Repair and operation of Rinnai boilers

Installed a wall-mounted gas boiler Rinnai 207 RMF. Switched to propane/butane, inlet pressure 334 mm of water column, DHW pressure 2 - 3.5 kgf/cm2, pressure in the heating circuit 1 kgf/cm2. I switched sw1 to the operating position from propane-butane (dips No. 1,2,4,5 on), powered through the stabilizer. Whenever you try to turn on the unit (no matter heating or hot water), after about 30 seconds error 43 32 lights up and a sound signal sounds. When you turn it off and on again, the error disappears, but I turn on the hot water supply on the remote control, open the water, and it appears. The same without turning on the DHW, but only for heating (the blowing turns on, works, and an error occurs). Where to see? There are two errors in the instructions 43 and 32 - here all the parameters are normal.

There should only be one error light. The second number is not an error. The error on your model is the first number. Raise the pressure to 1.3-1.5.

The Rinnai RB-367 gas boiler does not start in DHW mode and only works for 3-4 minutes when the heating is turned on. The batteries do not have time to heat up. How much will such repairs cost?

It seems that the flow sensor is not working or there is not enough water pressure to open it. You need to check if the heat exchanger is clogged and see how the 3-way valve works. The reason may also be a board failure.

Wall-mounted boiler RB-107 emf 12 kW. When starting up, error 99 appears every other time. How much does maintenance cost, and is repair included in this amount?

Annual service maintenance implies complete cleaning, adjustment and diagnostics of it technical condition. Detected faults are removed if this does not require spare parts or labor-intensive repairs. Error 99 means the exhaust is closed and requires checking the chimney and fan, and the permeability of the heat exchanger.

Boiler RB 207 RMF. Tell me what pressure should be in expansion tank, and which one is in the additional one? Now in additional tank 1.3 in a system 1.5, three floors are heated, the pressure does not drop, but it gets airy on the top floor, no leaks were found, it’s dry everywhere, I don’t understand the reason.

The pressure should be the same everywhere; if the 3rd floor becomes airy, it means there is an air leak somewhere, or there is air in the coolant. Make sure that the system pressure is 1.8 bar, and then check.

Boiler from the rb 107-167 emf series. Lately there has been a problem with the temperature of the hot water supply, often the maximum is 38 degrees, or even less, sometimes 42. I noticed that the temperature drops when the pressure is stronger, but it is constantly walking. You have to reduce the pressure, and then it becomes 45, if you increase it a little, then 34-36 degrees. But this had never happened before, although the pressure was also not stable. It feels like the aggregate has stopped coping with the pressure. Is this a heat exchanger?

Check (clean) the burner. You may need to rinse it. And in general, on low-power models this problem often occurs in the spring. They are weak.

The Rinnai gas double-circuit boiler did not work all summer, now we tried to start it, but it only gives error 14. Please advise what we can do without calling a technician?

The error code indicates a lack of coolant circulation in the heating system. First of all, make sure that gas is supplied, the pressure is normal, and the coolant is filled in full. Check that all radiator valves are open. If all this is in order, then most likely the circulation pump jammed during the downtime. Unscrew the rear pump plug and turn the armature using a screwdriver. Often this is enough to start the unit.

The boiler does not turn on the heating system: soon after starting it goes out and shows errors 12 and 15 alternately. I have already washed all the batteries, but it did not help. How can I act independently?

Error codes indicate system malfunctions in the operation of the device, and it is difficult for an untrained person to find the cause of the malfunction. The first thing you need to do is check the integrity and cleanliness of the heat exchanger. It is necessary to measure the gas pressure at the inlet and inspect the chimney for correct design, check the operation of the fan.

The Rinnai gas wall-mounted boiler recently made a loud noise when turning on the hot water, but now it won’t start at all - there is no heating or water heating. How can I fix this on my own?

If the heat exchanger is clogged, you can wash it yourself using a strong solution citric acid. It is necessary to keep the poured solution for a long time so that all mineral deposits on the walls dissolve. There is also an option for the cause of the problem - the flow sensor is clogged. It is necessary to check the condition of the sensor and replace it if necessary.

