Duct Heater Hi, I have recently had my Omega ducted heater serviced and I have been advised by the technician that he found traces of carbon monoxide in my home 1-2 points on his testing devices. Is this dangerous and do I need to replace my heater unit. Technician advised me that 10 p.p.m is harmful and dangerous! Cheers Tass

Carbon monoxide in any concentration is deadly. It gets in the blood and prevents the blood from absorbing oxygen. Follow the technicians advice and find out why there is this gas in the house.10 ppm is easily achievable and you cannot smell it and won't know it until you feel sleepy

SOURCE: Dy/night heater turns on for 10 sec then and off, over and over

Hi and welcome to FixYa,

If I understand your concern, it is that the heater switches itself on for 10 seconds and then switches itself automatically off. A couple of ideas of you may want to explore/check:

  1. the built-in protection system detects an internal fault and to prevent any further damage switches itself off;
  2. the faults could be:
  • open heating element (assuming it is electrical);
  • blower not turning;
  • open limit switch. The limit switch is an inline cutoff to the heater that automatically opens up when the heater exceeds a pre-determined temperature independent of the settings in the thermostat. This is like a thermal fuse once gone bad will remain open;
  • whereas a thermostatic switch will turn on if temperature is below its threshold and turn off if the temperature is above. It is basically an on/off switch.
Often the limit switch would look like the image below.

To be able to provide a more detailed information/assistance, pls verify & post back the model number of the Day Night Heater. Model 8ou-19 does not turn up anything. Or perhaps you can share the website you were referring to.

Good luck and Thank you for using FixYa. Happy Holidays.

Fumes are bad, stop using it until a technician has checked it out. Get a CO detector!

What makes a ventless gas heater put out carbon monoxide fumes


Any gas appliance that burns gas puts out Carbon Monoxide. The trick is to make it not too much, however, how much is too much. Read this;

http://www.ventfree.org/content/view/42/18/

and there are warnings here too;

https://www.angieslist.com/articles/are-ventless-fireplaces-safe.htm

and a list of the potentially dangerous gases they omit;

https://www.abe.iastate.edu/extension-and-outreach/carbon-monoxide-poisoning-unvented-gas-space-heating-appliances-aen-204/

I would not use one unless I had good ventilatioon and a better Carbon Monoxide alarm.

Tip

Carbon Monoxide and Heating Systems


Every year there are many deaths that could be avoided by a few simple checks, or the addition of a carbon monoxide detector in the home. The worst thing is that many of those people will have never known that they were under attack by a silent killer.

One of the products of the combustion of any fuel is carbon monoxide gas. The concentration of this gas can vary greatly depending on how complete the combustion process is. Many heating systems will check the combustion process and shut themselves down if the flame becomes too unstable and begins to produce harmful gases. There also are many heating systems still in service that do not check and will produce carbon monoxide gases. If carbon monoxide gas can get into your living environment then you and your family could be at risk.

To reduce the risk of carbon monoxide gas affecting your home, you should have your furnace checked every year. Make sure that the venting system of the furnace or boiler is in good condition. Make sure that the safety controls work properly and are not bypassed. Never bypass the safety controls to get heat even temporarily. Make sure that if you are using an unvented appliance in your home that you follow the instructions by opening a window a bit to give the heater fresh air. Many of these appliances have a oxygen sensor in them to protect you. Make sure to clean this device yearly and if the heater keeps going out and you don't know why, it could be because of oxygen depletion in the room.

Plugged chimneys, bad vent piping, wrong gas pressures, faulty, dirty burners, and many other things can cause carbon monoxide to build up in your home. Be careful to have all of these things checked often. If you heating system is not acting right then you need to have it checked immediately.

One of your best defenses against carbon monoxide is a detector. I like the ones that actually give you a digital read out of the level of the harmful gas in your home. You will find that even your gas range or oven will produce carbon monoxide and it is helpful to see when even low levels occur. The other reason is because the detectors that only give a warning on high levels will often not warn you till the gas reaches deadly levels. You want to be aware of these levels long before the reach deadly levels. This gives you time to get a problem identified and fixed. Also time to evacuate if necessary.

