10 Reasons Why Gas Stoves Need To Be Vented

Do gas stoves need to be ventilated?

When buying a new stove it is always important to make sure it is set up properly. In some cases, installation may require a professional. One of the things to consider is whether or not you should ventilate the stove.


When to ventilate? While some models are designed for use without ventilation, most stoves require good ventilation. In many cases, a ventilation system may be required by local laws and building codes. If you are unsure of your local codes, please contact your retailer or installer.

You may want ventilation if:

  1. The kitchen has no windows. Without windows, you need ventilation so that steam and odors can escape the room.
  2. You have an open kitchen and living room. In areas where the kitchen is open to other rooms in the house, you’ll want a ventilation system that removes smoke and fumes from the rest of the house.
  3. The kitchen is part of a common area in an apartment complex or condominium. You want ventilation so smoke and fumes don’t spread through shared areas or common ducts or vents.

10 reasons why gas stoves should be ventilated

Gas stoves are a wonderful addition to the kitchen, but must be ventilated. If you don’t have an extractor hood, or if it isn’t strong enough, here are 10 reasons why gas stoves should be vented.

1. The smell of food can be removed from the kitchen, home and clothes

The smell of cooking onions can be delicious, but if it lingers in the house for days, it becomes annoying. An extractor hood can help remove cooking odors from the home so you can enjoy your meal without the lingering smell of onions, garlic, and other foods that tend to linger long after dinner.

2. Smoke and grease can be removed from the kitchen

Cooking on a gas stove produces smoke and grease that can settle on your walls and ceiling, making them look dull and dingy. If they build up too much, they can also become a fire hazard. Removing smoke and grease with an extractor hood keeps your kitchen looking fresh and clean

3. Range hoods improve indoor air quality by removing pollutants

Unless you’re using an outdoor grill, gas cooking produces pollutants in your home’s air. Over time, these pollutants can cause symptoms such as headaches and sinus congestion for people who are sensitive to them or who have allergies or asthma.

4. To Prevent Carbon Monoxide Poisoning

The most obvious reason to vent your gas stove is that it helps prevent carbon monoxide poisoning. When natural gas burns, it produces carbon dioxide as a by-product. This invisible, odorless gas can build up in an unventilated kitchen or home and make you very sick.

Symptoms of mild carbon monoxide poisoning include headache, dizziness, and shortness of breath; more severe poisoning can lead to death from loss of consciousness and failure of the heart and lungs.

5. A properly installed range hood over your range will help keep the area around the stove cleaner

An extractor hood not only removes cooking smells from the air, but also removes much of the grease that would otherwise end up on cupboards, walls and other surfaces above your hob.

6. Cooking at higher temperatures

With a vented hood, you can cook at higher temperatures without worrying about burns or smoke alarms when cooking foods that produce a lot of smoke, such as bacon or burgers, at high temperatures.

7. Venting extends the life of your gas stove

By removing the heat build-up and moisture around the burners on the top of the cooker and the flames on a conventional oven. Maintaining an even temperature prevents parts from failing faster than they should.

8. It makes cooking easier

It’s easier to see what you’re cooking if you have decent lighting over your hob, which is not possible with venting. It’s also easier to get rid of those pesky fumes caused by food splashing on the heat source.

9. It gives you better cooking results

If you have trouble seeing what you’re cooking and don’t want to open windows or turn on fans, you can install an exhaust system that pulls air down and out instead of up through an extractor hood. This pulls air over food being cooked which can improve flavor and result in better tasting food!

10. Venting reduces the amount of moisture in the air around your stove.

This will help reduce grease build-up and rust on your stove burners and in your oven. Ventilation removes heat from around your burners on top of your stove and from inside your oven cavity. This keeps your kitchen cooler by removing the heat generated by cooking away from the kitchen.

11. Ventilation prevents stains on walls and ceilings

Properly installed ventilation will channel moisture and stains up and away from your walls and ceilings, so you don’t end up with unsightly water spots on your wall or ceiling. Condensation that is not properly ventilated can cause paint to peel, plaster cracks, stains on ceilings and walls, as well as mold and mildew growth.

12. Ventilation Makes Your Stove Safer

While there are no strict regulations on how to install a gas stove, there are certain safety standards that must be met. All approved gas appliances must have good ventilation.

A gas flame needs air to burn properly, and if not enough air comes in from outside the room, the flame will start drawing oxygen from the house. This can cause carbon monoxide poisoning and also be a fire hazard. For more on CO poisoning see this link warning signs of CO poisoning.

13. Ventilation prevents backdrafts

When there is insufficient combustion air in the room, backdrafts can occur. This happens when warm air goes up the chimney and is replaced by cold air coming up the chimney (or up the chimney pipe if you don’t have one). This creates a siphon effect in which more air is sucked out of the house than comes in.

14. Venting removes heat from your kitchen.

When you’re cooking on a hot summer’s day, the last thing you want is to heat up an already hot room even more!

In summary, most gas stoves today are sealed and do not require venting. However, it is always good to consult the owner’s manual of your stove or the manufacturer. You can also see if your stove has a venting system by looking at the back of the unit. If it does have a venting system, you’ll see a vent panel from which the heat and smoke can escape.

If your stove requires ventilation, be sure to use the correct stove vent materials for installation. You must also follow all building codes for proper installation of your ventilation system.
