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

We don't recommend venting your gas stove with a ductless hood. A ductless range hood merely recirculates your kitchen air. The air moves into your hood through charcoal filters and back into the kitchen. A ductless range hood can't get rid of a lot of the ultra-fine particles that are harmful to your health.

Can a ductless range hood be used for a gas range?

A non ducted or ductless range hood is not the best option for gas stoves because they work by filtering the air inside the hood and returning it into the kitchen. Even if you have a hood with a high CFM rating, charcoal filters will not capture all the gas produced by the stove.

Can you use a recirculating fan with a gas stove?

Generally, recirculating range hoods work well for electric stoves and gas stoves 36” or smaller. With a range over 36”, we don't recommend mounting a recirculating hood since most gas stoves produce too many BTUs for a ductless hood to handle.

Do you need a special range hood for a gas stove?

Do I need a range hood for a gas stove? Yes. Gas stoves produce intense heat and smoke, so you need a kitchen fan that can vent heavy cooking exhaust outside your home. Buy a range hood that is at least 900 CFM to keep your kitchen air clean and fresh.

What kind of vent do you need for a gas stove?

Typically, 400 cubic feet per minute is sufficient for venting an electric stove. The rule of thumb for gas stoves is that the range hood needs to remove 100 cubic feet per minute for every 10,000 BTU's of burner output.

What is a Recirculating Range Hood?- What is a Ductless Range Hood?

Why does a gas stove not need to be vented?

These pollutants include carbon monoxide, nitrogen dioxide, and formaldehyde. The study found that gas burners are often used without the support of a vented range hood and this greatly increases the risk of deadly gas buildup.

How do I vent my stove without a hood?

Do range hoods have to be vented outside?

Do range hoods have to be vented outside? No; range hoods without a duct, or ductless range hoods, can recirculate air back into your kitchen. However, to clean your kitchen air most efficiently, purchase a ducted range hood.

Is a microwave vent enough for a gas stove?

Microwaves that are designed to fit beneath or between cabinets or over a wall oven don't have vents built into the bottom. A vent is absolutely necessary if you're going to install your microwave over your stove top, so read the specifications on a new microwave carefully before purchasing it.

Can you have a stove without a hood?

It is not safe to cook without a range hood. Everyday cooking produces harmful contaminants including carbon dioxide, carbon monoxide, formaldehyde, and more. Without proper ventilation, these toxins sit in your kitchen and move to other areas of your home.

Are ductless range hoods worth it?

Unvented range hoods do filter some grease and cooking odors from the air, but the general consensus is that they're nowhere near as effective. Nor do they remove heat and humidity, so they won't help keep your kitchen cool while you cook. Above: An industrial-style vent (made of ducting) draws air up and out.

Does natural gas stove produce carbon monoxide?

Like other fuel-burning appliances, a gas stove produces carbon monoxide so it can cause carbon monoxide poisoning. That said, this doesn't necessarily mean your gas stove is unsafe, but it does mean you should be careful when using it.

What is the code for venting a gas cooktop?

Kitchens must be vented with a minimum of 25 CFM of continuous air or 100 CFM intermittent air.

How high should a range hood be above a gas stove?

For the professional gas cooking ranges, the most common range hood is the 18” canopy wall hood. This type of range hood should be installed at the height of 30” to 36” above the cooktop.

How much CFM do I need for gas range?

For gas cooking surfaces or range, a minimum ventilation level of 100 CFM (Cubic Feet per Minute) per 10,000 BTU is recommended. However, the hood must have a minimum of 500 CFM of ventilation power.

Is 400 cfm enough for a gas range?

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.

How high does a microwave have to be above a gas range?

According to the National Kitchen and Bath Association, the bottom of the microwave should be no higher than 54 inches above the floor, which would allow for 18 inches of clearance between the microwave and the typical cooktop height of 36 inches.

Do Over the range microwaves need to be vented outside?

There is no requirement that your Over The Range (OTR) Microwave be vented to the outdoors. All OTR microwave ovens can be set up to either allow the fan to recirculate the air back into the kitchen or be vented to the outdoors.

Do ductless range hoods remove smoke?

A ductless (or ventless) range hood does not vent out of the home, instead, it carries the debris and smoke form the air and filters it through a charcoal or carbon filter before releasing it back into the room. While many times this method is not as functional as a vented hood, it does work.

Do I need a downdraft on my gas cooktop?

Some stoves come with built-in downdraft vents that rise up from the back or center of the cooktop when a burner is lit. Like updraft hoods, downdraft units must be vented to the outdoors or they are ineffective. On a gas stove, a malfunctioning downdraft vent can allow dangerous carbon monoxide to remain in the air.

How does a ventless kitchen hood work?

How does a ductless range hood work? A ductless range hood works by sucking greasy kitchen air through mesh and baffle filters. Once the air passes via these filters, it moves through carbon filters that can trap dirt and then neutralize strong cooking odors.

What is the difference between duct and ductless range hoods?

The major difference between the two is that a ductless range hood, which is more common in most kitchens, uses a fan or blower motor to pull all the grease and smoke out of the air, then recirculates it. A ducted range hood, on the other hand, vents all the bad air straight to the outside.

Do ductless range hoods meet code?

Range hoods always need to vent to the exterior. They can't exhaust into an attic, a crawlspace, or inside a ceiling cavity. The main code exception is for ductless or recirculating range hoods as long as they are listed and designed for that type of installation.

Are ductless range hoods legal in California?

Although range hoods are not mandatory according to the IRC, California code requires mechanical ventilation in the kitchen that exhausts 100 CFM (intermittent ventilation) or allows 5 air changes per hour (continuous ventilation).

Why are gas stoves bad?

Natural gas and propane stoves can release carbon monoxide, formaldehyde and other harmful pollutants into the air, which can be toxic to people and pets. Using a wood stove or fireplace to cook can result in high levels of indoor air pollution from wood smoke.