I have a Rinnai 107 boiler. In terms of heating for my area, it is quite sufficient, but in terms of DHW performance it is very sad. Is it possible to improve it by installing a heat exchanger and/or burner from older models?

Boiler indirect heating put it. Or change the unit to a more powerful one.

18 kW model, RB 166 GMF. The problem is this: 1. The heating, if it turns on at low degrees (40 C), then after working for a minute, it turns off. I turn it off and on again using the remote control - same story. I turn it on again and slowly increase the temperature, it starts up at 60-70 degrees, but it starts to work unevenly, i.e. the fan is catching up, the burner is fully operational, then the burner fails and the burner is at half heat, and so on in a circle, then it goes out, then will go out. It's the same with hot water supply. And if you turn on the hot water supply while the heating is running, it displays error 16. House in a rural area 56 sq.m. The technician came, washed it, it seemed to work, but after a short time, when I started using the hot water supply, it went into error 16. It turns out that heating and hot water work separately, but together they go into error. The technician says it's a temperature sensor or a three-way valve.

It looks like there is no coolant flow, the boiler is overheating. Look at the mud man. But where there is no flow, we need to figure it out, I would start with the secondary DHW heat exchanger. Rinse the unit thoroughly so that the pipes in it shine.

Nowhere can I find a clear explanation of the logic of the so-called “absence mode”. Model EMF107. I would like to understand what is happening in this mode. Maybe it was just made to provide +5. Monitoring the air temperature in the room is good, of course, but apparently the logic of the work is such that if the temperature drops even one degree from the set one, the unit begins to work at its full maximum, the meter goes off scale, and the radiators literally become red hot. I heard about the absence mode, which supposedly maintains the temperature of the coolant at 20 degrees. I also read that if you read the instructions, it says that in this mode it works for 10 minutes and rests for 4 hours. I re-read the entire instructions - there are no such words there. But even if this is so, the question remains - in what mode does the device operate? Does it fry for 10 minutes at its full maximum or is it somehow guided by the user settings of the remote control?

I wouldn't experiment with this mode. Especially when it’s -15 or even less outside. It is better to make sure that in any room of the house there is at least +5 so that the radiators do not freeze.

Error 16. Overheating of water when open tap for hot. What to do? Rinse?

Flush the heating circuit so that the DHW heat exchanger is flushed. This is the reason.

Error codes for Rinnai gas boilers

Error 11- It shows no flame due to a malfunction of the ignition system. The flame is not recognized, it may light up and go out immediately. It is necessary to check the presence of gas in the gas pipeline, the serviceability of the connection and the location of the ionization sensor. Turn off and then turn on the device again. A possible cause is contamination of the main heat exchanger plates.

Error 12- This fault indicates that the unit goes out more than 20 times after ignition. It is necessary to check the cleanliness of the radiator fins, the functionality of the fan and the proportional control valve.

Error 14- There is overheating or a malfunction of the temperature sensor. The sensor terminal may have broken or there may be a problem with the electrical circuit security. The control unit should be replaced or the wire connection in the terminal should be checked.

Error 15- Malfunctions in water circulation. To solve this problem, check for normal water flow, damage to the pipelines, or recharge the unit. If the issue is not resolved, reboot it.

Error 16- It appears when the coolant overheats and boils. Occurs if the heating thermistor records a temperature above 95 degrees for more than three seconds. Troubleshooting involves removing air from the pipeline and cleaning the heating filter. It is also worth checking the operation of the three-way valve, to find out if there is a breakdown in the heating thermistor, for which measure the resistance of both terminals.

Error 20- This problem occurs when incorrect installation DIP switch. It is necessary to check the correctness of the DIP switch parameters.

Error 34- Indicates a problem with the thermistor at the DHW output. To understand how to fix this failure, check that the thermistor resistance matches the diagnostic table. If not correct, replace the thermistor.

Error 43- This fault indicates a low coolant level. Lights up when recognized by sensors low level water for 43 seconds. You should check for a short circuit in the water level sensor and for damage to the make-up valve. Then feed the unit with coolant, turn the device off and on.

