Unveiling the Hidden Dangers: Why do gas stoves need to be vented

Why do gas stoves need to be vented?

You’re really getting things done efficiently now that you’re cooking with gas! Did you know that about 40% of American homes also use gas for cooking? If you have a range hood installed, make sure to keep it on while cooking to vent out fumes and pollutants, just like the Center for Disease Control recommends.

Regrettably, a large number of individuals are not informed about this, possibly due to the fact that a gas range is not required to have ventilation. In most homes across the United States where gas is used for cooking, ventilation for the range is not necessary. Nevertheless, just because it’s not mandatory doesn’t mean it’s not advisable. If you have a commercial-style range, ventilation will be necessary. It’s always a good idea to check local regulations and guidelines to make sure you’re complying with the law.

Downside of Non-Vented Gas Ranges

Although a correctly installed gas range in a home is generally deemed safe, it is crucial to exercise additional caution. Currently, there is no universally accepted standard for carbon monoxide levels in indoor air. Nevertheless, research indicates that homes without gas ranges typically have carbon monoxide levels ranging from 0.5 to 5 ppm. In homes with properly calibrated gas ranges, this level increases to 5 to 15 ppm. However, in the case of gas ranges that are poorly adjusted, the carbon monoxide level can reach 30 ppm or even higher.

A joint research project revealed that gas stoves in residential settings can emit high levels of harmful pollutants, leading to a decline in indoor air quality and posing health hazards. These pollutants consist of carbon monoxide, nitrogen dioxide, and formaldehyde. The study highlighted that gas burners are frequently operated without a vented range hood, significantly raising the risk of dangerous gas accumulation.

The primary objective of this study was to assess the impact of gas cooking across different seasons on exposure to these harmful substances. The researchers observed that individuals residing in households lacking a vented range hood were consistently exposed to unacceptable levels of pollutants, surpassing the thresholds set by health standards.

Gas ranges are highly favored due to their affordability and the ability to quickly regulate heat. They effectively utilize natural gas, yet it is important to acknowledge that the absence of a vented range hood does not eliminate the potential health hazards associated with operating a gas range.

How to vent your range hood

A ducted range hood is the optimal choice for providing top-notch ventilation for a gas range. While there are alternative options available, the most effective range hood solution involves ducting that directs air outdoors. Although there is a diverse selection of ductless range hoods on the market, these units primarily focus on filtering out odors, grease, chemicals, and dirt.

For those seeking to maintain the highest indoor air quality possible, a ducted range hood is essential. The frequency of your cooking, the level of grease in your meals, or the intensity of odors produced all determine the workload required of your hood. When it comes to performance, nothing surpasses the efficiency of a ducted range hood.

Burning natural gas appliances can generate harmful waste that poses health risks. Carbon monoxide, a colorless gas, can be absorbed by your bloodstream faster than oxygen. The CDC reports that more than 400 Americans perish annually due to carbon monoxide poisoning, while an additional 50,000 seek medical attention for the same reason.

It is crucial not to underestimate the dangers. To mitigate risks, consider installing alarms, ventilating by opening windows, and utilizing the exhaust fan on your range hood during cooking.

Regardless of whether you own a gas or electric stove, a range hood is a dependable choice for maintaining clean and fresh air in your kitchen.

Minimize bad odors of food

Cooking odors can accumulate rapidly in a poorly ventilated residence, persisting in your kitchen for extended periods, possibly even weeks.

However, a range hood serves the dual purpose of eliminating hazardous pollutants such as carbon monoxide and effectively getting rid of cooking odors from your kitchen space.

Is it secure to possess a gas stove without proper ventilation?

Having a gas stove without a vent is not safe. While vent hoods are not mandatory in the United States, they play a vital role in enhancing the quality of indoor air. Considering that Americans spend the majority of their time indoors, it becomes even more crucial to expel pollutants and cooking exhaust. According to the Environmental Protection Agency (EPA), certain pollutants can be 2 to 5 times more prevalent indoors than outdoors.

Therefore, it is advisable to always turn on the range hood when using your gas range. If you are cooking at high heat or for an extended period, using the maximum speed setting is recommended. However, for regular cooking, the low speeds of the vent hood are more than sufficient.

Gas Stove Safety Measures to Minimize Risks

Safety is of utmost importance when dealing with gas stoves. Always ensure that the knobs are fully turned off when not in use to prevent potential gas leaks. Additionally, it is crucial to have a carbon monoxide detector near or inside your kitchen and to test it annually.

Remember to promptly replace the batteries if the detector signals low battery power. To protect your family from harmful compounds while using the stove, proper ventilation is essential.

1. Exhaust fan for a gas stove

Gas ranges are known for generating significant amounts of heat and emitting small amounts of harmful chemicals. To ensure the well-being of you and your family, it is crucial to have an exhaust fan installed. We highly recommend opting for a vent hood with a minimum of 600 CFM (Cubic Feet per Minute) to effectively remove any pollutants from the air when using a gas stove.

However, there may be instances where you require even more ventilation. To determine the minimum CFM needed for your vent hood over a gas stove, simply divide the total BTUs (British Thermal Units) by 100. For optimal ventilation and efficiency, it is advisable to invest in a range hood with at least the calculated CFM value.

2. Hoods and Fans

Many gas-powered homes are equipped with hoods or fans above their gas stoves. However, studies have indicated that a significant number of home cooks with these hoods or fans either use them infrequently or not at all. If you happen to have a hood or fan over your gas stove, it is advisable to consistently utilize it every time you cook.

It is worth noting that building regulations do not mandate residential gas stoves to be vented outdoors. Nevertheless, if you are in the market for a stove hood, CUB suggests opting for one that has the capability to vent outside your home.

If you are unsure whether your current stove hood vents outdoors, you can inspect for a duct. Take a look at the cabinets above your stove to see if there is a duct present (look for a silver tube). In the case of a single-family home, it is recommended to locate the end of the duct to ensure that it is venting all the way outside and not terminating in your attic. It is important to note that most multifamily housing does not possess this type of kitchen ducted ventilation.

3. Airflow From Windows and Fans

Regrettably, Oregon does not provide any rebates or incentives for the acquisition of range hoods. Consequently, many customers find themselves unable to afford the expenses associated with purchasing and installing one. Additionally, numerous individuals reside in residences where the layout of the home or the landlord’s regulations prohibit the installation of an outdoor venting hood.

Nevertheless, even if your home lacks an outdoor venting stove hood, it is mandatory to have some form of ventilation in all kitchens according to Oregon Building Codes. No exceptions are made in this regard. In the absence of mechanical ventilation, such as an outdoor venting hood, a window that can be opened must be present in the kitchen.

If the installation of an outdoor venting hood above your stove is not feasible, it becomes crucial to properly ventilate your kitchen by opening windows. In the event that your kitchen does not have windows that can be opened, it signifies that your home does not comply with the established codes and necessitates updating.

A vented range hood can greatly enhance your cooking experience, making it more enjoyable and satisfying.
