A ducted stove hood provides enough ventilation for a gas stove. Of course, there are other possibilities, but the most efficient stove hood option necessitates ducting that vents outdoors.

There are many different types of ductless stove hoods available, but they all filter smells, grease, chemicals, and dirt. A ducted stove hood is what you need if you want to maintain your interior air quality as pure as possible.

The more you cook, the greasier or more odorous your foods are… the harder your hood must work. Nothing will do more to help you than a ducted stove hood.

Any device that uses natural gas generates waste that might be harmful to your health. Carbon monoxide has no odor and is absorbed by your circulation faster than oxygen. 

According to the CDC, about 400 Americans die each year as a result of carbon monoxide poisoning, with an additional 50,000 being treated in hospitals. It’s not something to take chances with. While cooking, you should set alarms, open windows, and turn on the exhaust fan on the stove hood.

Gas Stoves And Carbon Monoxide

Appliances that use natural gas to generate trash that might be harmful to your health. Carbon monoxide is a colorless, odorless gas that enters the circulation faster than oxygen. As a result, it may easily overpower someone who is ignorant of the presence of the vapors.

Nausea, weariness, chest pain, and bewilderment are some of the symptoms. Even if the stove is working correctly, persons with allergies or other respiratory disorders may suffer significant health repercussions from tiny amounts of harmful vapors.

To decrease fumes from gas stoves, open windows slightly to allow a stream of pure air to circulate. Install carbon monoxide detectors in your home as well to warn you of any fume concerns that may come from the use of gas burners and other equipment.

Do you Need Stove Hood For A Gas Stove?

Yes! If you have a gas stove, you must ensure that the stove hood is properly ventilated. Cooking on your stovetop may emit a lot of contaminants into the air, depending on your cooking method. A port gas stove, for example, is necessary if you do a lot of cooking or frying at high heat in a wok.

In this section, we will go over all of the reasons why a full stove hood is required for a gas stove.

Safety:

The majority of gas flames emit carbon dioxide. Incomplete combustion produces carbon and carbon dioxide, but it takes a long time to produce incomplete combustion and byproducts. 

Nitrogen dioxide levels that are too high cause respiratory difficulties such as asthma flare-ups and irritation. This is a valid issue, especially if you have children.

Because gas stoves burn relatively cleanly, they do not need venting up to electric fields. However, keep in mind that venting is utilized to remove smoke, heat, steam, and dirt – as well as the byproducts of burning gas.

If you’re used to cooking with high heat, a skillet, frying meats, bacon, and so on, all of these goods generate smoke that steams up your windows and leaves filth in your cupboards, as well as odors that may linger for days. Venting is a specialized way for preventing any of this from happening.

It’s just the nature of cooking in which particles and compounds are released into the environment. These aren’t items you should keep on your property, whether they’re harmful or not. 

Proper venting is the easiest method to proactively address the issue so that it does not become a problem later on.

Cleanliness and Odor:

Many individuals are unaware of how critical it is to port whether you’re using an electric or gas stove. 

When something is draining, the bulk of us just turn on the dock. We consider this ventilation to be superfluous.

When we cook meals in a skillet or pot, however, particles of smoke, water, oil, and food are released into the environment. These particles have a tendency to settle everywhere. 

Dirt will begin to appear on furniture, upholstery, and carpets over time. Grime can wreak havoc on your property’s finishes and surfaces.

Furthermore, the dirt from all of the distributed particles emits an odor over time. If you don’t port when using a gas stove, you’ll end up with a beautiful house with a musty odor.

This is especially true of the open theory floor designs that are so fashionable these days. 

If you have an open floorplan or a loft-style home, culinary odors have a tendency to permeate throughout the entire house.

Health:

There’s also the issue of health. Venting is critical because every time you cook or sear something in a pan, ultra-fine particles are released into the atmosphere.

These aren’t typical particles; they interact with other chemicals in the environment (sometimes produced in the air fresheners, air conditioning system, along with other substances in the atmosphere).

They also have a significantly contaminated chemical that is unsafe to breathe indoors.

The essential thing is that you are not expected to be exposed to numerous toxins and impurities emitted by the gas stove. 

Working amid such stoves without a sufficient vent that keeps those substances from soaking into your interior environment is not beneficial.

Dangers of Non Vented Gas Stoves

While a correctly built home gas stove is deemed safe, research has indicated that extra measures should be taken. There is currently no agreed-upon carbon monoxide standard for indoor air. 

However, the typical amount in non-gas stove houses ranges from 0.5 to 5 ppm. This figure rises to 5 to 15 ppm in households with adequately calibrated gas stoves, and it can reach 30 ppm or more in homes with badly adjusted gas stoves.

According to a joint study, domestic gas stoves can emit significant quantities of pollutants that severely influence indoor air quality, increasing health hazards.

 Carbon monoxide, nitrogen dioxide, and formaldehyde are examples of contaminants. 

According to the study, gas burners are frequently used without the assistance of a vented stove hood, which dramatically raises the danger of lethal gas accumulation. 

The purpose of this study was to assess the effect of cooking with gas throughout different seasons on exposure to these hazardous pollutants. 

The researchers discovered that persons living in houses without a vented stove hood were consistently exposed to harmful pollution levels, which surpassed what is considered acceptable by health recommendations.

Gas stoves are popular because they are inexpensive and allow you to quickly regulate the heat. They effectively burn natural gas, but these advantages do not outweigh the possible health concerns of using a gas stove without a vented stove hood.

WHY DO GAS STOVES NEED TO BE VENTILATED?

There are various reasons why a suitable vent is required for a gas stove stove. This is important not just for the air quality in your house, but also for your safety and health.

There are also serious difficulties that might arise as a result of messes in your kitchen. In this part, we will look at these concerns.