Error 61- Indicates that the fan motor is faulty. Namely, it is impossible to regulate the speed of rotation or it does not work at all. It is necessary to check the voltage and resistance of the fan windings and, if necessary, replace it with a new one.

Error 62- It appears when the temperature fuse has blown. It is also possible that the combustion chamber is clogged.

Error 89- Occurs when completely frozen. Check that the ceramic heater and thermistor are operating correctly. After thawing, it is important to inspect all components of the device and replace if damaged.

Error 90- Indicates problems with the fan automation. It is necessary to inspect the correct installation of the chimney and air supply pipe. Also inspect whether the heat exchanger plates are clogged.

Error 99- Lights up when a fault occurs with the release of combustion products. We check the cleanliness and tightness of the chimney and air supply pipe.

The cap on the air vent of the Rinnai 307 wall-mounted boiler pump has burst. Can it be replaced separately?

The main thing is to know that only the spool cap is damaged, and the diverter mechanism itself is working and can hold pressure. You should also understand whether the heat exchanger needs cleaning. If circulation pump OK, change the cap.

We installed and connected the Rinnai 207 RMF boiler. I found connector CN16 on the board, but there is a similar connector CN20. Isn't it him? I found the service manual on GMF. There really is a CN16 connector. But the RMF board has a different arrangement of connectors and components. I tried to turn on the unit by closing pins 1 and 4 on connector 20, but there was no effect. I need to force it to turn on using an external thermostat, regardless of the settings of the native remote control. Can anyone tell me what is wrong and what needs to be done for this?

Factory settings - when open, 1-4 works, when closed, turns off. Switch 5 DIP to SW2 and on the native remote control set the temperature to more than the additional one. thermostat, or turn on the heating system temperature.

The RB 307 RMF boiler does not work due to errors 43 and 52. What is the problem?

These errors mean serious disruptions in the functioning of the unit: a drop in coolant level below the permissible level and problems with modulating gas valve. You will need to disassemble and clean the gas valve, filter, and check the sensors.

On the Rinnai 207 double-circuit boiler, when the coolant pressure decreases, two errors appear simultaneously: 32 and 43. If the 43rd one is clear. Why does the 32nd error appear - a problem with the freezing thermistor? When the pressure in the heating system is normal, the 32nd error has never appeared separately. The device is new. Just launched.

The error on the display is only the first number.

The Rinnai boiler goes out immediately after starting due to error 11 - supposedly no gas is supplied. But in fact it arrives: the pressure on the gas tank is always 3.5. What's happening?

This could be a failure of the flame control sensor, the solenoid valve that controls the gas valve, or board combustion.
Perhaps the pressure reducer is stuck and does not provide enough gas to start.

The boiler recently began to hiss, but now it has stopped and given error 15 - something with the modulation valve. What can be done?

The gas valve needs to be replaced.

Malfunction of the Rinnai RB 307 RMF boiler - after washing the heat exchanger, it worked for half a day and stopped with error 14. What can be done?

The error indicates a malfunction of the temperature fuse. First you need to make sure that there is no short circuit there or that there are no breaks in the circuit. Find out if there is potential between zero and ground: this also causes malfunctions in the operation of sensors and automation. The STB button could have been triggered by a signal from the sensor. It is necessary to check all sensors according to the service instructions to ensure that the sensor resistance corresponds to the temperature parameters. If there is a discrepancy in the values, the faulty sensor should be replaced.

There is a malfunction in the operation of the RB-207 RMF boiler, it gives error 14, problems with circulation. You turn it on, the pump starts, then the turbine, the burner does not ignite. Immediately it shows error 14, the same thing for hot water supply.

Check the overheating fuse on the combustion chamber (two black wires).

Gas wall-mounted boiler RB-107 EMF in operation since November 2014. On the remote control last days Errors appear after using DHW: 11 - No flame and 15 - Problem with water circulation. You can start it after the indicated errors appear only by disconnecting it from the network for a few minutes. I checked the possible causes, which are indicated in the instructions, everything is normal and the presence of gas and pressure in the system (1 on the pressure gauge) and there are no damages or leaks. As a result, I was forced to turn off the hot water supply using the remote control. Please tell me what to do, what spare parts to buy?

