Carbon Monoxide Alarm Sensor 60ppm: Termet Gas Stove, Ventilation Steps, 0 ppm After Venting

Hello,
This morning I was awakened by a carbon monoxide detector, an alarm went off and the display showed a value of 60ppm. I took some steps to remedy this, I ventilated the flat, after a while, the detector showed 0 ppm. The termet gas stove was not turned on. The last use of the stove took place in the evening. I will just add that the stove has important reviews, the sensor also. I am concerned about this situation, could somebody help?

Nobody will help you on the forum, because each case is individual and requires a local vision.

The base is adequately good ventilation and, ideally like fresh air, it flies in "clean" rooms like rooms, and the "dirty" air goes out with exhaust grilles in the "dirty" rooms like the kitchen, bathroom, etc.
With poor ventilation, you can have backdoors and supply of sludge through these exhaust grilles and through the exhaust ducts.
The sources of carbon monoxide may be with you, but in the case of multi-family buildings also with your neighbor.
It may be helpful to know where your carbon monoxide detector is. In general, it is worth having such a sensor in rooms where you have gas appliances and in rooms where households usually stay / sleep.
Call a professional and let him check the chimney draft. You can try yourself with a flip-flop of toilet paper to check whether the grille is exhausting or maybe blown.
You may have to install a window ventilator if you have too tight doors and windows, because the lack of proper ventilation can disrupt the gravity ventilation. If you live on the top floor, you have short chimney ducts, which may even weaken the effect of gravity ventilation, and in the case of backflow you can suck in roof sludges, etc. There are some options and options to choose from, and you might have missed something important, so do not look for help on the forum but with a specialist if you do not know what and how to check.

Sometimes, even with efficient gravity ventilation, there can be a backflow in strong wind, so sometimes it can be a one-time alarm but you can never ignore it and you have to make sure that the gravitational ventilation is working for you, or it can barely bite and alarms are in your place undesirable standard.

Ventilation control was some months ago and everything was ok. The alarm happened for the first time hence my concern. The stove and sensor are in the bathroom.

The control shows the status at a given moment, and the conditions can change.
Alarm for the first time since when? Have you got a sensor for several years?

When writing a stove, I understand that it is a gas term for instantaneous heating of domestic hot water
Do you have any other devices that could emit fumes as a result of combustion?
If you used the terma in the evening, and the sensor gave an alarm only in the morning, it is rather not an alarm for your "stove", although different miracles may be happening.
You could get a dose of rock from a neighbor who has a gas boiler in the bathroom, for example.
Glue yourself over the bathroom exhaust grate over the toilet paper and check periodically whether the flap is attracted to the grille (yes it should be) or maybe it is sometimes repelled, which means that you have a backflow and a "dirty" air from the ventilation duct in which bacteria are flying and maybe a chad from a neighbor.
Use the same simultaneous test with a toilet paper leaf in the kitchen. Observe the leaves cyclically, especially shortly before and when your gas-burning devices are working and shortly after finishing their work. Mount the leaves so as to maintain the free flow of air, that is, ventilation, so that they are not a blocker stopping the operation of gravity ventilation.
Pay more attention to the cyclical airing of the apartment and can buy another carbon monoxide sensor into the kitchen and the room where you are staying and sleeping.

I would add that it is worth to make ventilation slots in the door near the floor, so even if you have a closed door you have ventilation, i.e. by opening the window in the room, fresh air flows calmly into the bathroom / kitchen and out there. Doors from the bathroom / kitchen should have ventilation holes / apertures as I remember well. 220 cm2, the room is recommended min. 80 cm2. If you have a transitive room, then it is worth giving at least 2x a larger hole / aperture so that the aperture allows free passage of air from both rooms.

The detector can attach to various things (depending on the type of sensor used).
Some detectors are able to react even to humidity or pressure. Deodorants, hairsprays and other rubbish in the air are standard.

