The safety standards developed to insure the safe operation of water heaters require a delay in the ignition sequence of all gas water heaters.
While the cold water sandwich effect cannot be completely eliminated from standard plumbing systems, it can be eliminated from plumbing systems that have a supply and return hot water circulating system. Rinnai has developed 2 methods to eliminate the cold water sandwich effect in residential hot water circulating systems.
The first (and preferred) method to remove the cold water sandwich from circulating systems utilizes a small electric tank water heater (powered up) that is used with a dual purpose. The small water heater acts as a mixing tank to eliminate the cold water sandwich effect from the Rinnai water heater and it uses its electric heating element to offset the heat losses from the hot water circulating system.
The second method to remove the cold water sandwich from circulating systems utilizes a small 2 to 6 gallon storage tank installed on the hot water outlet of the Rinnai water heater. This tank acts as a mixing tank to blend the cold water sandwich with hot water and eliminating its effect at fixtures.

My Rinnai 404 gas heater, is 27 yr old and works well. It's on bottled gas. Thinking of upgrading,the new Rinnai has a 6.2kW output. How does this compare to the 404 ? I can't find any specs.

The Rinnai 404 says it has Input: NG, 17 MJ/h, TG 17 MJ/h Propane 17 MJ/h (15 MJ/h (Vic). Let's work with propane at 17 MJ/h. https://www.manual-hub.com/manuals/rinnai-convector-404-01-pdf-manual That's 4.72 kwh according to http://unitconversion.org/unit_converter/energy.html But that's input. I don't know what the efficiency of the unit is, but let's assume 85%. 4.72 * 85%= 4.01 kwh output.