The burner needs to be cleaned. It is dirty and does not allow it to enter the combustion chamber. required amount air for combustion. Because of this, after ignition there is little heat, and if after 5 seconds. The heating sensor did not detect an increase in temperature. The device understands that there is no circulation. And it gives error 15. Error 11 for the same reason. When igniting, due to lack of air, the flame height is low and the combustion sensor does not have time to heat up. Remove the cover and everything will work.

Rinnai 367 began to give hot water intermittently - hot for 2 minutes, then cold and hot again. What is the reason for this failure?

First of all, you should check the serviceability of the flow sensor - see if it is a stepper or an impeller, provoke it to work. Then make sure that the primary is not clogged and secondary heat exchanger.

The boiler began to leak slightly. We opened the front cover, and there was corrosion everywhere. What can be done?

If it comes to the corrosion of the lid, then the leak has existed for a long time. It is necessary to replace gaskets or clean contacts and components.

When turning on the hot water, the unit often began to display error 16, although this does not happen when only the heating circuit is operating. What could this mean?

This error means the heat exchanger is overheating. It is necessary to periodically carry out maintenance of the unit, which includes cleaning the heat exchanger, checking the operation of the pump and 3-way valve, cleaning contacts and checking sensors, adjusting electronics, tightening connections.

The Rinnai double-circuit boiler does not work in mode hot water supply, and the heating system is already turned off. Shows error 16. What can I do?

In this case, the error means overheating. It seems that the 3-way changeover valve is faulty, since the automation does not recognize that the heating circuit is no longer active.

The Rinnai 307 unit stopped with error 14 displayed. Why did this happen, and how can I fix it myself?

The error indicates circulation safety problems. Most likely, the dirt filter is clogged or the pump is jammed. This happens when the unit has not been started for a long time. More possible reason- malfunction of temperature sensors.

The boiler unit stopped with error 14 displayed. What to do in this case?

The error code indicates that the automation has blown the fuse for the coolant, that is, overheating has occurred. The fuse can be returned to its place independently using the button under the cover on the outside of the case. The procedure is described in the operating instructions.

The Rinnai boiler stopped with error code 16. What does this mean and how can I fix it?

The error indicates overheating (boiling) of the coolant. First of all, you need to check whether all heating distribution valves are open and whether the pipeline is clogged or whether there is air in the pipes. It may be a pump or a clogged filter, or the three-way valve may also be faulty. The boiling sensor may have failed.

The Renai gas boiler stopped with error code 99. Allegedly problems with draft. But the chimney is clean. What could it be?

The error code indicates a dirty chimney. But if you claim that the chimney is free, then the reason is a clogged heat exchanger. The presence of potential between 0 and ground can also interfere - it “deceives” the sensor, and it gives an error signal. The sensor itself very rarely fails.

At the dacha, the Rinnai 167 boiler stopped. It gives error 14. What can you advise?

Error 14 means problems with the safety of fluid circulation, that is, either the dirt filter is clogged or the coolant temperature sensor is faulty.

My Rinnai rb 367 rmf boiler is in its second year of operation, but before that it was sitting for a long time. After setting the pressure to 1.5 atm in 3 places, the gaskets immediately leaked. I had to turn it off. Why didn't the valve work?

Since the valve did not work, it means that there was no critical pressure for this. But rubber gaskets have their own service life, apparently they need to be changed.

The Rinai 40 kW gas boiler operates for no more than 15 minutes and turns off. It gives error code 99. How to fix this?

Judging by the error code, the tightness of the exhaust system is broken. There may be several reasons: problems with the chimney, the heat exchanger is clogged, the fan does not work, the traction relay has failed.

A Rinnai rb 367 emf boiler was installed in the heating system. Operation since 2009 In the summer, I carried out a full maintenance, replaced the three-way valve, dispenser, emergency release valve, mud filter, circulation pump, and washed the hot water heat exchanger. Now a problem has arisen: when you turn on the hot water, the pressure in the heating system drops to 0 after a couple of seconds. You have to turn off the boiler every time to use hot water, then turn on the make-up and turn on the boiler. Accordingly, cut off the hot water supply. Tell me what's wrong? I suspect a three way valve?