For best peace of mind, spend the money to buy a good quality carbon monoxide detector and then make sure you get it out of the bag and install it. Get your heating system serviced by a professional that can check the combustion process to make sure your heating system is burning cleanly and efficiently. By doing a few simple things you can protect yourself and the ones you love.

How do you remove the heater floor duct that takes heat from the heater to the rear seat? Do you have to remove the floor mat, and if so, how is that done?


Take out the front seats and console(if equipped) to access the ducts under the carpet. Heater core is a 5 hour job for trained technicians.
Once the seats are out, remove the sill plates and maybe even the rear seat for access.
Many people cut the ducts and use duct tape to reinstall.

Wow! Actual use for duct tape, as intended!

None of these products are used INSIDE the heat exchanger. If the problem is a cracked heat exchanger, you may be able tp purchase replacement parts to repair it

How to Fix Cracked Furnace Heat Exchanger DoItYourself com


The heat exchanger must be free of cracks and holes due to the potential of carbon monoxide leakage. You can probably make a short term repair with sheet metal and high heat furnace refractory cement, but that is a quick fix only.
Please be aware of the potential for a lethal situation due to carbon monoxide poisoning.

Are radon and carbon monoxide detectors the same?


A carbon monoxide detector is a device that detects the presence of carbon monoxide gas to prevent CO poisoning. Radon is a different gas that can enter your house through foundation cracks. It has its own test kit to detect traces.

Pilot light on Intertherm MG 075A furnace will not stay lite on windy days. Worked fine for 20 years but has been a problem the last couple of winters. thermocoupler has been replaced a couple of ti


If this really is a thermocouple unit with a standing pilot, it must be pre 1978, I would suspect a crack in the exchanger first off as thats potentially lethal, not a joke, many heart attacks, headaches, fibromyalgia etc comes from undiagosed carbon monoxide exposures!
And many die from it sadly as it is 100% preventable, a detector would be advised even if you are ok there. A draft can be from the roof car ruting out or misssing? any dryer, Jennair, bath fan, water heater, stove top and many hvac systems create negative pressure in the home by exhausting air and not returning any or less than removed, as in a leaky supply duct leaking in the attic, the furnace pulls X cfm and returns Z
and fireplaces etc will backdraft. gas valves do get tired too.

Is there any possibility my Rinnai econoheat850 gas heater can give off carbon monoxide?


Any time there is combustion of any type fuel, from a Rinnai heater to a car engine. There is always a small amount of Carbon Monoxide given off. But, it's usually in small insignificant amounts.

Since your model is a Vent-free or flue-less model, the chances are a little higher. This usually occurs if the heater has not been properly and regularly maintained. Keep in mind, flue-less heaters take in household air for combustion, heat it and send it back out. Whatever is floating in the household air (duct, lint, pet hair, etc) is pulled into the heater. These things can clog the burner(s), the pilot and the Oxygen Depletion Sensor (ODS) and cause incomplete combustion. Which translates into higher than normal Co levels. However, your unit is equipped with an ODS, that will shut the gas off to the heater, if the household oxygen level reaches 25%. Which is not the danger level, which is 19%. Once the Oxygen level returns to 30%, the ODS will release the gas valve and gas will return to the pilot, so that you can relight it.

When properly maintained and operated according to the Owners Manual (see link below) they are totally safe. In the last 20 years, millions of vent-free/flue-less heaters have been sold and operated throughout the world. There has never been a death related to their use.

Certainly, if you or your family think you are experiencing signs of carbon monoxide poisoning, stop using the heater and have a qualified Rinnai technician check and service the heater. If you have other gas appliances in the house, it may be one of them causing the symptoms and not the heater. You may want to have those check and serviced, too.