A good sign that something was there was that the detector showed value, and after ventilation it was not possible, which means it works as well.
It is worth checking the detector in the service using the reference gas (any sprays and other crap you can forgive because they do not give meaningful readings).
The question of what was the reason may be difficult to determine.

Just like a colleague mentioned, even if you did not use the boiler yourself, there were cases where flue gases from another chimney due to atmospheric conditions or poorly working ventilation were getting through a chimney or ventilation ducts.

There was an accident where the object did not even have this type of heating, but the ventilation drew the exhaust from another object (6 people were impure).

If in doubt, call the Fire Brigade. They have calibrated meters and can measure the level.
(how they have and they can, of course, because there are problems with that)
At present, ambulance services often already have measures.

"Reactions to deodorants, hairsprays and other rubbish in the air are standard."

They are not a standard - this is how the high-quality detectors with a semiconductor sensor behave, they do not react with an electrochemical one.
Electrochemicals are insensitive to hydrocarbons.
They are available - eg KIDDE - unfortunately, the price is a little higher.

In the case of backflow of gas from a neighbor, such a number may occur - especially in high-rise buildings. For tight windows.

When I bought the highest Kidde model, it cost about PLN 150, I also have a sensor from another company, which cost about PLN 180.
In theory, they last up to 10 years, so it can be treated as an investment for years, and considering that it is bought for protection or saving life, not as a gadget licking their own ego, this expenditure is small.

In my opinion, the window should be tight in principle, so there are no windows that are too tight. However, if, after replacing the window and door carpentry, there is no adequate gravity ventilation, then wall or window diffusers are used. The issue of additional diffusers does not apply to those who have mechanical ventilation.

Today at 8 am the situation repeated itself. Again the alarm and again 60ppm. All the family members still slept so nobody in the apartment used anything. Papers on ventilation grilles have been installed and so far the air sucks, so it's ok. The apartment has been rented since September and has been alive in it since then, the sensor was purchased along with the move. Doors in the bathroom and other rooms are not too tight, there are visible gaps. The flat is on the 4th floor and the block is 10 floors. I will just add that in the beginning there were problems with the stove, often it did not fire. Thanks for the tips.

Buddy "eightk" you are right, but unfortunately only a little.
Indeed, electrochemical sensors are more selective, but you are not right that they do not work on hydrocarbons. Electrochemical sensors are very sensitive to some hydrocarbons (eg acetylene), and in fact not very sensitive, eg to methane or propane. Also be careful with advertising specific "resistant to everything" products.
Also, you are right, for example in the bathroom where you use a deodorant, whose carrier is propane-butane, then the electrochemical sensor will be less susceptible. However, especially some hairsprays can have different rubbish in them and it's not so colorful anymore. I do not remember how acetone (a component of many nail polishes), but also quite some sensations reacted quite well. Some react very strongly to ethanol. It all depends on the sensor and how it was built.

Buddy "eight" with sealed windows you would not have "back". A bit of physics. The "back" you are talking about is the inverse of air due to the difference in air density or mechanical suction. In the case of differences in air density, it is a matter of atmospheric conditions, and in the case of aspiration the point is that a working boiler, in the absence of air supply (eg tightly closed windows and air vents) sucks in the air from the ventilation duct. You would be right, but your colleague clearly wrote to you that the boiler was not working.
So the reason for the reverse thrust could be atmospheric conditions. But in order for them to have an impact, it must be a sequence of air - entrance and exit (only the reverse), ie windows can not be too tight. I think ventilation colleagues can explain this to you more widely.
Alternatively, I recommend: http://wentylacja.org.pl/pages-67.html

Not the firing of the boiler can be caused, of course, by many reasons, but one of them, as I recall, was the reaction of the decay sensor (if your boiler has one) - please ask in your service. If the situation repeats then I think that you should look for reasons. I do not know how you built the ventilation, but there were cases where, for example, someone connected to the exhaust vent for someone's ventilation, or someone on the common channel mounted a mechanical fan at home, etc..
I would start by checking the sensor on the website and possibly buying another reputable for checking in the meantime. You will always use it later or give it to someone.
You can notify the administration and do a chimney inspection. I suggest so loosely.
If the correct sequence is activated when it turns on, it may actually be a sensor or some trash in the air.
Although I also had the case that a given gas was sucked in by a natural string, and came from the building next door. And every day at 5 am an alarm on the sensors.