The valve has nothing to do with it. The DHW heat exchanger is poisoning. The DHW and CO circuits are mixed, so when turned on DHW mode the pressure in the heating circuit drops. In short, the DHW heat exchanger needs to be replaced.

Malfunction of the RB-367 RMF boiler. Error 18 appears when you turn on the DHW, but it may not always work for several days, then it appears, turn it off, wait further, everything works again. I noticed that if it is turned off for about half an hour, the error appears faster than if it is turned off, say, all night. And yet, the error appears only at the moment of switching on; if the gas lights up, everything works fine.

Error 18 is a ground fault detection. In case of a certain voltage offset (more than 5 V) in the electronic module line - Check the voltage between the third pin CN3 of the electronic module and the ground line. Check the cable coverage (especially the control panel cable).

The following malfunction of the Rinnai 207 boiler occurred - strong pressure drops in the heating system during intermittent operation, i.e. when a break (30 minutes) the pressure drops to 0.5, during start-up and heating the pressure reaches 1.5. This is fine? I didn't notice such a difference before. In operation for 5 years.

You need to check the pressure in the expansion tank.

Please tell me about the settings of the 207 rmf boiler. What water pressure should be supplied to it? The instructions say about pressure reducer, but there is not a word about the pressure itself. Question for users: There are absence functions and a programmable heating function. Do you use them and under what circumstances? permanent residence. What is the difference between setting the heating mode, which is controlled from the remote control? It seems to me that it is more economical to simply support constant temperature than to reheat the room.

The remote control has 2 modes - coolant temperature control and room temperature control. Which mode to use is up to you. Many users have the room temperature control mode set, they do not approach the boiler and the house is comfortable.

Domestic consumers mainly associate Rinnai with the production of high-quality and functional air conditioners, but it produces not only this climate control equipment. Relatively recently, heating equipment manufactured by a Japanese concern appeared in the Russian Federation.

Judging by consumer reviews and operating experience, Japanese Rinnai gas boilers, like all other brand products, are distinguished by reliability, functionality, thoughtful design and control system.

Construction of Rinnai heating boilers

The main philosophy of the Rinnai company is the following:

All these three points are reflected in the company’s line of heating equipment. The following modifications are presented:

• Rinnai RMF series - the modification includes equipment with the ability to connect to the system " smart House" The main difference model range is the active gas saving mode. When the DHW is turned on, the burner can operate in three modes, providing the necessary heating.
  Additionally, a high-speed heating unit is provided, which allows you to get hot water immediately after opening the tap. Another innovation that Rinnai RMF mounted double-circuit gas heating boilers have is that the heating of the coolant is controlled by two microprocessors at once, correcting each other’s operation. It is possible to set a daily operating mode gas equipment, taking into account the characteristics and preferences of the consumer.
  Room thermostats connected to the control unit help further reduce gas consumption for heating.
• Rinnai EMF - economical gas consumption is achieved through proportional flame control, with the aim of low nitrogen oxide emissions, which makes it possible to prevent heat loss. Traditionally, the ability to maintain the temperature of warm water is used. The 3-way valve ensures stable heating, regardless of the number of users and pressure.
  The individual wall-mounted double-circuit gas boiler Rinnai EMF has the provided function of simultaneous connection of both the main and additional heating systems (warm floors).
• Double-circuit gas condensing mounted heating boilers Rinnai CMF equipped with an advanced control system for automatic regulation the volume of the flame and heating the water to a certain temperature. The control unit helps to select the optimal boiler operating mode for the next 24 hours to avoid excessive fuel consumption.
  Household condensate wall-mounted double-circuit gas heating boilers Rinnai, CMF series, remove combustion products through coaxial chimney, which speeds up the installation process and makes it possible to install stations in multi-storey buildings.

All models of Rinnai boilers are energy-dependent and stop working when there is a power outage. Microprocessors used in automation are sensitive to voltage drops in the network. For stable operation you will need to install the source uninterruptible power supply, generator or battery.