 

How much CFM are required to exhaust a gas stove?

Every gas stove is unique, but determining how much CFM you want is simple. Simply divide the total number of British thermal units by 100. Check the owner’s handbook if you can’t locate the BTUs. Most items now have manuals that may be found online or by calling the manufacturer.

Check out this video to learn how to calculate the CFM required for your hood.

 

Most households will be able to vent a 30″ or 36″ gas stove with 900 CFM. Larger stoves measuring 42″, 48″, 54″, or 60″ may necessitate 1200 to 2000 CFM.

We’ve posted detailed assessments of various hoods with varying CFM levels. Take a look at them below.

Can I use my gas stove with a ductless stove hood?

We do not advocate using a ductless hood to vent your gas stove. A ductless stove hood simply recirculates the air in your kitchen. The air enters your hood, passes through charcoal filters, and returns to the kitchen.

Many of the ultra-fine particles that are detrimental to your health cannot be removed by a ductless stove hood. Furthermore, it is often not as powerful as a ducted hood. So, to keep your interior air pure and fresh, utilize a ducted hood.

Can I use my gas stove with a downdraft stove hood?

Yes, however it isn’t as effective as a hood over your stove. Downdraft hoods draw air downward before directing it to the exterior of your property. They had to exert more energy and combat the growing cooking smells to get them to depart. In contrast, over-the-stove vent hoods absorb all naturally rising air.

With hoods over gas stoves, efficiency is especially crucial. They emit hazardous toxins that must be removed from your house. Among these compounds are carbon monoxide and dioxide.

Is a makeup air kit required in a kitchen with a gas stove?

Most of the time, you won’t need to utilize make-up air. If your stove hood has a CFM rating of 1200 or more and you use it for several hours every day, you may require a makeup air kit. 

If you have a hood over a gas stove in a tiny kitchen, you may also require a kit. Because small kitchens have less air volume, make up air does not require much power.

In addition, certain building rules mandate that your stove hood have make-up air. To double-check, consult your state’s codes or contact your landlord.

You can also ask a contractor if you’re unsure whether you need make-up air.

How high should a stove hood be installed over a gas stove?

Install a stove hood between 28 and 36″ over a gas stove. This prevents damage to your hood and enhances its performance. Mount your hood between 36″ and 42″ above the stove on an outdoor barbecue. This compensates for the additional heat and smoke generated by your grill.

Is carbon monoxide produced by gas stoves?

Yes, among other toxins, gas stoves emit carbon monoxide, carbon dioxide, and formaldehyde. These substances are hazardous to your health in excessive doses. A carbon monoxide detector should be installed in every home that has a fuel-burning equipment, such as a gas stove. If it frequently goes off, you know you need to enhance your ventilation or use the stove less.

How much carbon monoxide is produced by a gas stove?

A gas stove’s CO levels are typically between 5 and 50 ppm. Gas stoves may emit hundreds of ppm of carbon monoxide when left on for lengthy periods of time, far beyond the permissible levels in your house. CO levels might rise as a result of poor ventilation.

The Occupational Health and Safety Administration limits employees’  CO exposure to 50 parts per million (ppm) for an 8-hour period. Other firms have established exposure limits of 25 ppm and 35 ppm during the same time period, which you can see here.

According to the EPA, there is no common standard for indoor air quality beyond the aforementioned rules for employees. However, the limit for outdoor air is 9 ppm after 8 hours and 35 ppm after 1 hour.

What are the hazards of carbon monoxide?

Long-term CO exposure of at least 50 ppm can deprive your body of oxygen. Minor symptoms such as headaches, dizziness, nausea, and shortness of breath might result. However, in severe circumstances, CO might cause you to lose consciousness or reach your heart or lungs, which can be deadly.

Carbon monoxide is especially hazardous to persons who are asleep. You might be exposed for 8-10 hours or more without realizing it, which is hazardous to your health.

Is carbon monoxide rising or falling?

Carbon monoxide rises together with the surrounding air. However, this does not exclude it from being found in low-lying areas. Because carbon monoxide is only slightly lighter than air, the weight difference isn’t significant.

Because carbon monoxide rises, the EPA suggests placing your CO detector approximately five feet above ground. Closer to the ceiling is also OK, but do not place one within 15 feet of a gas-burning device.

Is it possible for a stove to set off a carbon monoxide detector?

Yes. Leaving a stove or stove on is the most typical way to set off a carbon monoxide detector. In addition, if you burn, spill, or boil your meal, the CO detector may go off. If the CO detector is close to the stove, it may also detect lower quantities of CO than typical.

Is it possible to use a microwave over a gas stove?

Yes, you may use a microwave over a gas burner, which is known as an OTR microwave. A stove hood, on the other hand, is a preferable solution for improving ventilation. Over-the-stove microwaves typically have a maximum airflow of 400 CFM. Professional stove hoods for your house, on the other hand, suck between 600 and 2000 CFM of air.

What happens if you leave the gas stove on?

When you leave a gas burner on, hazardous particles build up in your house. Carbon monoxide, carbon dioxide, and formaldehyde are a few examples. Carbon monoxide is the most harmful since it has no odor or color.

If you left your gas stove on, immediately open all windows and doors to enhance airflow. Turn off the burner immediately and avoid using any electrical equipment. A spark may ignite the gas, which would be extremely deadly.

If the gas smell is really strong, get everyone out of the home for a few minutes to let it air out. This might help to avoid CO poisoning or respiratory problems.

You should get a CO detector if you don’t already have one. It will ensure that the carbon monoxide levels in your house remain safe. They’re especially useful if you don’t notice you’ve left a stove or your stove on.

Avoid using your stove to heat your home to increase ventilation. Leaving it on for extended periods of time can result in deadly quantities of carbon monoxide emissions.