Why this bid.
The cofka can be in different situations.
I've seen miracles in the style of a neighbor, who connected the hood with a fan to the ventilation duct, as a result, the tenant on the ground floor had blowing all the muck.
The fact that the "stove" does not work at the author tells us that he does not generate this rock alone, but he gets it as a gift from the outside.
Because it is a flat rented for several months, there may be miracles there, about which the tenant has no idea. Maybe someone once pierced the wall with chimney ducts and there is some leakage that fumes get into the bathroom. Life writes the strangest scenarios.

krzysiek2907, what's your carbon sensor? I am asking because I also had a similar situation in my case and it was exactly 60 units. For no, rational reason. It happened for the first time since 2 years of having a sensor. I note that the chimney sweep was 2 months ago. I'm sure of ventilation (I control it from time to time) and nobody pierced anything at 100%.

"BUCKS" you're right, that's why I am correcting my friend "eight" because he wrote "back" through the tight windows, which can be misleading. He would be right if the boiler worked and forced the withdrawal of air.
Otherwise, if the boiler does not work, then tight windows are an obstacle to the sequence (in any direction).
Of course, the tenant may have other miracles as you wrote and me too. Maybe some other device forces you. It may not be a simple matter at all. But the alarm from the sensor can not be ignored. Normally, I would recommend a visit to the fire brigade or chimney sweep with a certified meter. But if the situation is only for a moment and we do not know when it will happen, it is hard to call them for a moment.
I would just take a second sensor, eg with a different sensor for the equation (just not the market one). Alternatively, if the service is somewhere close, approach to check if the sensor reaction is correct. Then it will be known that the cause is not in the sensor.

as a rule, he was right, because tight windows can disrupt the efficient operation of gravity ventilation but in this particular case it is unlikely, because as you rightly noticed the stove did not work, so there was no active source of potential rock in the apartment.

Domelski wrote:

I have the same sentence, such an alarm is a signal that something may be wrong and it is worth spending some time and a little money on eliminating certain factors.

I have 2 sensors from different manufacturers, one where there is a boiler, and the other one where I sleep in case if, as a result of unfavorable events, I would get a smoke from a gift from the outside. I treated the cost of about PLN 350 as an investment in order to minimize the effects of asphyxiation, so I did not regret it. Tapping the sensors continuously show 0 ppm on the display.

With too tight windows, there can be a backflow as there are at least two ventilation ducts / exhaust fumes / smoke ducts.
The string in each conduit may be different, in which case the conduit with a stronger thrust exhausts the air / exhaust / smoke, and the conduit with weaker thrust introduces air into the room.

In many blocks from the times of the Polish People's Republic and tenement houses you can still find a silly solution in the form of common ventilation and exhaust ducts. Most often they were ventilation ducts as well as flue gas from flow water heaters, where connections were every second storey.

For example, in Częstochowa there are such blocks in the district of Raków, and there as a neighbor two floors lower uses hot water is part of the exhaust from his heater flies into the bathroom two floors higher after which these flue gas out of the ventilation duct of this bathroom. The carbon monoxide sensor in this situation detects concentrations of up to 300 ppm and more. It is similar in many other cities.

It would be good to summon a chimney master (check in the guild whether it is actually a chimney sweeper and not a costume designer) from another city, and commission a specific review. The chimney sweeper should issue a report from the examination of ventilation and exhaust ducts.
An M-chimney sweeper may have connections with the cooperative and then a conflict of interest will arise. In this case, the test may not be reliable.