Installation and connection of the Rinnai boiler

Installation and connection of a finished heating system to a Rinnai boiler requires certain qualifications. Consumer reviews show that the main problems and difficulties that arise during operation largely depend on errors made during installation.

The manufacturer indicates the connection procedure and the basic requirements for installation:

Increased consumption of liquefied gas often occurs due to incorrect settings. To check compliance with the operating conditions and ask the necessary questions, you can use the QR code and use it to mobile device go to the official website of the manufacturer.

Operation of Rinnai boilers

For a private house or apartment, Rinnai boilers are an almost ideal option. Almost all settings are performed automatically. The control unit has a display that displays all operating indicators: pressure in the expansion tank, heating temperature, system volume, operating mode, etc.

When the gas pressure is low, a warning is also sent to the monitor, and the station is automatically switched to economy mode.

Remote control of the boiler can be carried out using a remote controller installed in one of the rooms or a remote control. Several room temperature sensors can be connected to the controller.

The gas valve may need to be adjusted periodically. This will allow you to set the minimum consumption of bottled or main gas.

After operational failures due to a power outage, all settings remain in the processor memory and are installed automatically.

Choosing a wall-mounted gas boiler Rinnai

Almost all modifications of boilers have the same technical characteristics and performance. The difference mainly lies in the degree of automation of the equipment operation control process, as well as the presence of systems that ensure environmentally friendly and economical gas combustion.

All models have a secondary heat exchanger, which ensures rapid heating of water, but in the RMF series, the consumer receives hot water instantly.

Rinnai boilers are reliable and easy to use. Good decision for those who primarily value comfort and unlimited financial resources.

Japanese heating devices Rinnai has long received high marks from consumers around the world due to its efficiency, which is achieved by introducing original technical solutions. These heating units differ markedly from analogues in their increased efficiency and minimal emissions of harmful substances in environment.

Peculiarities

Rinnai is one of the most famous Japanese equipment manufacturing corporations high level By affordable prices. It appeared back in 1920. In the process of producing their products, the concern’s specialists use the most interesting original ideas and Newest technologies, which allows you to create the most productive and economical devices for heating systems.

Characteristic features of devices from the famous Japanese brand:

• heat exchangers are made of high-quality copper;
• high environmental parameters;
• the ability to control the unit remotely from a mobile phone;
• convenient control panels;
• compact dimensions;
• efficient operation even at reduced gas pressure levels;
• regulation of the fuel combustion process;
• increased efficiency;
• Quiet operation and no vibration.

It should be noted that the price of gas units from Rinnai will be affordable to any average person, which distinguishes these devices from analogues produced by other well-known companies.

Any product from the Rinnai brand will stand out for its excellent functionality, 100% reliability, and simplified operation. If a sudden power failure occurs or the fuel pressure level drops, the device’s sensor will immediately receive a warning about this, and the device will automatically switch to economy mode to avoid subsequent problems. Products from Rinnai can easily operate on any type of gas - it doesn’t matter whether it is natural or liquefied. Heat will be generated by burning gas through burners that have a special technical design, their operation will produce a small amount of nitrogen oxide.

At the same time, consumers should know that despite the fact that Japanese units have the most outstanding characteristics, their design and operation are quite simple. The body of the product is made of durable steel, which is coated with a special powder paint. The main elements of the devices are protected from various impacts by foam filling. All popular models of the manufacturer have an automatic flame adjustment system.

All processes occurring in the device are under control electronic sensors. You will never see soot in these devices due to the fact that the fuel in them will burn without residue. The new ventilation type burner will regulate itself required proportions air and gas, which will significantly increase the efficiency of a particular device even at a low level of fuel pressure.

Types and series

Today, the manufacturer offers consumers a choice of 4 series of devices under the abbreviations “RMF” and “EMF”, “GMF” and “SMF”. Each of these series is intended for use in strictly defined conditions.

Products of the “RMF” series will be able to heat a space with an area of ​​180 to 420 m2.

Their main characteristic features include:

• possibility to program the launch desired temperature for heating the home 7 days in advance;
• just before starting work, the coolant present in the product will be preheated, which, in turn, will accelerate the rate of warming up the room;
• Availability remote control device.

The “RMF” series comes complete with one of 2 types (Standard option and DeLuxe option) of control panels. Using a standard remote control, you can program the operation of the unit for 12 hours in advance, which is extremely convenient. Using the DeLuxe option, it will be possible to store as many as 5 modes in the remote control’s memory (calculating operation 24 hours in advance).

Rinnai also produces a very specific series of “EMF” units with two circuits. All of them are suitable for heating spaces ranging in size from 110 to 410 m2, which will allow them to be used to heat fairly large and even multi-story buildings. This series of devices is complemented by a special type of burner, which can be used to minimize emissions of toxic components during fuel combustion in the system. In addition, Rinnai EMF is completely safe for daily use. They have built-in automatic fuel and electricity shut-off systems. There is also a device that stabilizes the voltage.

GMF devices are equipped with the most interesting performance characteristics. They can warm large areas– from 100 to 400 m2, which is quite suitable for private houses.

"GMF" series has such characteristic features, How:

• protection against freezing (this is why even due to a sufficiently low temperature the boiler will not be damaged and will continue to operate);
• electric spark ignition system;
• self-diagnosis - with its help, the user can independently quickly find a breakdown and easily eliminate its cause;
• Certain models are equipped with a circulation pump.

Boilers are installed where the coolant pressure level is not very significant. For this reason, they are most often purchased for use in rural areas and in holiday villages. It should be noted that it is quite easy to repair all models of the manufacturer if necessary. Spare parts for the product “Rinnai RB-GMF” and similar ones are easily found in specialized stores, and the consumer himself can fix a boiler breakdown without contacting specialists.

The main advantage of this series is environmental friendliness due to the minimal release of toxic waste into the atmosphere. The automation unit here has 3 levels; flame regulation and the heating level of the coolant can be determined depending on seasonality and climatic conditions. Diagnostics of all possible errors is displayed on the screen in text and (or) in the form of a digital code. Correcting the fan operation will protect against a lack of oxygen for purging. The power of this type of unit will be 12-42 kW. The most popular models from this series are RB-166, as well as 206 and 256, 306 and 366.

The SMF series has many interesting features. The most important of them can be considered the ability to easily switch from natural gas to liquefied fuel, just by replacing the nozzles in the device. The amount of CO2 produced during fuel combustion is no more than 5.72%. Units of this series are produced for heating spaces from 100 m2. Thanks to automatic regulation, the products will operate even at low fuel pressure levels.

The series boilers have 2 heat exchangers, one of them is copper, the other is steel and is quite efficient, it guarantees heating of the coolant up to 14 liters per minute. In the combustion chamber, the fuel and air mixture is adjusted, which is proportional to the volume of fuel used. This can be achieved thanks to a turbocharged burner. The functionality of the products will not depend on the climate. The emission of harmful substances is minimal, so you will not see any soot or traces of scale.

Using innovation in the production of its units, the Rinnai concern also produces and sells condensing products. Units of this series have increased environmental safety indicators in terms of the amount of carbon monoxide released into the environment. This is one of the features of fuel supply to the burner. The fuel and oxygen are homogeneously mixed, then they go together to the burner. Carbon monoxide will necessarily pass through special holes located in the heat exchanger, so in this case carbon monoxide will also give off its heat to the system.

Most popular models

RB-167EMF

The convection device has a power of approximately 18.6 kW. It is compact in parameters and includes a fuel combustion chamber in its structure closed type. Using a special burner, the liquid in the coolant warms up to 85 degrees, and in the hot water circuit - up to 60 degrees. The performance of the 2nd circuit is up to 10-12 liters per minute. You can easily connect a “warm floor” system to the product. In addition to the device, there is a room thermostat.

Positive aspects of using the product:

• the combustion system will extend the service life and reduce the number of harmful emissions;
• Regulation of the circuit according to the air temperature parameters in the room;
• increased efficiency – 93-94%;
• excellent operation even with significant fluctuations in the level of fuel pressure in the main networks;
• a circulation pump, an 8-liter tank, and a dirt filter are provided

Rinnai RB-327CMF

This unit is also a condensing unit. Its main advantage can be called high efficiency. Thermal power The device reaches 35.5 kW, the largest heating area is 372 m2. The product is located in a strictly designed case, on which you will not find a control panel - all controls will be located on the thermostat. You can also connect external control modules that operate via a GSM channel to control work from a distance.

RB-167RMF

The original unit is complemented by a control unit with a color screen. The device has a circuit with closed camera combustion of fuel, which takes oxygen both from outside and from the room.

Characteristics of this model:

• remote control using a mobile phone;
• DHW temperature control program;
• weather-compensating automatic system;
• the ability to regulate the heating circuit according to temperature in all rooms.
• self-diagnosis;
• connecting a voice controlled thermostat.

Rinnai engineers have added a combustion system to the boiler, which is characterized by 100% fuel combustion with a significant reduction in the amount of toxic substances emitted into the atmosphere. The first heat exchanger is made of copper, the second is made of steel. On board the unit there is the necessary piping for operating the system - from the tank to the safety system.

User manual

For own home or ordinary apartment Rinnai products can be considered simply an ideal option, which is why domestic consumers are increasingly choosing them. Almost all settings are made in auto mode. The control unit has a screen on which you can find all the necessary indicators: pressure level in the tank, heating temperature, operating mode of a particular device.

When the fuel pressure level is reduced, a special signal also appears on the display, and the unit automatically switches to economy mode.

The product can be controlled remotely using a portable controller, which is usually installed in any room of the home, or is controlled using a remote control. A number of sensors that measure room temperature are connected to the controller.

From time to time it may be necessary to adjust the gas valve. This will help reduce the consumption of gas in cylinders or main fuel.

After operational failures due to a power outage, all settings are saved in the processor memory, and are automatically restored after troubleshooting.

Repair

Intelligent control of Japanese boilers allows you to display information about operational failures or product malfunctions on the display in the form of a specific code.

The Rinnai boiler may go out immediately after starting operation due to errors "11"- this is a signal from the product that fuel is not flowing into the system. The sensor that controls the flame level may have failed and is not working. solenoid valve, on which the performance of the gas valve depends, or the board simply burned out. This can also include sticking of the pressure level reducer and lack of fuel level required to start the system.

Code "12" appears on the display when the flame dies out more than 15-20 times. This happens due to low fuel pressure in the system or due to the presence of debris on the burner itself.

Code "14" indicates that there are certain breakdowns in the boiler operation control electrical network that can be resolved independently.

Code "15" indicates that the circulation of the coolant has been disrupted. The circulation pump of the product is in a single copy. If in hot water supply or heating mode this pump does not drive water through the heat exchanger, then this will happen main reason failure. It is necessary to slightly open the plug of the pump itself and see whether the rotor is working or not. To adjust it, you can gently push it with a screwdriver so that it starts to move. You can also clean the fluid filter.

Error "18"– this is the transition of a ground fault. Most often it occurs when a specific voltage is biased (more than 5 V) in the electrical module line. To eliminate this error, you need to check the voltage level between the 3rd pin CN3 of the electrical module and the line when grounded. You will need to ensure the quality of the cable coating.

Error "43"– a critically reduced level of coolant temperature and a decrease in pressure to almost 0. You can try to power the product through a water tap until the required pressure level is obtained and try to turn on the boiler again.

Error "16"– lack of coolant. To resolve this problem, check for water in the system.

Error "99"– impossibility of removing exhaust gases. Most often this happens due to a broken hood fan. To fix this problem, it is best to contact the service immediately. There, specialists will clean the fan itself, as well as the entire heat exchanger.

Rinnai brand gas units are the highest quality equipment with excellent performance for residential and industrial buildings. When replacing injectors, you can use liquefied gas, which is very popular among many owners country houses, near which there is no main gas. The original control system will allow you to adjust the necessary modes and set the necessary programs in a matter of seconds. Reviews from boiler owners are entirely positive. It is best to carry out repairs and servicing of products only in service centers, spare parts can be ordered there without any problems.
